## Remarks

Use PDFVerifier to validate electronic signatures over PDF documents. Generic and PAdES signatures are supported.

```text
PDFVerifier verifier = new PDFVerifier();

// Set the signed PDF document that you want to verify
verifier.setInputFile("signed.pdf");

verifier.verify();

// Verification information
for (int idx = 0; idx < verifier.getSignatures().size(); idx++) {
  System.out.println("Signature " + (idx + 1));
  System.out.println("  Timestamp:         " + verifier.getSignatures().item(idx).getValidatedSigningTime());

  System.out.print("  Validation Result: " + verifier.getSignatures().item(idx).getSignatureValidationResult() + ", ");
  switch (verifier.getSignatures().item(idx).getSignatureValidationResult()) {
    case svtValid:
      System.out.println("The signature is valid.");
      break;
    case svtUnknown:
      System.out.println("Signature validity is unknown.");
      break;
    case svtCorrupted:
      System.out.println("The signature is corrupted.");
      break;
    case svtSignerNotFound:
      System.out.println("Failed to acquire the signing certificate. The signature cannot be validated.");
      break;
    case svtFailure:
      System.out.println("General failure.");
      break;
    default:
      System.out.println("Signature validity is unknown.");
      break;
  }
}
```

PDFVerifier validates each signature from two perspectives: the integrity and validity of the signature itself (i.e. its correspondence to the document data it covers), and the validity and trustworthiness of the signing certificate chain. These two signature aspects are generally independent of each other: the signature may be valid but the chain may not be trusted, or the other way around, the chain may be trusted but the integrity of the signature may be violated. Under normal circumstances both the signature **and** the chain must be valid for the signature to be considered good.

To initiate the validation, assign the path to the signed PDF file to the [InputFile](#inputfile-property-secureblackbox_pdfverifier-class) property (alternatively, you can provide it in a memory buffer via the [InputBytes](#inputbytes-property-secureblackbox_pdfverifier-class) property), and call the [Verify](#verify-method-secureblackbox_pdfverifier-class) method. For every signature located in the document, PDFVerifier will fire the [SignatureFound](#signaturefound-event-secureblackbox_pdfverifier-class) event. This event lets you specify whether you want PDFVerifier to validate the signature, the chain, or both.

Note: it does not mean that any of the two is optional. This API lets you be flexible in how you validate documents in your code in accordance with the specifics of your application and its usage scenarios. For example, if your trust environment relies on certificate pinning, validating the chain by PDFVerifier internally may cause unnecessary burden on the system, in which case it may be reasonable to disable it in the event handler.

Once [SignatureFound](#signaturefound-event-secureblackbox_pdfverifier-class) returns, PDFVerifier proceeds to the signature validation routine in accordance with the provided settings. Upon completion of the validation, the [SignatureValidated](#signaturevalidated-event-secureblackbox_pdfverifier-class) event is fired, and the validation results are separately provided via the  and  fields of the associated signature object. Other information about the signature can be accessed via the Signatures property.

The PDF format uses incremental updates to introduce changes to the document. This implies that a signature may cover not the whole document, but rather a certain revision of it. Strictly speaking, every signature in a PDF document, apart from perhaps the last one, covers just some part of the document. In most cases that part matches the revision of the document that existed before all the subsequent signatures had been added.

Because of these specifics of the PDF format, it is crucially important to understand which part of the document is covered by a specific signature. Use the  field to establish the scope of a signature. The revision of the document covered by that specific signature ranges from byte 0 to CoverageEndsAt. Alternatively, you can use the [GetSignedVersion](#getsignedversion-method-secureblackbox_pdfverifier-class) method to extract the signed revision to a file.

### Useful settings and properties

The following properties of PDFVerifier may be handy when working with this class:

- [OfflineMode](#offlinemode-property-secureblackbox_pdfverifier-class) lets you validate the document without contacting online revocation sources. Paired with switched-off system trust settings, it can be used to establish the long-term validity of the document and the completeness of the validation material included in it.
- [RevocationCheck](#revocationcheck-property-secureblackbox_pdfverifier-class) lets you adjust the revocation checking preferences.
-  returns the signing time as recorded in the embedded signature timestamp. This is in contrast to , which returns the signing time as specified by the signer.
-  is a great way to find out the details of chain validation failures. This property returns a comprehensive validation log that reports all the issues encountered during the validation.
- If the document is encrypted (in addition to being signed), the [Encrypted](#encrypted-event-secureblackbox_pdfverifier-class) event will fire, asking you for the decryption certificate or password.

By default, PDFVerifier uses the system trust settings to establish certificate chain validity. You can configure it to use your own, custom validation environment by providing the necessary trust elements via KnownCertificates, TrustedCertificates, KnownCRLs, and other similar properties.

```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 58 , $certindex);
```

## 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-secureblackbox_pdfverifier-class) 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-secureblackbox_pdfverifier-class) property.

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

```

## Default Value

0

## 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) class 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-secureblackbox_pdfverifier-class) property.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# CertFingerprint Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Contains the fingerprint (a hash imprint) of this certificate.

## Object Oriented Interface

```text
public function getCertFingerprint($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 62 , $certindex);
```

## Default Value

''

## Remarks

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# CertFriendlyName Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Contains an associated alias (friendly name) of the certificate.

## Object Oriented Interface

```text
public function getCertFriendlyName($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 63 , $certindex);
```

## Default Value

''

## Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# CertHandle Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function getCertHandle($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 64 , $certindex);
```

## 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 *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

Long64

# CertHashAlgorithm Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Object Oriented Interface

```text
public function getCertHashAlgorithm($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 65 , $certindex);
```

## Default Value

''

## Remarks

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use [CertSigAlgorithm](#certsigalgorithm-property-secureblackbox_pdfverifier-class) to find out the hash algorithm that is part of the certificate signature.

Use the [CertKeyBits](#certkeybits-property-secureblackbox_pdfverifier-class), [CertCurve](#certcurve-property-secureblackbox_pdfverifier-class), and [CertPublicKeyBytes](#certpublickeybytes-property-secureblackbox_pdfverifier-class) properties to get more details about the key the certificate contains.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# CertKeyBits Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns the length of the public key in bits.

## Object Oriented Interface

```text
public function getCertKeyBits($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 69 , $certindex);
```

## Default Value

0

## Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the [CertPublicKeyBytes](#certpublickeybytes-property-secureblackbox_pdfverifier-class) or [CertPrivateKeyBytes](#certprivatekeybytes-property-secureblackbox_pdfverifier-class) property would typically contain auxiliary values, and therefore be longer.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

Integer

# CertKeyFingerprint Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns a SHA1 fingerprint of the public key contained in the certificate.

## Object Oriented Interface

```text
public function getCertKeyFingerprint($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 70 , $certindex);
```

## Default Value

''

## Remarks

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the [CertFingerprint](#certfingerprint-property-secureblackbox_pdfverifier-class) property. The key fingerprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

The *$certindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# CertKeyUsage Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

## Object Oriented Interface

```text
public function getCertKeyUsage($certindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 71 , $certindex);
```

## Default Value

0

## Remarks

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

```

## Default Value

## 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.

secureblackbox_pdfverifier_get($res, 262 , $signatureindex);
```

## Possible Values

```text
PDFVERIFIER_SIGNATURECHAINVALIDATIONRESULT_VALID(0), PDFVERIFIER_SIGNATURECHAINVALIDATIONRESULT_VALID_BUT_UNTRUSTED(1), PDFVERIFIER_SIGNATURECHAINVALIDATIONRESULT_INVALID(2), PDFVERIFIER_SIGNATURECHAINVALIDATIONRESULT_CANT_BE_ESTABLISHED(3)
```

## Default Value

0

## 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 *$signatureindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

Integer

# SignatureClaimedSigningTime Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns or sets the signature's creation time.

## Object Oriented Interface

```text
public function getSignatureClaimedSigningTime($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 263 , $signatureindex);
```

## 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-secureblackbox_pdfverifier-class), 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-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

# SignatureCompatibilityErrors Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns compatibility errors encountered during validation.

## Object Oriented Interface

```text
public function getSignatureCompatibilityErrors($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 264 , $signatureindex);
```

## 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-secureblackbox_pdfverifier-class) property.

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

## Data Type

Integer

# SignatureContactInfo Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Contains the signer's contact information.

## Object Oriented Interface

```text
public function getSignatureContactInfo($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 265 , $signatureindex);
```

## Default Value

''

## Remarks

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

The *$signatureindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [SignatureCount](#signaturecount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

String

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

## Object Oriented Interface

```text
public function getSignatureContainsLongTermInfo($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 266 , $signatureindex);

# SignatureCoverageEndsAt Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function getSignatureCoverageEndsAt($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 267 , $signatureindex);
```

## 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](#getsignedversion-method-secureblackbox_pdfverifier-class) method of the PDFVerifier class 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-secureblackbox_pdfverifier-class) property.

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

## Data Type

Integer

# SignatureCustomData Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Uninterpreted custom data to save with the PDF signature.

## Object Oriented Interface

```text
public function getSignatureCustomData($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 268 , $signatureindex);
```

## 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-secureblackbox_pdfverifier-class) property.

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

# SignatureEmptyField Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function getSignatureEmptyField($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 269 , $signatureindex);
```

## 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-secureblackbox_pdfverifier-class) property.

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

# SignatureFilterName Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function getSignatureFilterName($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 271 , $signatureindex);
```

## 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-secureblackbox_pdfverifier-class) property.

```text
public function getSignatureHandle($signatureindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 273 , $signatureindex);
```

## 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());
```

```

## Default Value

2

## 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-secureblackbox_pdfverifier-class), [SignaturePolicyHashAlgorithm](#signaturepolicyhashalgorithm-property-secureblackbox_pdfverifier-class), and [SignaturePolicyHash](#signaturepolicyhash-property-secureblackbox_pdfverifier-class).

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

1

## 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.

public function getTrustedCertCount();
public function setTrustedCertCount($value);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 422 );
secureblackbox_pdfverifier_set($res, 422, $value );
```

## Default Value

0

## Remarks

This property controls the size of the following arrays:

- [TrustedCertBytes](#trustedcertbytes-property-secureblackbox_pdfverifier-class)
- [TrustedCertHandle](#trustedcerthandle-property-secureblackbox_pdfverifier-class)

The array indices start at *0* and end at *TrustedCertCount - 1*.

This property is not available at design time.

## Data Type

Integer

# TrustedCertBytes Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns the raw certificate data in DER format.

## Object Oriented Interface

```text
public function getTrustedCertBytes($trustedcertindex);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 423 , $trustedcertindex);
```

## Remarks

Returns the raw certificate data in DER format.

The *$trustedcertindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-secureblackbox_pdfverifier-class) property.

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

## Data Type

Byte Array

# TrustedCertHandle Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function getTrustedCertHandle($trustedcertindex);
public function setTrustedCertHandle($trustedcertindex, $value);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 431 , $trustedcertindex);
secureblackbox_pdfverifier_set($res, 431, $value , $trustedcertindex);
```

## 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 *$trustedcertindex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-secureblackbox_pdfverifier-class) property.

This property is not available at design time.

## Data Type

Long64

# ValidationMoment Property ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

The time point at which signature validity is to be established.

## Object Oriented Interface

```text
public function getValidationMoment();
public function setValidationMoment($value);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_get($res, 462 );
secureblackbox_pdfverifier_set($res, 462, $value );
```

## Default Value

''

## Remarks

Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either the signature creation time or the current time).

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

## Data Type

String

# Close Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Closes an opened document.

## Object Oriented Interface

```text
public function doClose($savechanges);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_close($res, $savechanges);
```

## Remarks

Use this method to close a previously opened document. The *SaveChanges* parameter is only taken into account if the document was opened in edit mode.

# Config Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Sets or retrieves a configuration setting.

## Object Oriented Interface

```text
public function doConfig($configurationstring);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_config($res, $configurationstring);
```

## Remarks

Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-pdfverifier-class) for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-pdfverifier-class), you must call *Config("PROPERTY")*. The value will be returned as a string.

# DoAction Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Performs an additional action.

## Object Oriented Interface

```text
public function doDoAction($actionid, $actionparams);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_doaction($res, $actionid, $actionparams);
```

## Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the *ActionID* parameter.

*ActionParams* contains the value of a single parameter, or a list of multiple parameters for the action in the form of *PARAM1=VALUE1;PARAM2=VALUE2;...*.

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |
| ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |
| ResetCertificateCache | none | none | Clears the cached certificates. |
| ResetCRLCache | none | none | Clears the cached CRLs. |
| ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. |

# GetAttachedBytes Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Saves a PDF attachment to a byte array.

## Object Oriented Interface

```text
public function doGetAttachedBytes($index);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_getattachedbytes($res, $index);
```

## Remarks

Use this method to retrieve the contents of an attached file as a byte array.

# GetAttachedFile Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Saves a PDF attachment to a file.

## Object Oriented Interface

```text
public function doGetAttachedFile($index, $path);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_getattachedfile($res, $index, $path);
```

## Remarks

Use this method to retrieve the contents of an attached file and save it to a file.

# GetSignedVersion Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Returns the part of the document that is covered by the signature.

## Object Oriented Interface

```text
public function doGetSignedVersion($siglabel);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_getsignedversion($res, $siglabel);
```

## Remarks

Use this method to retrieve the revision of the document that is covered by the *SigLabel* signature.

PDF documents often use the incremental updates approach, with any changes being appended to the document without altering the existing revision. This may lead to situations where a signature only covers a part of the document (one of the past revisions), but not the subsequent changes. This method provides means to extract the revision that is actually certified by the signature.

It is recommended that you use this method when validating signatures to make sure the signature covers what you expect it to cover.

An alternative to this method is to check the  field of the signature object and match it to the document length.

# Open Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Opens a document for verifying or removing signatures.

## Object Oriented Interface

```text
public function doOpen($editmode);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_open($res, $editmode);
```

## Remarks

Use this method to open a document for verifying or removing signatures, or for extracting signed content. When finished, call [Close](#close-method-secureblackbox_pdfverifier-class) to complete the operation and release any allocated resources.

Set *EditMode* to true to open the document in edit mode (only useful if you intend to remove signatures).

# Reset Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Resets the class settings.

## Object Oriented Interface

```text
public function doReset();
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_reset($res);
```

## Remarks

Reset is a generic method available in every class.

# Revalidate Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Revalidates a signature in accordance with current settings.

## Object Oriented Interface

```text
public function doRevalidate($siglabel);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_revalidate($res, $siglabel);
```

## Remarks

Use this method to revalidate a signature in the opened PDF document.

# SelectInfo Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Select signature information for a specific entity.

## Object Oriented Interface

```text
public function doSelectInfo($entitylabel, $infotype, $clearselection);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_selectinfo($res, $entitylabel, $infotype, $clearselection);
```

## Remarks

Use this method to select (or filter) signature-related information for a specific signature element.

Provide the unique label of the entity that you are interested in via the *EntityLabel* parameter. Use one of the following filters, or their combination, to specify what information you are interested in:

|  |  |  |
| --- | --- | --- |
| sitEntity | 1 | Select the current entity |
| sitParentEntity | 2 | Select the parent entity of the current entity |
| sitTimestamps | 4 | Select all timestamps covering the current entity |
| sitSignatures | 8 | Select all signatures covering the current entity |
| sitSigningChain | 16 | Select the signing chain of the current entity |
| sitEmbeddedCertificates | 256 | Select all certificates embedded in the current entity |
| sitEmbeddedCRLs | 512 | Select all CRLs embedded in the current entity |
| sitEmbeddedOCSPs | 1024 | Select all OCSP responses embedded in the current entity |
| sitEmbeddedRevInfo | 1792 | Select the whole pack of embedded revocation information (certificates, CRLs and OCSPs) |
| sitUsedCertificates | 4096 | Select all the certificates used to validate this entity's chain |
| sitUsedCRLs | 8192 | Select all the CRLs used to validate this entity's chain |
| sitUsedOCSPs | 16384 | Select all the OCSP responses used to validate this entity's chain |
| sitUsedRevInfo | 28672 | Select the whole pack of revocation information used to validate this entity's chain (certificates, CRLs, OCSP responses) |
| sitAttributes | 65536 | Select this entity's CMS attributes |
| sitReferences | 131072 | Select this entity's XML references |
| sitSignedParts | 262144 | Select this entity's signed parts |

Following the call, the relevant pieces of information will be copied to the respective component properties (Certificates, CRLs, OCSPs). Note that you can accumulate information in the properties by making repeated calls to SelectInfo and keeping *ClearSelection* set to false.

This method is useful if you would like to read/display detailed information about a particular signature or timestamp.

# Unsign Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Deletes a signature from the document.

## Object Oriented Interface

```text
public function doUnsign($siglabel, $unsignkind);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_unsign($res, $siglabel, $unsignkind);
```

## Remarks

Use this method to delete an existing signature from the document. Use the *SigLabel* parameter to specify the signature to be removed.

Unsigning is different from [GetSignedVersion](#getsignedversion-method-secureblackbox_pdfverifier-class). The latter returns the revision of the document *including* the mentioned signature (thus removing anything added after that signature was created). Unsign removes the signature completely by carving it out of the document.

For multi-signature documents, the Unsign method removes the signature by marking its objects as removed in a new incremental update. A deleted signature might be present in the signature panel in Adobe as the deleted signature. If, for example, in the multi-signature document the last signature should be removed without any trace of the last signature, then [GetSignedVersion](#getsignedversion-method-secureblackbox_pdfverifier-class) method should be used.

The following unsign kinds are currently supported:

|  |  |
| --- | --- |
| uskDefault (0) | The default option. |
| uskFull (1) | Remove the signature fully. This is also the default option. |
| uskKeepField (2) | Only remove the signature, but keep the form field it is in. |
| uskKeepAppearance (3) | Remove the signature, but keep the form field and its widget. |

Note: *SigLabel* set to "" removes all signatures in the document.

# Verify Method ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Verifies a signed PDF document.

## Object Oriented Interface

```text
public function doVerify();
```

## Procedural Interface

```text
secureblackbox_pdfverifier_do_verify($res);
```

## Remarks

Use this method to validate all signatures in a PDF document.

This method walks through a signed document and reports every signature via the [SignatureFound](#signaturefound-event-secureblackbox_pdfverifier-class) event. Subscribe to the event to be notified about the signatures and adjust validation settings on the fly.

Upon completion of this method, the signature details will be published in the Signatures property.

This method only validates the signatures, but does not check their coverage. It is a good idea to use mechanisms such as [GetSignedVersion](#getsignedversion-method-secureblackbox_pdfverifier-class) or  to ensure that the signature covers the expected document revision.

# ChainElementDownload Event ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function fireChainElementDownload($param);
```

## Procedural Interface

secureblackbox_pdfverifier_register_callback($res, 1, array($this, 'fireChainElementDownload'));
```

## Parameter List

```text
 'kind' 'certrdn' 'cacertrdn' 'location' 'action'
```

## Remarks

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

|  |  |  |
| --- | --- | --- |
| 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) |

# ChainValidationProgress Event ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function fireChainValidationProgress($param);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_register_callback($res, 4, array($this, 'fireChainValidationProgress'));
```

## Parameter List

```text
 'eventkind' 'certrdn' 'cacertrdn' 'action'
```

## 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) |

| veaAcceptNow | 3 | Accept the validated certificate immediately |
| veaAbortNow | 4 | Abort the validation, reject the certificate |

# DocumentLoaded Event ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function fireDocumentLoaded($param);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_register_callback($res, 5, array($this, 'fireDocumentLoaded'));
```

## Parameter List

```text
 'cancel'
```

## 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 ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

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

## Object Oriented Interface

```text
public function fireEncrypted($param);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_register_callback($res, 6, array($this, 'fireEncrypted'));
```

## Parameter List

```text
 'certused' 'issuerrdn' 'serialnumber' 'subjectkeyid' 'needcredential' 'skipthis'
```

## Remarks

The class 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-secureblackbox_pdfverifier-class) 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-secureblackbox_pdfverifier-class) property.

The *NeedCredential* parameter specifies whether the correct credential is already available to the class 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-secureblackbox_pdfverifier-class) 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 ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

```

## Procedural Interface

```text
secureblackbox_pdfverifier_register_callback($res, 8, array($this, 'fireNotification'));
```

## Parameter List

```text
 'eventid' 'eventparam'
```

## Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. 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 class, the exact action it is performing, or the document being processed, one or both may be omitted.

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

|  |  |
| --- | --- |
| DocumentLoaded | Notifies the application that the document has been loaded. This is a backward-compatibility-only notification. Use OnDocumentLoaded event instead. |
| SignaturesLoaded | Notifies the application that the component has finished loading signatures. |
| 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 class 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 was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to TimestampServer), 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. |

# SignatureFound Event ([SecureBlackbox_PDFVerifier](#pdfverifier-class) Class)

Signifies the start of signature validation.

## Object Oriented Interface

```text
public function fireSignatureFound($param);
```

## Procedural Interface

```text
secureblackbox_pdfverifier_register_callback($res, 9, array($this, 'fireSignatureFound'));

# Config Settings ([PDFVerifier](#pdfverifier-class) Class)

 The class 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 class, access to these *internal properties* is provided through the [Config](#config-method-secureblackbox_pdfverifier-class) method.

### PDFVerifier Config Settings

**AlternateName**: TBD.TBD

**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. This value helps ASiCSigner identify the correct signature in the returned batch of responses. If using batched requests, make sure to set this property to the same value on both pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

**BuildApplicationName**: Specifies the application name used to create the signature.Use this property to set the application name used to create the signature.

For advanced settings of the build properties, use the [BuildProperties](#BuildProperties) configuration setting.

**BuildApplicationVersion**: Specifies the application version used to create the signature.Use this property to set the application version used to create the signature.

For advanced settings of the build properties, use the [BuildProperties](#BuildProperties) configuration setting.

**BuildProperties**: Specifies the build properties of the signature.Use this property to set the build properties of the signature in JSON format. Names of JSON fields correspond to the entry names in Adobe's Digital Signature Build Dictionary Specification.

Sample value:

```text
{
   "App":{
      "Name":"TestApp",
      "REx":"8.0.0"
   }
}
```

The above value sets the application name and version used to create the signature. The same result could be achieved using the [BuildApplicationName](#BuildApplicationName) and [BuildApplicationVersion](#BuildApplicationVersion) configuration settings.

Sample value 2:

```text
{
   "App":{
      "Name":"TestApp",
      "REx":"8.0.0",
      "R":524288,
      "Date":"2023-01-01 00:01",
      "OS":[
         "Win"
      ],
      "TrustedMode":true
   },
   "Filter":{
      "Name":"TestFilter",
      "R":131101,
      "Date":"2023-01-01 00:02",
      "PreRelease":true
   },
   "PubSec":{
      "R":13102,
      "Date":"2023-01-01 00:03",
      "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 1 day (86400 seconds). A value of 0 disables the absolute CRL age check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

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

The default value is 50 percent. Values are interpreted in the 0..100 range. A value of 0 disables the CRL ratio check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedCRLOverlapTime**: Specifies the time period before a cached CRL'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 CRL should be 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.

**ChainCurrentCACert**: Returns the current CA certificate.This property returns the CA certificate that is used on the current step.

**ChainCurrentCert**: Returns the certificate that is currently being validated.Use this property to obtain the body of the certificate that is currently being validated.

**ChainCurrentCRL**: Returns the current CRL.Returns the CRL object that is currently being processed.

**ChainCurrentCRLSize**: Returns the size of the current CRL.This property returns the size of the CRL object that is currently being processed.

**ChainCurrentOCSP**: Returns the current OCSP response.Returns the OCSP object that is currently being processed.

**ChainCurrentOCSPSigner**: Returns the signer of the current OCSP object.Returns the signer/CA that has issued the OCSP response that is currently being processed.

**ChainInterimDetails**: Returns the current interim validation details.This property returns the interim chain validation details.

**ChainInterimResult**: Returns the current interim validation result.Use this setting to obtain the current (mid-chain) validation result. This property applies to the current validation step and may change as the chain walk proceeds. The final result will be published in the ChainValidationResult property once the validation process completes.

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

**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.

TBD

**CustomSignedAttributes**: TBD.TBD

**CustomTrustedLists**: Specifies the custom TrustedLists.Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

**CustomTSLs**: Specifies the custom TrustedLists.Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

**CustomUnsignedAttributes**: TBD.TBD

**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 class 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 class 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.

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

**DTSSerialNumber**: Indicates the serial number of the document timestamp.Use this property to get the serial number of the document timestamp.

The value is set for document timestamp signatures.

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

**DTSTime**: Indicates the time of the document timestamp.Use this property to get the time included in the document timestamp.

The value is set for document timestamp signatures.

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

**DTSTSAName**: Indicates the TSA name of the document timestamp.Use this property to get the name of the timestamping authority that issued the document timestamp.

The value is set for document timestamp signatures when the timestamp includes a TSA name.

**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.

**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.

**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 class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class 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

**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.

**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).

**MappingName**: TBD.TBD

|  | "RIPEMD160" | The class uses RIPEMD160 hash algorithm. |
|  | "SHA3_256" | The class uses SHA3-256 hash algorithm. |
|  | "SHA3_384" | The class uses SHA3-384 hash algorithm. |
|  | "SHA3_512" | The class uses SHA3-512 hash algorithm. |
|  | "SHAKE_256" | The class uses SHAKE-256 hash algorithm. |

**PSSUsed**: Whether to use RSASSA-PSS algorithm.Although the RSASSA-PSS algorithm provides better security than a classic RSA scheme (PKCS#1-1.5), please take into account that RSASSA-PSS is a relatively new algorithm which may not be understood by older implementations. This is an alias for *UsePSS*.

**RC4KeyBits**: Specifies the number of key bits used for the RC4 algorithm.Specifies the number of key bits used for the RC4 encryption algorithm.

|  | "hybrid" | The class reassembles PDF documents in the same cases as in "auto" mode and additionally reassembles hybrid PDF documents - documents that contain cross-reference tables and cross-reference streams. |

**RevocationCacheAgePolicy**: Specifies a preset policy for cached CRL and OCSP response freshness settings.Use this setting to configure all cached revocation freshness settings at once. The default value is Default.

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. The individual settings remain available for advanced configuration and can be used after this setting to override specific values.

**LogLevel**: Specifies the debug log level.Use this property to provide the desired debug log level.

Supported values are:

|  |  |  |
| --- | --- | --- |
| none |  | None (by default) |
| fatal |  | Severe errors that cause premature termination. |
| error |  | Other runtime errors or unexpected conditions. |
| warning |  | Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". |
| info |  | Interesting runtime events (startup/shutdown). |
| debug |  | Detailed information on flow of through the system. |
| trace |  | More detailed information. |

**LogMaxEventCount**: Specifies the maximum number of events to cache before further action is taken.Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

**LogRotationMode**: Specifies the log rotation mode.Use this property to set the log rotation mode. The following values are defined:

|  |  |  |
| --- | --- | --- |
| none |  | No rotation |
| deleteolder |  | Delete older entries from the cache upon reaching LogMaxEventCount |
| keepolder |  | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) |

**MaxASN1BufferLength**: Specifies the maximal allowed length for ASN.1 primitive tag data.This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

**MaxASN1TreeDepth**: Specifies the maximal depth for processed ASN.1 trees.This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

**OCSPHashAlgorithm**: Specifies the hash algorithm to be used to identify certificates in OCSP requests.This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

**OldClientSideRSAFallback**: Specifies whether the SSH client should use a SHA1 fallback.Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

**PKICache**: Specifies which PKI elements (certificates, CRLs, OCSP responses) should be cached.The PKICache setting specifies which Public Key Infrastructure (PKI) elements should be cached to optimize performance and reduce retrieval times. It supports comma-separated values to indicate the specific types of PKI data that should be cached.

Supported Values:

|  |  |
| --- | --- |
| certificate | Enables caching of certificates. |
| crl | Enables caching of Certificate Revocation Lists (CRLs). |
| ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |

Example (default value):

```text
PKICache=certificate,crl,ocsp
```

 In this example, the component caches certificates, CRLs, and OCSP responses.

**PKICachePath**: Specifies the file system path where cached PKI data is stored.The PKICachePath setting defines the file system path where cached PKI data (e.g., certificates, CRLs, OCSP responses and Trusted Lists) will be stored. This allows the system to persistently save and retrieve PKI cache data, even across application restarts.

The default value is an empty string - no cached PKI data is stored on disk.

Example:

```text
PKICachePath=C:\Temp\cache
```

 In this example, the cached PKI data is stored in the C:\Temp\cache directory.

**ProductVersion**: Returns the version of the SecureBlackbox library.This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

**ServerSSLDHKeyLength**: Sets the size of the TLS DHE key exchange group.Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

**StaticDNS**: Specifies whether static DNS rules should be used.Set this property to enable or disable static DNS rules for the class. Works only if *UseOwnDNSResolver* is set to *true*.

Supported values are:

|  |  |  |
| --- | --- | --- |
| none |  | No static DNS rules (default) |
| local |  | Local static DNS rules |
| global |  | Global static DNS rules |

**StaticIPAddress[domain]**: Gets or sets an IP address for the specified domain name.Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the *StaticDNS* value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are divided by the | (pipe) character.

**StaticIPAddresses**: Gets or sets all the static DNS rules.Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If *StaticDNS* of the class is set to "*local*", the property returns/restores the rules from/to the internal storage of the class. If *StaticDNS* of the class is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**TLSSessionPurgeInterval**: Specifies how often the session cache should remove the expired TLS sessions.Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

**UseCRLObjectCaching**: Specifies whether reuse of loaded CRL objects is enabled.This setting enables or disables the caching of CRL objects. 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.
