# PDFSigner Component

The PDFSigner component signs PDF documents digitally.

## Syntax

```text
TsbxPDFSigner
```

## Remarks

PDFSigner can sign PDF documents in accordance with a selection of PDF and PAdES signature standards.

```text
PDFSigner signer = new PDFSigner();

// Set the PDF document that you want to sign
signer.setInputFile("MyDocument.pdf");

// Set the path where you want the signed document to be saved
signer.setOutputFile("Signed.pdf");

// The certificate which the document will be signed with
signer.setSigningCertificate(new Certificate("Cert.pfx","password"));

// The signature level
signer.getNewSignature().setLevel(PDFSignature.paslBaselineT);
signer.getNewSignature().setHashAlgorithm("SHA512"); // Hashing algorithm used for signing, default SHA256

signer.setTimestampServer("https://..."); // The address of the timestamping server

signer.sign();
```

### Standards and technologies supported

PDFSigner can create PDF signatures that match the following baseline standards:

- Generic PDF signatures (ISO 32000)
- PAdES: all profiles are supported (BES, EPES, T, LTV, B-B, B-T, and others) (ETSI EN 319 142-1 and others)
- Signature and document timestamps using external TSAs.
- All industry-standard cryptographic algorithms (RSA, ECDSA, SHA256-512, and many others).

### Configuring the signature spec

Configuring PDFSigner to produce signatures of the right type is one of the most important questions you need to address. Normally the service or software you will be communicating your PDF documents to will provide you with the list of requirements that your signatures should match.

Typically, those will dictate the following key aspects of the signatures:

- Level (BES, T, or LTV). This can be adjusted with the  property (Note: when creating EPES signatures you need to provide the signature  and  properties).
- Timestamp requirement: provide the address of your online TSA service via the [TimestampServer](#timestampserver-property-pdfsigner-component) property.
- When creating LTV signatures, tune up validation parameters via the [RevocationCheck](#revocationcheck-property-pdfsigner-component), [OfflineMode](#offlinemode-property-pdfsigner-component), and [IgnoreChainValidationErrors](#ignorechainvalidationerrors-property-pdfsigner-component) properties.
- To create a document timestamp, sign your document first, and then sign the result again with  set to pslDocumentTimestamp and [TimestampServer](#timestampserver-property-pdfsigner-component) pointing to the TSA URL.

### Signing certificates

PDFSigner can use certificates residing on different media. Besides generic certificates stored in PFX or PEM files (A1), it can operate with non-exportable certificates residing on hardware media (A3) or in the cloud.

Non-exportable certificates can be accessed transparently via a Windows CSP or a PKCS#11 driver, if supplied by the certificate issuer. Proprietary interfaces can be plugged in with the *external signing* feature (see below).

You can use the [CertificateManager](CertificateManager.md#CertificateManager) and [CertificateStorage](CertificateStorage.md#CertificateStorage) components to load the signing certificate. Assign the certificate to the SigningCertificate property, and optionally provide the remainder of its chain via the SigningChain property.

**Note**: If signing with a non-exportable key (such as residing on a hardware device or in the cloud), please make sure you keep the original [CertificateStorage](CertificateStorage.md#CertificateStorage) object open until the signing is completed. This is because the storage component provides a 'bridge' to the private key. If the storage is closed prematurely, this bridge is destroyed, and the private key can't be used.

You don't need to provide a signing certificate or chain when creating document timestamp signatures, since this type of signature is done with a TSA's certificate.

### Widget adjustment

PDFSigner provides means to customize the look of the signature widget to be shown on the document page. Create your very own signatures in the form of your company's logo, a handwritten signature, or a wet seal.

Alternatively, you can choose not to associate any widget with your signature by setting  to true.

Please check out this [self-describing PDF document](https://www.nsoftware.com/kb/articles/file/widgets.pdf) for good guidance on widget positioning, background styles, and text formatting.

### Signing the document

Now that you have set up all signature, certificate, and widget properties, it is time to sign. You can provide the input document in one of the following forms: as a file (assign the path to the [InputFile](#inputfile-property-pdfsigner-component) property), as a stream (assign to the InputStream property), or as a byte array (assign to [InputBytes](#inputbytes-property-pdfsigner-component)). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via [OutputFile](#outputfile-property-pdfsigner-component) and OutputStream respectively, or by reading the resulting document bytes from the [OutputBytes](#outputbytes-property-pdfsigner-component) property after the signing.

Having set up the input and output, call the component's [Sign](#sign-method-pdfsigner-component) method. This will initiate the signing process. Depending on the settings, the signing may be as straightforward as calculating the document hash and signing it with the private key (e.g. in the PAdES-BES signing variant), or it may involve advanced chain validation routines (PAdES-LTV). During the latter, the component may contact a number of external revocation information sources (CRL and OCSP servers) to establish the validity of the signing certificate.

If a TSA server was provided via the [TimestampServer](#timestampserver-property-pdfsigner-component) property, the component will contact it too to timestamp the new signature.

During the signing, PDFSigner may fire events to let your code know of certain conditions. If the input document is encrypted but no decryption parameters were found in the [Password](#password-property-pdfsigner-component) and DecryptionCertificate properties, the component will fire the [Encrypted](#encrypted-event-pdfsigner-component) event to tell your code that it needs decryption information to be able to continue with the signing. It may fire [TLSCertValidate](#tlscertvalidate-event-pdfsigner-component) if one of the HTTP endpoints involved during the operation (which may be a CRL, OCSP, or TSA service) works over TLS and needs its certificate to be validated.

### External signing and DCAuth

PDFSigner, like many other components offered by the product, supports two methods of signing with external keys. These methods are fully independent of each other: you can choose the one that suits your usage scenario best.

**Synchronous method: ExternalSign**

This is a simpler method that basically lets you infiltrate into the heart of the signing routine by taking care of the hash signing operation. The component does the rest of the job (hash calculation, preparation of signature objects, CRL/OCSP retrieval).

To initiate this method, call [SignExternal](#signexternal-method-pdfsigner-component) instead of [Sign](#sign-method-pdfsigner-component). When the hash is ready, it will be passed back to your code with the [ExternalSign](#externalsign-event-pdfsigner-component) event. Your event handler needs to sign the hash with the private key and return the created signature back to the component - which will embed it into the document.

You don't need your signing certificate to contain an associated private key when using this method. The certificate itself (its public copy) may be needed though, as it is often included in the hash calculation.

This method is synchronous, meaning [SignExternal](#signexternal-method-pdfsigner-component) provides you the results immediately upon its completion.

**Asynchronous method: DCAuth**

DCAuth is a SecureBlackbox know-how technology. This protocol was designed to allow sharing of private keys across environments, allowing the signer and the private key to reside on different systems. It works in the following way:

- The signing party - such as PDFSigner - initiates the operation using a [SignAsyncBegin](#signasyncbegin-method-pdfsigner-component) call. This produces two outcomes: a *pre-signed document* (a document with a blank signature placeholder), and a *request state* (an object containing a hash that needs to be signed). At this point the PDFSigner instance can be released, and the process itself terminated (which may be useful when run as part of a web page).
- The *request state* is passed to the private key holder party. The private key holder passes the request state to a DCAuth object, which parses the request state, extracts the hash, and signs it. The output of DCAuth processing is another object, a *response state*, which contains the signature. The private key holder then sends the *response state* back to the signing party.
- The signing party re-creates the components and passes the *response state*, together with the pre-signed version of the document, to the signer's [SignAsyncEnd](#signasyncend-method-pdfsigner-component) method. [SignAsyncEnd](#signasyncend-method-pdfsigner-component) extracts the signature from the *response state* and incorporates it into the pre-signed document.

This method is asynchronous in that sense that from the signing party's viewpoint, it splits the signing operation into the *pre-signing* and *completion* stages which can be performed independently from each other and in different execution contexts. This makes this method particularly helpful for use in web pages and other scenarios where the signing key is not available in real time.

### Fine-grained chain validation setup

Chain validation is a sophisticated, multi-faceted procedure that involves a lot of variables. Depending on the configuration of your operating environment, the specifics of the PKI framework being used, and the validation policy you need to follow, you may want to tune up your chain validation parameters so they fit them best. A summary of such parameters is given below.

- [RevocationCheck](#revocationcheck-property-pdfsigner-component) lets you choose between and/or prioritize revocation origins. OCSP sources are often preferred to CRL because of their real-time capability and the smaller size of validation tokens they produce.
- [OfflineMode](#offlinemode-property-pdfsigner-component) is a master switch that stops the component from looking for any validation tokens online. If this property is switched on, the component will only use the KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
- [IgnoreChainValidationErrors](#ignorechainvalidationerrors-property-pdfsigner-component) makes the component ignore any major validation issues it encounters (such us an untrusted chain or missing CRL). This option is handy for debugging and for creating signatures in the environments where the signing certificate is not trusted.
- KnownCertificates, KnownCRLs, and KnownOCSPs let you provide your own validation material. This may be useful when working in [OfflineMode](#offlinemode-property-pdfsigner-component), where the signer has no access to the validation sources, or where the validation material has already been collected.
- TrustedCertificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative to it.
- BlockedCertificates lets you provide a list of blocked/distrusted certificates. Any CA certificate contained in it will be deemed untrusted/invalid.

The following parameters are not directly related to chain validation, but may have an implicit effect on it.

- Proxy, SocketSettings, and TLSSettings let you tune up the connectivity and TLS options in accordance with local preferences.
- TLSClientChain lets you provide the client certificate and its chain for TLS client authentication.
- Subscribe to [TLSCertValidate](#tlscertvalidate-event-pdfsigner-component) to validate any TLS certificates of the services involved in chain validation.

The results of the chain validation procedure, upon its completion, are published in the following properties:

- ChainValidationResult contains the primary result of the chain validation routine: valid, valid but untrusted, invalid, or undefined.
- ChainValidationDetails provides the details of the factors that contributed to the chain validation result, such as an outdated certificate, a missing CRL, or a missing CA certificate.
- ValidationLog contains the detailed chain validation log. The log can often be very helpful in nailing down various validation issues.

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

The *BlockedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [BlockedCertCount](#blockedcertcount-property-pdfsigner-component) property.

## Data Type

Integer

# CertBytes Property ([PDFSigner](#pdfsigner-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray CertBytes[int CertIndex] = { read=FCertBytes };
```

## Remarks

Returns the raw certificate data in DER format.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Byte Array

# CertCA Property ([PDFSigner](#pdfsigner-component) Component)

Indicates whether the certificate has a CA capability.

## Syntax

*C++ Builder Syntax*

```text
__property bool CertCA[int CertIndex] = { read=FCertCA };
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Boolean

# CertCAKeyID Property ([PDFSigner](#pdfsigner-component) Component)

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray CertCAKeyID[int CertIndex] = { read=FCertCAKeyID };
```

## Remarks

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [CertSubjectKeyID](#certsubjectkeyid-property-pdfsigner-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Byte Array

# CertType Property ([PDFSigner](#pdfsigner-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxPDFSignerCertTypes CertType[int CertIndex] = { read=FCertType };
enum TsbxPDFSignerCertTypes {
  ctUnknown=0,
  ctX509Certificate=1,
  ctX509CertificateRequest=2
};
```

## Default Value

ctUnknown

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_Certificate) object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the [CertificateManager](#CertificateManager) component to load or create new certificate and certificate requests objects.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Integer

# CertCRLDistributionPoints Property ([PDFSigner](#pdfsigner-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*C++ Builder Syntax*

```text
__property String CertCRLDistributionPoints[int CertIndex] = { read=FCertCRLDistributionPoints };
```

## Default Value

""

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

String

# CertCurve Property ([PDFSigner](#pdfsigner-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*C++ Builder Syntax*

```text
__property String CertCurve[int CertIndex] = { read=FCertCurve };
```

## Default Value

""

## Remarks

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

# ExternalCryptoKeyID Property ([PDFSigner](#pdfsigner-component) Component)

The ID of the pre-shared key used for DC request authentication.

## Syntax

*C++ Builder Syntax*

```text
__property String ExternalCryptoKeyID = { read=FExternalCryptoKeyID, write=FSetExternalCryptoKeyID };
```

## Default Value

""

## Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use [ExternalCryptoKeySecret](#externalcryptokeysecret-property-pdfsigner-component) to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example:

```text
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";
```

## Data Type

String

# ExternalCryptoKeySecret Property ([PDFSigner](#pdfsigner-component) Component)

```text
__property bool NewSigCertification = { read=FNewSigCertification, write=FSetNewSigCertification };
```

## Default Value

false

## Remarks

Specifies whether this is a Certification (MDP) signature.

Certification signatures certify the current revision of the document and define which changes, if any, may be made afterwards without invalidating that certification. Use [NewSigAllowedChanges](#newsigallowedchanges-property-pdfsigner-component) to specify the permitted changes.

A PDF document normally contains at most one certification signature, and it is the first signature in the document. This setting does not apply to document timestamps.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is not available at design time.

## Data Type

## Remarks

The outcome of a certificate chain validation routine.

Available options:

|  |  |  |
| --- | --- | --- |
| cvtValid | 0 | The chain is valid |
| cvtValidButUntrusted | 1 | The chain is valid, but the root certificate is not trusted |
| cvtInvalid | 2 | The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature) |
| cvtCantBeEstablished | 3 | The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses) |

Use the ValidationLog property to access the detailed validation log.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is read-only and not available at design time.

## Data Type

Integer

# NewSigClaimedSigningTime Property ([PDFSigner](#pdfsigner-component) Component)

Returns or sets the signature's creation time.

## Syntax

*C++ Builder Syntax*

```text
__property String NewSigClaimedSigningTime = { read=FNewSigClaimedSigningTime, write=FSetNewSigClaimedSigningTime };
```

## Default Value

""

## Remarks

Returns or sets the signature's creation time.

Use this property to get or set the signature creation time from the signer's computer. The claimed time, unlike [NewSigValidatedSigningTime](#newsigvalidatedsigningtime-property-pdfsigner-component), does not originate from a trusted TSA and may be forged or wrong. If this value is not set when a new signature is created, the component uses the current UTC time.

The time is provided in UTC.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is not available at design time.

## Data Type

# NewSigCompatibilityErrors Property ([PDFSigner](#pdfsigner-component) Component)

Returns compatibility errors encountered during validation.

## Syntax

*C++ Builder Syntax*

```text
__property int NewSigCompatibilityErrors = { read=FNewSigCompatibilityErrors };
```

## Default Value

0

## Remarks

Returns compatibility errors encountered during validation.

Use this property to get specific compatibility errors encountered during validation. Unlike chain validation details, compatibility errors indicate violations by the signature of the assumed signature level/profile. For example, BES signatures are required to contain the signing time attribute. A prospective BES signature without such attribute will invoke a compatibility error.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is read-only and not available at design time.

## Data Type

Integer

# NewSigContactInfo Property ([PDFSigner](#pdfsigner-component) Component)

Contains the signer's contact information.

## Syntax

*C++ Builder Syntax*

```text
__property String NewSigContactInfo = { read=FNewSigContactInfo, write=FSetNewSigContactInfo };
```

## Default Value

""

## Remarks

Contains the signer's contact information. This is a PDF document property.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is not available at design time.

## Data Type

String

# NewSigContainsLongTermInfo Property ([PDFSigner](#pdfsigner-component) Component)

Returns true if the signature was found to contain long-term validation details (certificates, CRLs, and OCSP response).

## Syntax

*C++ Builder Syntax*

```text
__property bool NewSigContainsLongTermInfo = { read=FNewSigContainsLongTermInfo };
```

## Default Value

false

## Remarks

Returns true if the signature was found to contain long-term validation details (certificates, CRLs, and OCSP response).

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is read-only and not available at design time.

## Data Type

Boolean

# NewSigCoverageEndsAt Property ([PDFSigner](#pdfsigner-component) Component)

Indicates the byte offset in the PDF file where signature coverage ends.

## Syntax

*C++ Builder Syntax*

```text
__property int NewSigCoverageEndsAt = { read=FNewSigCoverageEndsAt };
```

## Default Value

0

## Remarks

Indicates the byte offset in the PDF file where signature coverage ends.

PDF generators often use incremental updates to make changes in the documents. This may result in the signature only covering a part of the document (one of the past revisions), but not the subsequent changes.

Use this property to identify the offset where the signature coverage ends. One option is to compare it to the length of the whole document. Alternatively, use the [GetSignedVersion](#PDFVerifier_m_GetSignedVersion) method of the PDFVerifier component to extract the exact revision that was signed.

A value of **-1** indicates that the component could not determine the coverage offset.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is read-only and not available at design time.

## Data Type

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray NewSigCustomData = { read=FNewSigCustomData, write=FSetNewSigCustomData };
```

## Remarks

Uninterpreted custom data to save with the PDF signature. The component stores and returns this value as-is and does not validate its contents.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is not available at design time.

## Data Type

Byte Array

# NewSigEmptyField Property ([PDFSigner](#pdfsigner-component) Component)

Indicates whether the signature is created as an empty property (a signature placeholder).

## Syntax

*C++ Builder Syntax*

```text
__property bool NewSigEmptyField = { read=FNewSigEmptyField, write=FSetNewSigEmptyField };
```

## Default Value

false

## Remarks

Indicates whether the signature is created as an empty field (a signature placeholder).

An empty field reserves a place for a future signature but does not contain a cryptographic signature value.

NOTE: This property is only applicable for creating new empty signature fields. To read info about empty signature fields, use EmptySignatureFieldCount and other EmptySignatureFields* configuration settings.

The ** parameter specifies the index of the item in the array. The size of the array is controlled by the [NewSigCount](#PDFSigner_p_NewSigCount) property.

This property is not available at design time.

```

## Default Value

""

## Remarks

Specifies the PDF security handler filter name to use when creating a new signature.

This value determines how PDF viewers, such as Adobe Acrobat Reader, interpret and validate the digital signature. Commonly recognized values include:

- "Adobe.PPKLite" - the default value; instructs Adobe to use its built-in certificate infrastructure.
- "Adobe.PPKMS" - instructs Adobe to use the system-wide Windows certificate store for signature validation.

Custom values (e.g. "VeriSign.PPKVS" used by the VeriSign plug-in) are also supported. However, non-standard filter names may not be recognized by all PDF viewers or validators, which could lead to compatibility or validation issues.

For maximum compatibility across different PDF environments, it is recommended to use the default value **"Adobe.PPKLite"** unless integration with a specific custom handler is required.

## Syntax

__property TsbxPDFSignerNewSigLevels NewSigLevel = { read=FNewSigLevel, write=FSetNewSigLevel };
enum TsbxPDFSignerNewSigLevels {
  paslUnknown=0,
  paslGeneric=1,
  paslBaselineB=2,
  paslBaselineT=3,
  paslBaselineLT=4,
  paslBaselineLTA=5,
  paslBES=6,
  paslEPES=7,
  paslLTV=8
};
```

## Default Value

paslBaselineB

## Remarks

Specifies the PAdES signature level.

PAdES standard defines a number of different 'levels' of signatures which can be used for different purposes.

Note that when validating a signature, the LTV modifier may be affected by the validation settings. These include OfflineMode (set it to true to obtain the clean LTV capability) and certificate caching (switch it off to stop earlier validations from affecting the current validation).

The supported levels are:

|  |  |  |
| --- | --- | --- |
| paslUnknown | 0 | Unknown signature level |
| paslGeneric | 1 | Generic signature: Legacy Adobe signature (adbe.pkcs7.detached), corresponds to pstLegacy signature type |
| paslBaselineB | 2 | Baseline B (B-B, basic) |
| paslBaselineT | 3 | Baseline T (B-T, timestamped) |
| paslBaselineLT | 4 | Baseline LT (B-LT, long-term) |
| paslBaselineLTA | 5 | Baseline LTA (B-LTA, long-term with archived timestamp) |
| paslBES | 6 | BES (Basic Electronic Signature) |
| paslEPES | 7 | EPES (Electronic Signature with an Explicit Policy) |
| paslLTV | 8 | LTV (Electronic Signature with with revocation info) |

When creating a signature, some levels require additional settings:

- **paslBaselineT** requires a timestamp server.
- **paslBaselineLT**, **paslBaselineLTA**, and **paslLTV** require deep validation and a timestamp server.
- **paslEPES** requires [NewSigPolicyID](#newsigpolicyid-property-pdfsigner-component), [NewSigPolicyHashAlgorithm](#newsigpolicyhashalgorithm-property-pdfsigner-component), and [NewSigPolicyHash](#newsigpolicyhash-property-pdfsigner-component).

When evaluating the level of a PAdES signature, SecureBlackbox uses the following criteria and conditions:

- If the signing chain is found to be invalid or incomplete, the level will be reported as **Baseline-B**, **BES**, or **EPES**, depending on the attributes included in the signature (such as policy details).
- If the signing chain is found to be valid, the signature includes a timestamp, and the timestamp chain is valid (or the IgnoreTimestampChainValidityForLevelDetection config property is set to true), the level will be reported as **Baseline-T**.
- If the Baseline-T conditions above are met, and all the validation material is included in the DSS, the level will be reported as **Baseline-LT**.
- If the Baseline-LT conditions above are met, and the signature is protected by a later document timestamp, the level will be reported as **Baseline-LTA**.
- If the signing chain is found to be valid, the signature includes a timestamp, and the timestamp chain is valid (or the IgnoreTimestampChainValidityForLevelDetection config property is set to true), and all the validation material is included in the DSS *or signature*, and the signature does not meet the Baseline-LT and Baseline-LTA criteria, the level will be reported as LTV. In other words, the LTV level is a relaxed version of Baseline-LT, that allows the validation material to be included in the signature itself and not DSS.

Note: The *LTV-enabled* property reported by Adobe Reader can be misleading, as it does not represent a valid PAdES level. Instead, it is a rather indicative claim that advises that the signature does include some form of an external timestamp (a signature timestamp or a document timestamp) and some piece of validation material, and the signing chain ends up with a local trust anchor. As such, it can be a much weaker property than the Baseline-LT, Baseline-LTA, and LTV levels reported by SecureBlackbox.

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

  crcAllCRLAndOCSP=4,
  crcAnyCRL=5,
  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};
```

## Default Value

crcAuto

## Remarks

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

# SignatureCertification Property ([PDFSigner](#pdfsigner-component) Component)

Specifies whether this is a Certification (MDP) signature.

## Syntax

*C++ Builder Syntax*

```text
__property bool SignatureCertification[int SignatureIndex] = { read=FSignatureCertification };
```

## Default Value

false

## Remarks

Specifies whether this is a Certification (MDP) signature.

Certification signatures certify the current revision of the document and define which changes, if any, may be made afterwards without invalidating that certification. Use [SignatureAllowedChanges](#signatureallowedchanges-property-pdfsigner-component) to specify the permitted changes.

A PDF document normally contains at most one certification signature, and it is the first signature in the document. This setting does not apply to document timestamps.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

enum TsbxPDFSignerSignatureChainValidationResults {
  cvtValid=0,
  cvtValidButUntrusted=1,
  cvtInvalid=2,
  cvtCantBeEstablished=3
};
```

## Default Value

Available options:

|  |  |  |
| --- | --- | --- |
| cvtValid | 0 | The chain is valid |
| cvtValidButUntrusted | 1 | The chain is valid, but the root certificate is not trusted |
| cvtInvalid | 2 | The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature) |
| cvtCantBeEstablished | 3 | The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses) |

Use the ValidationLog property to access the detailed validation log.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

## Data Type

Integer

# SignatureClaimedSigningTime Property ([PDFSigner](#pdfsigner-component) Component)

Returns or sets the signature's creation time.

## Syntax

*C++ Builder Syntax*

```text
__property String SignatureClaimedSigningTime[int SignatureIndex] = { read=FSignatureClaimedSigningTime };
```

## Default Value

""

## Remarks

Returns or sets the signature's creation time.

Use this property to get or set the signature creation time from the signer's computer. The claimed time, unlike [SignatureValidatedSigningTime](#signaturevalidatedsigningtime-property-pdfsigner-component), does not originate from a trusted TSA and may be forged or wrong. If this value is not set when a new signature is created, the component uses the current UTC time.

The time is provided in UTC.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

String

# SignatureCompatibilityErrors Property ([PDFSigner](#pdfsigner-component) Component)

Returns compatibility errors encountered during validation.

## Syntax

*C++ Builder Syntax*

```text
__property int SignatureCompatibilityErrors[int SignatureIndex] = { read=FSignatureCompatibilityErrors };
```

## Default Value

0

## Remarks

Returns compatibility errors encountered during validation.

Use this property to get specific compatibility errors encountered during validation. Unlike chain validation details, compatibility errors indicate violations by the signature of the assumed signature level/profile. For example, BES signatures are required to contain the signing time attribute. A prospective BES signature without such attribute will invoke a compatibility error.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Integer

# SignatureContactInfo Property ([PDFSigner](#pdfsigner-component) Component)

Contains the signer's contact information.

## Syntax

*C++ Builder Syntax*

## Syntax

*C++ Builder Syntax*

```text
__property bool SignatureContainsLongTermInfo[int SignatureIndex] = { read=FSignatureContainsLongTermInfo };
```

## Default Value

false

## Remarks

Returns true if the signature was found to contain long-term validation details (certificates, CRLs, and OCSP response).

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Boolean

# SignatureCoverageEndsAt Property ([PDFSigner](#pdfsigner-component) Component)

Indicates the byte offset in the PDF file where signature coverage ends.

## Syntax

*C++ Builder Syntax*

```text
__property int SignatureCoverageEndsAt[int SignatureIndex] = { read=FSignatureCoverageEndsAt };
```

## Default Value

0

## Remarks

Indicates the byte offset in the PDF file where signature coverage ends.

PDF generators often use incremental updates to make changes in the documents. This may result in the signature only covering a part of the document (one of the past revisions), but not the subsequent changes.

Use this property to identify the offset where the signature coverage ends. One option is to compare it to the length of the whole document. Alternatively, use the [GetSignedVersion](#PDFVerifier_m_GetSignedVersion) method of the PDFVerifier component to extract the exact revision that was signed.

A value of **-1** indicates that the component could not determine the coverage offset.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

```

## Remarks

Uninterpreted custom data to save with the PDF signature. The component stores and returns this value as-is and does not validate its contents.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

Byte Array

# SignatureEmptyField Property ([PDFSigner](#pdfsigner-component) Component)

Indicates whether the signature is created as an empty property (a signature placeholder).

## Syntax

*C++ Builder Syntax*

```text
__property bool SignatureEmptyField[int SignatureIndex] = { read=FSignatureEmptyField };
```

## Default Value

false

## Remarks

Indicates whether the signature is created as an empty field (a signature placeholder).

An empty field reserves a place for a future signature but does not contain a cryptographic signature value.

NOTE: This property is only applicable for creating new empty signature fields. To read info about empty signature fields, use EmptySignatureFieldCount and other EmptySignatureFields* configuration settings.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

__property String SignatureEntityLabel[int SignatureIndex] = { read=FSignatureEntityLabel };
```

## Default Value

""

## Remarks

Use this property to get the signature entity label.

This property returns a string label that uniquely identifies the signature. The label can be used to establish the signature target in the SignatureFound event or to select the signing chain via the SelectInfo method.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

String

# SignatureFilterName Property ([PDFSigner](#pdfsigner-component) Component)

Specifies the PDF security handler filter name to use when creating a new signature.

## Syntax

*C++ Builder Syntax*

```text
__property String SignatureFilterName[int SignatureIndex] = { read=FSignatureFilterName };
```

## Default Value

""

## Remarks

Specifies the PDF security handler filter name to use when creating a new signature.

This value determines how PDF viewers, such as Adobe Acrobat Reader, interpret and validate the digital signature. Commonly recognized values include:

- "Adobe.PPKLite" - the default value; instructs Adobe to use its built-in certificate infrastructure.
- "Adobe.PPKMS" - instructs Adobe to use the system-wide Windows certificate store for signature validation.

Custom values (e.g. "VeriSign.PPKVS" used by the VeriSign plug-in) are also supported. However, non-standard filter names may not be recognized by all PDF viewers or validators, which could lead to compatibility or validation issues.

For maximum compatibility across different PDF environments, it is recommended to use the default value **"Adobe.PPKLite"** unless integration with a specific custom handler is required.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

Specifies the full name of the signature field.

This is an internal identifier of a signature (such as Signature1) and is not meant to be human-readable.

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

This property is read-only and not available at design time.

## Data Type

String

# SignatureHandle Property ([PDFSigner](#pdfsigner-component) Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

## Syntax

*C++ Builder Syntax*

```text
__property __int64 SignatureHandle[int SignatureIndex] = { read=FSignatureHandle };
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

The *SignatureIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-pdfsigner-component) property.

## Data Type

String

# SignatureLevel Property ([PDFSigner](#pdfsigner-component) Component)

Specifies the PAdES signature level.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxPDFSignerSignatureLevels SignatureLevel[int SignatureIndex] = { read=FSignatureLevel };
enum TsbxPDFSignerSignatureLevels {
  paslUnknown=0,
  paslGeneric=1,
  paslBaselineB=2,
  paslBaselineT=3,
  paslBaselineLT=4,
  paslBaselineLTA=5,
  paslBES=6,
  paslEPES=7,
  paslLTV=8
};
```

## Default Value

paslBaselineB

## Remarks

Specifies the PAdES signature level.

PAdES standard defines a number of different 'levels' of signatures which can be used for different purposes.

Note that when validating a signature, the LTV modifier may be affected by the validation settings. These include OfflineMode (set it to true to obtain the clean LTV capability) and certificate caching (switch it off to stop earlier validations from affecting the current validation).

The supported levels are:

|  |  |  |
| --- | --- | --- |
| paslUnknown | 0 | Unknown signature level |
| paslGeneric | 1 | Generic signature: Legacy Adobe signature (adbe.pkcs7.detached), corresponds to pstLegacy signature type |
| paslBaselineB | 2 | Baseline B (B-B, basic) |
| paslBaselineT | 3 | Baseline T (B-T, timestamped) |
| paslBaselineLT | 4 | Baseline LT (B-LT, long-term) |
| paslBaselineLTA | 5 | Baseline LTA (B-LTA, long-term with archived timestamp) |
| paslBES | 6 | BES (Basic Electronic Signature) |
| paslEPES | 7 | EPES (Electronic Signature with an Explicit Policy) |
| paslLTV | 8 | LTV (Electronic Signature with with revocation info) |

When creating a signature, some levels require additional settings:

- **paslBaselineT** requires a timestamp server.
- **paslBaselineLT**, **paslBaselineLTA**, and **paslLTV** require deep validation and a timestamp server.
- **paslEPES** requires [SignaturePolicyID](#signaturepolicyid-property-pdfsigner-component), [SignaturePolicyHashAlgorithm](#signaturepolicyhashalgorithm-property-pdfsigner-component), and [SignaturePolicyHash](#signaturepolicyhash-property-pdfsigner-component).

When evaluating the level of a PAdES signature, SecureBlackbox uses the following criteria and conditions:

- If the signing chain is found to be invalid or incomplete, the level will be reported as **Baseline-B**, **BES**, or **EPES**, depending on the attributes included in the signature (such as policy details).
- If the signing chain is found to be valid, the signature includes a timestamp, and the timestamp chain is valid (or the IgnoreTimestampChainValidityForLevelDetection config property is set to true), the level will be reported as **Baseline-T**.
- If the Baseline-T conditions above are met, and all the validation material is included in the DSS, the level will be reported as **Baseline-LT**.
- If the Baseline-LT conditions above are met, and the signature is protected by a later document timestamp, the level will be reported as **Baseline-LTA**.
- If the signing chain is found to be valid, the signature includes a timestamp, and the timestamp chain is valid (or the IgnoreTimestampChainValidityForLevelDetection config property is set to true), and all the validation material is included in the DSS *or signature*, and the signature does not meet the Baseline-LT and Baseline-LTA criteria, the level will be reported as LTV. In other words, the LTV level is a relaxed version of Baseline-LT, that allows the validation material to be included in the signature itself and not DSS.

Note: The *LTV-enabled* property reported by Adobe Reader can be misleading, as it does not represent a valid PAdES level. Instead, it is a rather indicative claim that advises that the signature does include some form of an external timestamp (a signature timestamp or a document timestamp) and some piece of validation material, and the signing chain ends up with a local trust anchor. As such, it can be a much weaker property than the Baseline-LT, Baseline-LTA, and LTV levels reported by SecureBlackbox.

## Data Type

Integer

# TimestampServer Property ([PDFSigner](#pdfsigner-component) Component)

The address of the timestamping server.

## Syntax

*C++ Builder Syntax*

```text
__property String TimestampServer = { read=FTimestampServer, write=FSetTimestampServer };
```

## Default Value

""

## Remarks

Use this property to provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature.

SecureBlackbox supports RFC3161-compliant timestamping servers, available via HTTP or HTTPS.

If your timestamping service enforces credential-based user authentication (basic or digest), you can provide the credentials in the same URL:

http://user:password@timestamp.server.com/TsaService

For TSAs using certificate-based TLS authentication, provide the client certificate via the TLSClientChain property.

If this property is left empty, no timestamp will be added to the signature.

Starting from summer 2021 update (Vol. 2), the *virtual* timestamping service is supported, which allows you to intervene in the timestamping routine and provide your own handling for the TSA exchange. This may be handy if the service that you are requesting timestamps from uses a non-standard TSP protocol or requires special authentication option.

To employ the virtual service, assign an URI of the following format to this property:

virtual://localhost?hashonly=true&includecerts=true&reqpolicy=1.2.3.4.5&halg=SHA256&ignorenonce=true

Subscribe to [Notification](#notification-event-pdfsigner-component) event to get notified about the virtualized timestamping event. The EventID of the timestamping event is TimestampRequest. Inside the event handler, read the base16-encoded request from the EventParam parameter and forward it to the timestamping authority. Upon receiving the response, pass it back to the component, encoded in base16, via the TimestampResponse config property:

component.Config("TimestampResponse=308208ab...");

Note that all the exchange with your custom TSA should take place within the same invocation of the Notification event.

The *hashonly* parameter of the virtual URI tells the component to only return the timestamp message imprint via the EventParam parameter. If set to false, EventParam will contain the complete RFC3161 timestamping request.

The *includecerts* parameter specifies that the requestCertificates parameter of the timestamping request should be set to true.

The *reqpolicy* parameter lets you specify the request policy, and the *halg* parameter specifies the hash algorithm to use for timestamping.

The *ignorenonce* parameter allows you to switch off client nonce verification to enable compatibility with TSA services that do not support nonce mirroring.

All the parameters are optional.

# TLSRevocationCheck Property ([PDFSigner](#pdfsigner-component) Component)

Specifies the kind(s) of revocation check to perform.

## Syntax

*C++ Builder Syntax*

```text
__property TsbxPDFSignerTLSRevocationChecks TLSRevocationCheck = { read=FTLSRevocationCheck, write=FSetTLSRevocationCheck };
enum TsbxPDFSignerTLSRevocationChecks {
  crcNone=0,
  crcAuto=1,

  crcAllCRLAndOCSP=4,
  crcAnyCRL=5,
  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};
```

## Default Value

crcAuto

## Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

This property is not available at design time.

## Data Type

Integer

# WidgetBackgroundMask Property ([PDFSigner](#pdfsigner-component) Component)

Contains the background image mask.

## Syntax

*C++ Builder Syntax*

```text
__property DynamicArray WidgetBackgroundMask = { read=FWidgetBackgroundMask, write=FSetWidgetBackgroundMask };
```

## Remarks

Contains the background image mask.

Masks provide a means for marking transparent areas on your signature widgets. Specifically, a transparency mask tells PDF viewing apps which pixels of the signature widget should be kept visible and which should be rendered transparent instead.

In most cases, you will need a unique mask that is tailored for your signature widget image. This is something that you will need to create yourself based on your preferences and the actual image design.

A mask is effectively a matrix of bits, with each bit corresponding to a pixel on your background bitmap. A bit is set to 1 if the corresponding pixel needs to be made transparent, or to 0 if it needs to be opaque.

To create the mask that can be passed to BackgroundMask, please follow the below procedure:

Go through your signature widget bitmap row by row, processing each row of pixels from left to right. For each row,

1. Start with an empty bit string.

2. For every pixel in a row, add a '1' bit if you want it to be transparent, or a '0' bit if you want it to be opaque.

3. Upon reaching the end of the row, append '0' bits to your bit string until the number of bits in it is a multiple of 8. This is because each row of pixels needs to be represented with a whole number of bytes.

4. Convert the bit string to a byte array by grouping every 8 bits into a byte.

Do the same for every row of pixels, and then concatenate the received byte arrays together. Pass the created byte array to BackgroundMask.

A small example. Imagine your image is 19 pixels wide and 3 pixels tall. Imagine you want to make it 'semi-transparent' by using a 'mesh' pattern. The mask will therefore look like this:

10101010 10101010 10100000 // first row

01010101 01010101 01000000 // second row

10101010 10101010 10100000 // third row

Note that the last 5 bits of each row are padding '0' bits and are ignored: you only need them to make each row contain a whole number of bytes. When converted to a byte string, this would look like

0xAA 0xAA 0xA0

0x55 0x55 0x40

0xAA 0xAA 0xA0

, or, if written as a byte array, (0xAA, 0xAA, 0xA0, 0x55, 0x55, 0x40, 0xAA, 0xAA, 0xA0): this is what you need to pass to BackgroundMask.

This property is not available at design time.

# WidgetFontName Property ([PDFSigner](#pdfsigner-component) Component)

Specifies the font name for the signature text.

## Syntax

*C++ Builder Syntax*

```text
__property String WidgetFontName = { read=FWidgetFontName, write=FSetWidgetFontName };
```

## Default Value

""

## Remarks

Specifies the font name for the signature text.

Use this property to specify a Type 1 or TrueType font name for the signature text. If this property is empty, the widget uses the standard PDF *Helvetica* font.

The PDF format supports 14 standard Type 1 fonts, specifically: "Times-Roman", "Helvetica", "Courier", "Symbol", "Times-Bold", "Helvetica-Bold", "Courier-Bold", "ZapfDingbats", "Times-Italic", "Helvetica-Oblique", "Courier-Oblique", "Times-BoldItalic", "Helvetica-BoldOblique", "Courier-BoldOblique".

Standard Type 1 fonts are used as standard PDF fonts and are not embedded by the component. If the target document profile, such as PDF/A, requires fonts used in visible text to be embedded, specify a TrueType font.

For TrueType fonts, the component supports a full font name (e.g. "Times New Roman", "Arial Bold Italic"), a file name (e.g. "times.ttf", "arialbi.ttf"), or a full file path.

If a TrueType font is used, then a font subset is embedded into the PDF document.

The list of system TrueType font names that the component supports can be obtained using the [DoAction](#doaction-method-pdfsigner-component) method with the "GetSystemFontNames" action ID.

Use the [FontPaths](#FontPaths) configuration setting (accessed via [Config](#config-method-pdfsigner-component)) to specify font search paths when a TrueType font is specified without a full file path. The [FontPaths](#FontPaths) setting contains a CRLF-separated list of directories. Alternatively, specify the full path to the TrueType font file in this property.

## Remarks

Specifies whether to show the signature's status icon.

It is a good idea to avoid using the visual status icon, as described below:

According to the Digital Signature Appearances Adobe Acrobat SDK (May 2015), "Prior to Acrobat 6.0, signature appearances were manipulated at run-time in order to display the validity of the signature. The validity was shown as a graphic icon and with an additional, optional text message. The manipulated portions of the signature appearance were contained in layers n1, n3 and n4. Beginning with version 6, Acrobat does not maintain support for signature appearances that can be manipulated, though legacy signatures with these appearances may continue to display correctly. Use of layers n1, n3, and n4 is not recommended."

# Sign Method ([PDFSigner](#pdfsigner-component) Component)

Signs a PDF document.

## Syntax

*C++ Builder Syntax*

```text
void __fastcall Sign();
```

## Remarks

Call this method to sign the document referenced by the [InputFile](#inputfile-property-pdfsigner-component) (or InputStream) property. The document will be signed with SigningCertificate as configured in NewSignature, and saved in [OutputFile](#outputfile-property-pdfsigner-component) (OutputStream).

Use TrustedCertificates, KnownCertificates, [RevocationCheck](#revocationcheck-property-pdfsigner-component), [OfflineMode](#offlinemode-property-pdfsigner-component) and other properties of the component to adjust chain validation parameters. After the signing, the chain validation log will be available in the  property.

# SignAsyncBegin Method ([PDFSigner](#pdfsigner-component) Component)

Initiates the asynchronous signing operation.

## Syntax

*C++ Builder Syntax*

```text
String __fastcall SignAsyncBegin();
```

## Remarks

When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in [OutputFile](#outputfile-property-pdfsigner-component) (or OutputStream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.

Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to [InputFile](#inputfile-property-pdfsigner-component) (or InputStream), and call [SignAsyncEnd](#signasyncend-method-pdfsigner-component) to finalize the signing.

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the *ExternalCrypto.AsyncDocumentID* property to supply a unique document ID to include in the request. This is helpful when creating batches of multiple async requests, as it allows you to pass the whole response batch to [SignAsyncEnd](#signasyncend-method-pdfsigner-component) and expect it to recover the correct response from the batch automatically.

*AsyncState* is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the [SignAsyncEnd](#signasyncend-method-pdfsigner-component) method.

There are some conditions that should be met when signing PDF documents asynchronously. The advanced PDF signature levels, specifically BES, EPES, and LTV, require that the 'signingCertificate' attribute is included in the signature. This can only be satisfied if either ExternalCrypto is configured to use the asmdPKCS7 method, or the public copy of the signing certificate is provided on the pre-signing stage.

Please note that you will still be able to sign a document with the asmdPKCS1 method and no public copy of the certificate provided (resulting in the omission of the 'signingCertificate' attribute from the signature); however, most modern PDF processors will reject such signatures as invalid or non-compliant.

# SignAsyncEnd Method ([PDFSigner](#pdfsigner-component) Component)

Completes the asynchronous signing operation.

## Syntax

*C++ Builder Syntax*

```text
void __fastcall SignAsyncEnd(String AsyncReply);
```

## Remarks

When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.

Before calling this method, assign the path to the pre-signed copy of the document obtained from the prior [SignAsyncBegin](#signasyncbegin-method-pdfsigner-component) call to [InputFile](#inputfile-property-pdfsigner-component) (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to [OutputFile](#outputfile-property-pdfsigner-component) (or OutputStream).

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the *ExternalCrypto.AsyncDocumentID* parameter to pass a specific document ID if using batched AsyncReply. If used, it should match the value provided on the pre-signing ([SignAsyncBegin](#signasyncbegin-method-pdfsigner-component)) stage.

*AsyncState* is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the [SignAsyncBegin](#signasyncbegin-method-pdfsigner-component) method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

# SignExternal Method ([PDFSigner](#pdfsigner-component) Component)

Signs the document using an external signing facility.

## Syntax

*C++ Builder Syntax*

```text
void __fastcall SignExternal();
```

## Remarks

Use this method to create a PDF signature using an external signing facility for the cryptographic computations. SignExternal delegates the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and the hash is computed, the component fires the [ExternalSign](#externalsign-event-pdfsigner-component) event which allows the hash value to be passed for signing.

# Update Method ([PDFSigner](#pdfsigner-component) Component)

Updates a signature.

## Syntax

*C++ Builder Syntax*

```text
void __fastcall Update(String SigLabel);
```

## Remarks

PDF signatures may be updated from time to time by embedding newer/missing revocation information. The update approach is typically used to extend the validity of an LTV signature. Set *SigLabel* to the label of the signature field to update.

Updating is typically accompanied with a document timestamping operation. Set [TimestampServer](#timestampserver-property-pdfsigner-component) to have the component obtain and embed a document timestamp for you.

Before calling this method, provide the signed document via the [InputFile](#inputfile-property-pdfsigner-component) (or InputStream) property. The updated document will be saved to [OutputFile](#outputfile-property-pdfsigner-component) (or OutputStream).

# ChainElementDownload Event ([PDFSigner](#pdfsigner-component) Component)

Fires when there is a need to download a chain element from an online source.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Kind;
  String CertRDN;
  String CACertRDN;
  String Location;
  int Action;
} TsbxPDFSignerChainElementDownloadEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerChainElementDownloadEvent)(System::TObject* Sender, TsbxPDFSignerChainElementDownloadEventParams *e);
__property TsbxPDFSignerChainElementDownloadEvent OnChainElementDownload = { read=FOnChainElementDownload, write=FOnChainElementDownload };
```

## Remarks

Subscribe to this event to be notified about validation element retrievals. Use the *Action* parameter to suppress the download if required.

|  |  |  |
| --- | --- | --- |

# ChainValidated Event ([PDFSigner](#pdfsigner-component) Component)

Reports the completion of a certificate chain validation.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Index;
  String EntityLabel;
  String SubjectRDN;
  int ValidationResult;
  int ValidationDetails;
  bool Cancel;
} TsbxPDFSignerChainValidatedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerChainValidatedEvent)(System::TObject* Sender, TsbxPDFSignerChainValidatedEventParams *e);
__property TsbxPDFSignerChainValidatedEvent OnChainValidated = { read=FOnChainValidated, write=FOnChainValidated };
```

## Remarks

| cvtInvalid | 2 | The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature) |
| cvtCantBeEstablished | 3 | The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses) |

 Any other value reports a failure, and *ValidationDetails* provides more details on its reasons.

|  |  |  |
| --- | --- | --- |
| cvrBadData | 0x0001 | One or more certificates in the validation path are malformed |
| cvrRevoked | 0x0002 | One or more certificates are revoked |

# ChainValidationProgress Event ([PDFSigner](#pdfsigner-component) Component)

This event is fired multiple times during chain validation to report various stages of the validation procedure.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String EventKind;
  String CertRDN;
  String CACertRDN;
  int Action;
} TsbxPDFSignerChainValidationProgressEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerChainValidationProgressEvent)(System::TObject* Sender, TsbxPDFSignerChainValidationProgressEventParams *e);
__property TsbxPDFSignerChainValidationProgressEvent OnChainValidationProgress = { read=FOnChainValidationProgress, write=FOnChainValidationProgress };
```

## Remarks

Subscribe to this event to be notified about chain validation progress. Use the *Action* parameter to alter the validation flow.

The *EventKind* parameter reports the nature of the event being reported. The *CertRDN* and *CACertRDN* parameters report the distinguished names of the certificates that are relevant for the event invocation (one or both can be empty, depending on *EventKind*). Use the *Action* parameter to adjust the validation flow.

|  |  |  |
| --- | --- | --- |
| veaAuto | 0 | Handle the action automatically (the default behaviour) |
| veaContinue | 1 | Accept the request implied by the event (accept the certificate, allow the object retrieval) |
| veaReject | 2 | Reject the request implied by the event (reject the certificate, disallow the object retrieval) |
| veaAcceptNow | 3 | Accept the validated certificate immediately |
| veaAbortNow | 4 | Abort the validation, reject the certificate |

# DocumentLoaded Event ([PDFSigner](#pdfsigner-component) Component)

This event is fired when the document has been loaded into memory.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  bool Cancel;
} TsbxPDFSignerDocumentLoadedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerDocumentLoadedEvent)(System::TObject* Sender, TsbxPDFSignerDocumentLoadedEventParams *e);
__property TsbxPDFSignerDocumentLoadedEvent OnDocumentLoaded = { read=FOnDocumentLoaded, write=FOnDocumentLoaded };
```

## Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the Pages information to find the optimal position for the signature widget.

Set *Cancel* to true to terminate document processing on this stage.

# Encrypted Event ([PDFSigner](#pdfsigner-component) Component)

Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  bool CertUsed;
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  bool NeedCredential;
  bool SkipThis;
} TsbxPDFSignerEncryptedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerEncryptedEvent)(System::TObject* Sender, TsbxPDFSignerEncryptedEventParams *e);
__property TsbxPDFSignerEncryptedEvent OnEncrypted = { read=FOnEncrypted, write=FOnEncrypted };
```

## Remarks

The component fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.

This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the DecryptionCertificate or [Password](#password-property-pdfsigner-component) property (depending on the encryption method used), or sets *SkipThis* to true.

The *CertUsed* parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case, the *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own Encrypted event loop.

*CertUsed* set to false indicates that the document uses password encryption. In this case, provide the password via the [Password](#password-property-pdfsigner-component) property.

The *NeedCredential* parameter specifies whether the correct credential is already available to the component or still needs to be set. One example where *NeedCredential* would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the [Password](#password-property-pdfsigner-component) property to a known pre-defined value). If *NeedCredential* is set to true, you must provide the valid credential for the decryption process to succeed.

# Error Event ([PDFSigner](#pdfsigner-component) Component)

Information about errors during signing/validation.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int ErrorCode;
  String Description;
} TsbxPDFSignerErrorEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerErrorEvent)(System::TObject* Sender, TsbxPDFSignerErrorEventParams *e);
__property TsbxPDFSignerErrorEvent OnError = { read=FOnError, write=FOnError };
```

## Remarks

The event is fired in case of exceptional conditions during PDF processing.

*ErrorCode* contains an error code and *Description* contains a textual description of the error.

# ExternalDecrypt Event ([PDFSigner](#pdfsigner-component) Component)

Handles remote or external decryption.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String OperationId;
  String Algorithm;
  String Pars;
  String EncryptedData;
  String Data;
} TsbxPDFSignerExternalDecryptEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerExternalDecryptEvent)(System::TObject* Sender, TsbxPDFSignerExternalDecryptEventParams *e);
__property TsbxPDFSignerExternalDecryptEvent OnExternalDecrypt = { read=FOnExternalDecrypt, write=FOnExternalDecrypt };
```

## Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the *EncryptedData* parameter, and is expected to decrypt it and place the decrypted value into the *Data* parameter.

*OperationId* provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. *Algorithm* specifies the encryption algorithm being used, and *Pars* contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the *EncryptedData*, *Data*, and *Pars* parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

# ExternalSign Event ([PDFSigner](#pdfsigner-component) Component)

Handles remote or external signing initiated by the SignExternal method or other source.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String OperationId;
  String HashAlgorithm;
  String Pars;
  String Data;
  String SignedData;
} TsbxPDFSignerExternalSignEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerExternalSignEvent)(System::TObject* Sender, TsbxPDFSignerExternalSignEventParams *e);
__property TsbxPDFSignerExternalSignEvent OnExternalSign = { read=FOnExternalSign, write=FOnExternalSign };
```

## Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of *Data* to the signer, obtain the signature, and pass it back to the component via the *SignedData* parameter.

*OperationId* provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. *HashAlgorithm* specifies the hash algorithm being used for the operation, and *Pars* contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the *Data*, *SignedData*, and *Pars* parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following:

```text
signer.OnExternalSign += (s, e) =>
{
       var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable);
       var key = (RSACryptoServiceProvider)cert.PrivateKey;

       var dataToSign = e.Data.FromBase16String();
       var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1");
       e.SignedData = signedData.ToBase16String();
};
```

# Notification Event ([PDFSigner](#pdfsigner-component) Component)

This event notifies the application about an underlying control flow event.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String EventID;
  String EventParam;
} TsbxPDFSignerNotificationEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerNotificationEvent)(System::TObject* Sender, TsbxPDFSignerNotificationEventParams *e);
__property TsbxPDFSignerNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };
```

## Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the *EventID* parameter. *EventParam* contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

This component can fire this event with the following *EventID* values:

|  |  |
| --- | --- |
| DocumentLoaded | Reports the completion of PDF document processing by the component. Use the event handler to access document-related information, such as page number and document file details. The EventParam value passed with this EventID is empty. |
| BeforeTimestamp | This event is fired before a timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings. |
| TimestampError | This event is only fired if the component failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info. |
| TimestampRequest | A timestamp is requested from the custom timestamping authority. This event is only fired if [TimestampServer](#timestampserver-property-pdfsigner-component) was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to [TimestampServer](#timestampserver-property-pdfsigner-component)), in base16, that needs to be sent to the TSA. Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property. |
| BeforeDocumentTimestamp | This event is fired before adding document timestamp. Use the event handler to modify signature settings. |
| SignatureWidgetPrepare | Another copy of the signature widget needs to be configured. Use the event handler to configure individual widgets when creating multi-widget signatures. The Notification event with this event ID will be fired repeatedly until the [LastSignatureWidget](#LastSignatureWidget) configuration setting is set to true. The EventParam value passed with this EventID is empty. |
| SignaturesLoaded | Notifies the application that the component has finished loading signatures. |

# PreRenderWidget Event ([PDFSigner](#pdfsigner-component) Component)

Fires when a signature widget is ready to be written to the document.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  bool AddAnother;
  bool ResetAnother;
} TsbxPDFSignerPreRenderWidgetEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerPreRenderWidgetEvent)(System::TObject* Sender, TsbxPDFSignerPreRenderWidgetEventParams *e);
__property TsbxPDFSignerPreRenderWidgetEvent OnPreRenderWidget = { read=FOnPreRenderWidget, write=FOnPreRenderWidget };
```

## Remarks

The component fires this event when it is ready to insert a new instance of the signature widget to the document. This event is fired repeatedly until the event handler sets the *AddAnother* parameter to false, allowing your application to create as many copies of the signature widget as required.

You can use this event handler to adjust the look of each widget copy. Set the *ResetAnother* parameter to true to automatically clean up all the existing widget settings after the current widget is saved. Setting *ResetAnother* to true will let you start every new widget from scratch. Keeping it set to false would result in every new widget looking the same as the previous one.

# SignatureFound Event ([PDFSigner](#pdfsigner-component) Component)

Signifies the start of signature validation.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Index;
  String EntityLabel;
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  bool CertFound;
  bool ValidateSignature;
  bool ValidateChain;
} TsbxPDFSignerSignatureFoundEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerSignatureFoundEvent)(System::TObject* Sender, TsbxPDFSignerSignatureFoundEventParams *e);
__property TsbxPDFSignerSignatureFoundEvent OnSignatureFound = { read=FOnSignatureFound, write=FOnSignatureFound };
```

## Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters. It fires for every signature located in the verified document or message.

The *CertFound* parameter is set to True if the component has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the  and  properties respectively.

Use the *ValidateSignature* and *ValidateChain* parameters to tell the verifier which stages to include in the validation.

# SignatureValidated Event ([PDFSigner](#pdfsigner-component) Component)

Marks the completion of the signature validation routine.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Index;
  String EntityLabel;
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  int ValidationResult;
  bool Cancel;
} TsbxPDFSignerSignatureValidatedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerSignatureValidatedEvent)(System::TObject* Sender, TsbxPDFSignerSignatureValidatedEventParams *e);
__property TsbxPDFSignerSignatureValidatedEvent OnSignatureValidated = { read=FOnSignatureValidated, write=FOnSignatureValidated };
```

## Remarks

This event is fired upon the completion of the signature validation routine, and reports the respective validation result.

Use the *IssuerRDN*, *SerialNumber*, and/or *SubjectKeyID* parameters to identify the signing certificate.

*ValidationResult* is set to 0 if the validation has been successful, or to a non-zero value in case of a validation failure.

|  |  |  |
| --- | --- | --- |
| svtValid | 0 | The signature is valid |
| svtUnknown | 1 | Signature validity is unknown |
| svtCorrupted | 2 | The signature is corrupted |
| svtSignerNotFound | 3 | Failed to acquire the signing certificate. The signature cannot be validated. |
| svtFailure | 4 | General failure |
| svtReferenceCorrupted | 5 | Reference corrupted (XML-based signatures only) |

# TimestampFound Event ([PDFSigner](#pdfsigner-component) Component)

Signifies the start of a timestamp validation routine.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Index;
  String EntityLabel;
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  bool CertFound;
  bool ValidateTimestamp;
  bool ValidateChain;
} TsbxPDFSignerTimestampFoundEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTimestampFoundEvent)(System::TObject* Sender, TsbxPDFSignerTimestampFoundEventParams *e);
__property TsbxPDFSignerTimestampFoundEvent OnTimestampFound = { read=FOnTimestampFound, write=FOnTimestampFound };
```

## Remarks

This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters.

The *CertFound* parameter is set to True if the component has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the  and  properties respectively.

Use the *ValidateSignature* and *ValidateChain* parameters to tell the verifier which stages to include in the validation.

# TimestampRequest Event ([PDFSigner](#pdfsigner-component) Component)

Fires when the component is ready to request a timestamp from an external TSA.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String TSA;
  String TimestampRequest;
  String TimestampResponse;
  bool SuppressDefault;
} TsbxPDFSignerTimestampRequestEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTimestampRequestEvent)(System::TObject* Sender, TsbxPDFSignerTimestampRequestEventParams *e);
__property TsbxPDFSignerTimestampRequestEvent OnTimestampRequest = { read=FOnTimestampRequest, write=FOnTimestampRequest };
```

## Remarks

Subscribe to this event to intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.

The *TSA* parameter indicates the timestamping service being used. It matches the value passed to the [TimestampServer](#timestampserver-property-pdfsigner-component) property. Set the *SuppressDefault* parameter to true if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned *TimestampResponse* parameter is not empty.

# TimestampValidated Event ([PDFSigner](#pdfsigner-component) Component)

Reports the completion of the timestamp validation routine.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  int Index;
  String EntityLabel;
  String IssuerRDN;
  DynamicArray SerialNumber;
  DynamicArray SubjectKeyID;
  String Time;
  int ValidationResult;
  int ChainValidationResult;
  int ChainValidationDetails;
  bool Cancel;
} TsbxPDFSignerTimestampValidatedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTimestampValidatedEvent)(System::TObject* Sender, TsbxPDFSignerTimestampValidatedEventParams *e);
__property TsbxPDFSignerTimestampValidatedEvent OnTimestampValidated = { read=FOnTimestampValidated, write=FOnTimestampValidated };
```

## Remarks

This event is fired upon the completion of the timestamp validation routine, and reports the respective validation result.

*ValidationResult* is set to 0 if the validation has been successful, or to a non-zero value in case of a failure.

|  |  |  |
| --- | --- | --- |
| svtValid | 0 | The signature is valid |
| svtUnknown | 1 | Signature validity is unknown |
| svtCorrupted | 2 | The signature is corrupted |
| svtSignerNotFound | 3 | Failed to acquire the signing certificate. The signature cannot be validated. |
| svtFailure | 4 | General failure |
| svtReferenceCorrupted | 5 | Reference corrupted (XML-based signatures only) |

# TLSCertNeeded Event ([PDFSigner](#pdfsigner-component) Component)

Fires when a remote TLS party requests a client certificate.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String Host;
  String CANames;
} TsbxPDFSignerTLSCertNeededEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTLSCertNeededEvent)(System::TObject* Sender, TsbxPDFSignerTLSCertNeededEventParams *e);
__property TsbxPDFSignerTLSCertNeededEvent OnTLSCertNeeded = { read=FOnTLSCertNeeded, write=FOnTLSCertNeeded };
```

## Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The *Host* parameter identifies the host that makes a request, and the *CANames* parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the [TLSHandshake](#tlshandshake-event-pdfsigner-component) event for the given host and, if the certificate was accepted, succeeded by the [TLSEstablished](#tlsestablished-event-pdfsigner-component) event.

# TLSCertValidate Event ([PDFSigner](#pdfsigner-component) Component)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String ServerHost;
  String ServerIP;
  bool Accept;
} TsbxPDFSignerTLSCertValidateEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTLSCertValidateEvent)(System::TObject* Sender, TsbxPDFSignerTLSCertValidateEventParams *e);
__property TsbxPDFSignerTLSCertValidateEvent OnTLSCertValidate = { read=FOnTLSCertValidate, write=FOnTLSCertValidate };
```

## Remarks

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, components may contact a number of TLS endpoints during their work, depending on their configuration.

*Accept* is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.

# TLSEstablished Event ([PDFSigner](#pdfsigner-component) Component)

Fires when a TLS handshake with Host successfully completes.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String Host;
  String Version;
  String Ciphersuite;
  DynamicArray ConnectionId;
  bool Abort;
} TsbxPDFSignerTLSEstablishedEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTLSEstablishedEvent)(System::TObject* Sender, TsbxPDFSignerTLSEstablishedEventParams *e);
__property TsbxPDFSignerTLSEstablishedEvent OnTLSEstablished = { read=FOnTLSEstablished, write=FOnTLSEstablished };
```

## Remarks

The component uses this event to notify the application about a successful completion of a TLS handshake.

The *Version*, *Ciphersuite*, and *ConnectionId* parameters indicate the security parameters of the new connection. Use the *Abort* parameter if you need to terminate the connection at this stage.

# TLSHandshake Event ([PDFSigner](#pdfsigner-component) Component)

Fires when a new TLS handshake is initiated, before the handshake commences.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String Host;
  bool Abort;
} TsbxPDFSignerTLSHandshakeEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTLSHandshakeEvent)(System::TObject* Sender, TsbxPDFSignerTLSHandshakeEventParams *e);
__property TsbxPDFSignerTLSHandshakeEvent OnTLSHandshake = { read=FOnTLSHandshake, write=FOnTLSHandshake };
```

## Remarks

The component uses this event to notify the application about the start of a new TLS handshake to *Host*. If the handshake is successful, this event will be followed by the [TLSEstablished](#tlsestablished-event-pdfsigner-component) event. If the server chooses to request a client certificate, the [TLSCertNeeded](#tlscertneeded-event-pdfsigner-component) event will also be fired.

# TLSShutdown Event ([PDFSigner](#pdfsigner-component) Component)

Reports the graceful closure of a TLS connection.

## Syntax

*C++ Builder Syntax*

```text
typedef struct {
  String Host;
} TsbxPDFSignerTLSShutdownEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerTLSShutdownEvent)(System::TObject* Sender, TsbxPDFSignerTLSShutdownEventParams *e);
__property TsbxPDFSignerTLSShutdownEvent OnTLSShutdown = { read=FOnTLSShutdown, write=FOnTLSShutdown };
```

## Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

# Config Settings ([PDFSigner](#pdfsigner-component) Component)

 The component accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these *internal properties* is provided through the [Config](#config-method-pdfsigner-component) method.

### PDFSigner Config Settings

**AddOutputIntents**: Specifies output intents to be added to the document.Contains a comma-separated list of values that specify output intents that should be added to the document if they are not present.

Supported values are:

|  |  |  |
| --- | --- | --- |
| GTS_PDFA1.sRGB |  | GTS_PDFA1 corresponding to the PDF/A standard as defined by ISO 19005. sRGB IEC61966-2.1 is a standard color space. |
| GTS_PDFX.sRGB |  | GTS_PDFX corresponding to the PDF/X format standard specified in ISO 15930. sRGB IEC61966-2.1 is a standard color space. |

Output intents describe the final destination device you will use to reproduce the color in the PDF, such as the separations printing device. Output intents override working spaces during viewing and printing, but they do not convert the colors in the PDF.

**AlternateName**: TBD.TBD

**AssemblyOptions**: Specifies the assembly options.Contains a comma-separated list of values that specify the assembly options of the PDF document.

Supported values are:

|  |  |  |
| --- | --- | --- |
| AcrobatFriendlyAcroForm |  | Acrobat reader friendly form |
| AdjustTimesToUTC |  | Asserts that all the time properties are set in local time and should be adjusted to UTC when writing to the document |

**AsyncDocumentID**: Specifies the document ID for SignAsyncEnd() call.Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch.

Set this property to *True* to update the structure tree and to *False* to leave it unchanged.

This setting only makes sense for documents that already contain a *StructTreeRoot* entry. If this property is not set explicitly, the component may enable it automatically for loaded tagged PDF documents that do not yet contain signatures.

**BackgroundImageBitsPerComponent**: Specifies the number of bits per color component.Specifies the number of bits per color space component for the background image.

The default value is 0, which means that BitsPerComponent is set automatically according to the widget's  property.

**BackgroundImageColorSpace**: Specifies the background image color space.Specifies the background image color space.

Supported values are:

|  |  |  |
| --- | --- | --- |
| "" |  | The default value is empty string or "none". If the widget's [](#f_BackgroundImageType) field is JPEG or Custom, then the default value is "RGB". |

      "PreRelease":true,
      "NonEFontNoWarn":true
   }
}
```

**CachedCRLMaxAge**: Specifies the maximum age of a cached CRL.Use this setting to specify the maximum number of seconds that may pass since a CRL was added to the global cache. When the cached CRL is older than this value, it is disregarded and a new CRL should be fetched.

The default value is 10 minutes (600 seconds). A value of 0 disables the CRL overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from [CachedCRLMaxAge](#CachedCRLMaxAge) and [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio). If several cached CRL freshness settings are enabled, the cached CRL is used only if it satisfies all of them.

**CachedOCSPResponseMaxAge**: Specifies the maximum age of a cached OCSP response.Use this setting to specify the maximum number of seconds that may pass since an OCSP response was added to the global cache. When the cached OCSP response is older than this value, it is disregarded and a new OCSP response should be fetched.

The default value is 1 hour (3600 seconds). A value of 0 disables the absolute OCSP response age check. This setting is also used to limit open-ended OCSP responses that do not have NextUpdate. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseMaxAgeRatio**: Specifies the maximum age of a cached OCSP response as a percentage of its remaining lifetime.Use this setting to specify the percentage of the OCSP response's remaining lifetime, measured from the time the OCSP response was added to the global cache to the response's NextUpdate. When this portion of the remaining lifetime has passed, the cached OCSP response is disregarded and a new OCSP response should be fetched.

The default value is 50 percent. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) to limit their age. A value of 0 disables the OCSP response ratio check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseOverlapTime**: Specifies the time period before a cached OCSP response's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached OCSP response should be disregarded, and a new OCSP response should be fetched.

The default value is 10 minutes (600 seconds). A value of 0 disables the OCSP response overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio). If several cached OCSP response freshness settings are enabled, the cached OCSP response is used only if it satisfies all of them.

**CheckValidityPeriodForTrusted**: Whether to check validity period for trusted certificates.Whether to check validity period for trusted certificates.

**CollectRevInfoForTimestamps**: Whether revocation info for timestamps should be collected automatically.Specifies whether revocation info for timestamps should be collected automatically.

This property enables collection of revocation info for any new ("fresh") timestamps, that are created during the current operation, such as signing or updating a signature with a document timestamp.

Note that revocation info for existing timestamps is always collected when updating the signature that contains them, regardless of this setting.

**Commitments**: TBD.TBD

**ConfigPreferLegacyLevels**: Indicates whether legacy signature levels should be preferred.Set this property to True to instruct the validation engine to prioritize legacy PAdES signature levels (BES, EPES, LTV) over Baseline levels (B-B, B-T, B-LT, B-LTA) when a signature can be determined as multiple levels.

**DeepValidation**: Whether a complete validation should be performed.If this property is switched on, a "deep" signature validation is performed, i.e., all certificate chains are validated, and all revocation checks are performed.

**DeltaCRLPreference**: Specifies whether complete or delta CRLs are preferred.Use this setting to specify which CRL type should be preferred during revocation checks performed by the AdES component.

The default value is **dcrlpPreferComplete** (1).

Supported values:

- **dcrlpPreferDelta** (0): retrieve and use delta CRLs when available, falling back to complete CRLs when needed.
- **dcrlpPreferComplete** (1): try complete CRLs first, and use delta CRLs only if complete CRLs cannot be retrieved.

**DislikeOpenEndedOCSPs**: Tells the component to discourage OCSP responses without an explicit NextUpdate parameter.When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the component is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022).

**DocumentVersion**: The document version from the PDF document header.This property contains the PDF document version provided in the document header. The version is returned in the form "Major.Minor": for example, PDF-1.7 will be returned as "1.7", and PDF-2.0 as "2.0".

**DTSAccuracy**: Indicates the accuracy of the document timestamp.Use this property to get the accuracy of the document timestamp in microseconds.

The value is set for document timestamp signatures and is 0 if the timestamp does not include accuracy information.

Signatures of this kind are very old, insecure, and extremely rarely used. It is reasonable to only enable this setting if you are know what you are doing.

**EncryptionHandlerName**: Specifies the custom security handler PDF-name.Specifies the custom security handler PDF-name for the encryption handler.

**EvaluateSystemTrust**: Enables or disables usage of the platform's built-in trust validation facilities.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is disabled by default, because enabling it may prevent the AdES components from collecting full revocation information required for long-term validation (LTV) signatures.

**EvaluateSystemTrustForSelfSignedCertificates**: Enables or disables usage of the platform's built-in trust validation facilities for self-signed certificates.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) for self-signed certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**EvaluateSystemTrustForSSL**: Enables or disables usage of the platform's built-in trust validation facilities for SSL/TLS.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) specifically for SSL/TLS certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**ExtensionIdentifierMode**: Specifies the extension identifier mode.Specifies the extension modifier mode that controls which Extension Level should be added to the PDF document while signing.

Supported values are:

|  |  |  |
| --- | --- | --- |
| none |  | No extensions |
| ESIC |  | ESIC Extension Level 2 |
| ADBE |  | Adobe Extension Level 8 |
| ADBEIfNotPresent |  | Adobe Extension Level 8 if not present |
| Both |  | Both (ESIC and Adobe) extensions |

**ExtraSpace**: Allows for the allocation of extra zero character space in the document behind the signature.Use this property to allocate extra zero character space in the document behind the signature. The allocated space can be used in the future to place a timestamp.

**FontPaths**: Specifies font search paths.Use this property to provide a CRLF-separated list of directories where TrueType font files should be searched. This setting is used when resolving a TrueType font specified in the  field without a full file path.

Each entry is interpreted as a directory path used during font lookup. To use a specific TrueType font file, specify its file name and include the containing directory in this setting, or specify the full file path in the  field.

The default value is the system font search paths. These paths are platform-dependent:

|  |  |
| --- | --- |
| Windows | %windir%\Fonts and %LOCALAPPDATA%\Microsoft\Windows\Fonts. |
| macOS | /System/Library/Fonts/, /Library/Fonts/, and ~/Library/Fonts/. |
| iOS | /System/Library/Fonts/, /Library/Fonts/, and ~/Library/Fonts/. |
| Linux | Directories listed by dir entries in /etc/fonts/fonts.conf and /usr/local/etc/fonts/fonts.conf. |
| Android | /system/fonts. |

On Windows, .NET and Java editions obtain these locations through the runtime APIs or the *windir*, *SystemRoot*, and *LOCALAPPDATA* environment variables.

Assigning this setting replaces the current search path list. To use custom directories together with the default system locations, include both in the assigned value.

**ForceCompleteChainValidation**: Whether to check the CA certificates when the signing certificate is invalid.Set this property to True to check issuer (CA) certificates if the signing or an intermediate chain certificate is invalid.

**ForceCompleteChainValidationForTrusted**: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors. Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

**GracePeriod**: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated.

**HardenedKeyGeneration**: Specifies if hardened Key generation should be used.Specifies if hardened Key generation should be used when the AES-256 encryption algorithm and password encryption are used.

**IgnoreChainLoops**: Whether chain loops should be ignored.Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves.

**IgnoreChainValidationErrors**: Whether to ignore any certificate chain validation issues.Enable this property to ignore any chain validation errors when creating a signature. This may be useful if the signature is created in an environment which uses different trust settings to the validation environment.

**IgnoreOCSPNoCheckExtension**: Whether the OCSP NoCheck extension should be ignored.Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues.

**IgnoreSystemTrust**: Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component should trust the certificates residing in the Trusted Root Certification Authorities store.

If [IgnoreSystemTrust](#IgnoreSystemTrust) is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the TrustedCertificates property) are considered trusted.

**IgnoreTimestampChainValidityForLevelDetection**: Specify whether timestamp chain validity should be ignored during signature level detection.Set this property to True to instruct the validation engine to disregard the validity of the timestamp signer certificate chain when determining the signature level.

TBD

**IgnoreTimestampFailure**: Whether to ignore timestamping failures during signing.Specifies whether to ignore timestamping failures during signing.

**ImplicitlyTrustSelfSignedCertificates**: Whether to trust self-signed certificates. Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows emulating the verifying environment without actually changing its security settings.

**IncludeKnownRevInfoToSignature**: Whether to include custom revocation info into the signature.This property specifies whether revocation pieces provided via the KnownCertificates, KnownCRLs, and KnownOCSPs properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

Note: it makes sense to disable [AutoCollectRevocationInfo](#AutoCollectRevocationInfo) property when using this property. TBD equals to IncludeKnownRevocationInfoToSignature

**IncludeKnownRevocationInfoToSignature**: Whether to include custom revocation info into the signature.This property specifies whether revocation pieces provided via the KnownCertificates, KnownCRLs, and KnownOCSPs properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

Note: it makes sense to disable [AutoCollectRevocationInfo](#AutoCollectRevocationInfo) property when using this property.

**IncludeRevocationInfo**: Whether to include custom revocation info into the signature.This property specifies whether revocation pieces provided via the KnownCertificates, KnownCRLs, and KnownOCSPs properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

Note: it makes sense to disable [AutoCollectRevocationInfo](#AutoCollectRevocationInfo) property when using this property. TBD equals to IncludeKnownRevocationInfoToSignature

**IncludeRevocationInfoToAdbeAttribute**: Whether to save revocation info in PDF-compliant form.The format of revocation info in AdES signatures does not comply with PDF standards. If this property is switched on, the revocation info will be saved in PDF-compliant form.

**IsLTVEnabled**: Indicates LTV-enabled signature.Use this property to check if the signature is *LTV-enabled*. This property is similar to *LTV-enabled* property reported by Adobe Reader.

This is a signature property that can be accessed as "Signatures[index].IsLTVEnabled", or as "IsLTVEnabled" for the current signature (the signature being validated or the last signature).

**LastSignatureWidget**: Specifies that it is the last signature widget to be added.Set this property to False to add one more signature widget along with the signature.

This setting is used by the [Notification](#notification-event-pdfsigner-component) event when the *EventID* parameter is "SignatureWidgetPrepare" to allow support for multi-widget signatures.

**Locked**: TBD.TBD

**LockedContents**: TBD.TBD

**MappingName**: TBD.TBD

**MDPHashAlgorithm**: Specifies the MDP hash algorithm.Use this property to control the hash algorithm's signature references (DocMDP, FieldMDP transforms).

The following values are supported:

|  |  |  |

|  | "SHA512" | The component uses SHA512 hash algorithm. |
|  | "RIPEMD160" | The component uses RIPEMD160 hash algorithm. |
|  | "SHA3_256" | The component uses SHA3-256 hash algorithm. |
|  | "SHA3_384" | The component uses SHA3-384 hash algorithm. |
|  | "SHA3_512" | The component uses SHA3-512 hash algorithm. |
|  | "SHAKE_256" | The component uses SHAKE-256 hash algorithm. |
|  | "none" | The component will not calculate a digest and will not include DigestLocation, DigestMethod, and DigestValue keys of the Signature References dictionary. |

| IncludeAllRevInfoToDSS |  | When this flag is set, the full set of revocation information will be included in the DSS dictionary. |
| CreateVRIDictionaries |  | When this flag is set, VRI dictionaries will be created. A VRI dictionary references all the validation data that has been used for validating one specific signature. |
| UseUndefBEREncoding |  | When this flag is set, ASN.1 tags with undefined sizes are allowed in the signature. |
| TolerateMissingSigningCertificate |  | When this flag is set, a missing signing certificate attribute will be tolerated. |
| CompressDSS |  | When this flag is set, content in DSS dictionary will be compressed. |
| CreatePBADCompatibleSignature |  | When this flag is set, the PBAD.PAdES compatible signature is created. |
| EnforcePDFACompliance |  | When this flag is set, the component will enforce PDF/A compliance during signing. In rare cases this may lead to exceptions being thrown if the signing chain is too heavy to fit into the PDF/A restrictions. |

**PageInfoCount**: The number of pages.Returns the number of pages available.

The following values are supported:

|  |  |  |
| --- | --- | --- |
|  | "auto" | Default value. The component automatically reassembles PDF documents in case they contain errors that may invalidate new signatures. |
|  | "disabled" | The component never reassembles PDF documents. This value is not recommended. |
|  | "enabled" | The component always reassembles PDF documents. |

Supported values are case-insensitive:

|  |  |
| --- | --- |
| Default | Applies the AdES default freshness settings: crl:86400;50;600,ocsp:3600;50;600. This means: CRL maximum age 1 day, CRL age ratio 50%, CRL overlap 10 minutes; OCSP response maximum age 1 hour, OCSP response age ratio 50%, OCSP response overlap 10 minutes. This value is the default. |
| Disabled | Sets [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) to 0. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache. |
| Short | Uses crl:43200;50;300,ocsp:1800;50;300. This means: CRL maximum age 12 hours, CRL age ratio 50%, CRL overlap 5 minutes; OCSP response maximum age 30 minutes, OCSP response age ratio 50%, OCSP response overlap 5 minutes. |
| Long | Uses crl:518400;50;3600,ocsp:21600;50;3600. This means: CRL maximum age 6 days, CRL age ratio 50%, CRL overlap 1 hour; OCSP response maximum age 6 hours, OCSP response age ratio 50%, OCSP response overlap 1 hour. |
| N | Interprets N as an integer number of seconds. The overlap settings are set to N seconds, CRL maximum age is set to N * 144, OCSP response maximum age is set to N * 6, and both ratio settings are set to 50. |
| crl:<maxAge>;<ratio>;<overlap>,ocsp:<maxAge>;<ratio>;<overlap> | Sets the CRL and OCSP response freshness values explicitly. |

Ratios must be in the 0..100 range. Maximum age and overlap values must be non-negative. Short and Long are time-scale profiles: Long allows older cached revocation information by increasing maximum ages, but also uses a larger pre-expiry safety margin by increasing overlap times. For individual [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) settings, a value of 0 disables the corresponding freshness check.

It also seals the added elements with a Document Timestamp if the TSA is provided through the [TimestampServer](#timestampserver-property-pdfsigner-component) property.

The only alternative setting is *TimestampOnly*, which instructs Update() to only timestamp the updated non-timestamped signature with a signature timestamp. No validation information collection is performed and no Document Timestamp is added. The *TimestampOnly* variant requires the [TimestampServer](#timestampserver-property-pdfsigner-component) property to be set.

**UseArabicLigature**: Specifies whether to use Arabic ligatures.Set this property to True to enable Arabic ligatures in the signature widget. When enabled, certain adjacent Arabic characters may be combined and rendered as a single ligature form (where supported by the shaping engine/font), improving the natural appearance of the text.

When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

**UseInternalRandom**: Switches between SecureBlackbox-own and platform PRNGs.Allows to switch between internal/native PRNG implementation and the one provided by the platform.

**UseLegacyAdESValidation**: Enables legacy AdES validation mode.Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

**UseSystemOAEPAndPSS**: Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:

```text
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
```

Where:

OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.

PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.

Alias1, Alias2, ...: Optional alternative names recognized during parsing.

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

```text
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
```

Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:

```text
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
```

**XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

**XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).

**XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
