The PDFSigner component signs PDF documents digitally.

Syntax

TsbxPDFSigner

Remarks

PDFSigner can sign PDF documents in accordance with a selection of PDF and PAdES signature standards. 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 property.
• When creating LTV signatures, tune up validation parameters via the RevocationCheck, OfflineMode, and IgnoreChainValidationErrors properties.
• To create a document timestamp, sign your document first, and then sign the result again with set to pslDocumentTimestamp and TimestampServer 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 and 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 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 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 property), as a stream (assign to the InputStream property), or as a byte array (assign to InputBytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via OutputFile and OutputStream respectively, or by reading the resulting document bytes from the OutputBytes property after the signing.

Having set up the input and output, call the component's Sign 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 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 and DecryptionCertificate properties, the component will fire the Encrypted event to tell your code that it needs decryption information to be able to continue with the signing. It may fire TLSCertValidate 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 instead of Sign. When the hash is ready, it will be passed back to your code with the ExternalSign 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 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 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 method. SignAsyncEnd 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 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 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 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, 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 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.

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

Data Type

Boolean

CertCAKeyID Property (PDFSigner Component)

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

Syntax

__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 generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the CertSubjectKeyID 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 property.

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

Data Type

Byte Array

  ctX509Certificate=1,
  ctX509CertificateRequest=2
};

Default Value

ctUnknown

Remarks

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

A 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 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 property.

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

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

Data Type

String

CertFriendlyName Property (PDFSigner Component)

Syntax

__property String CertFriendlyName[int CertIndex] = { read=FCertFriendlyName };

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 property.

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

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

Data Type

String

CertKeyBits Property (PDFSigner Component)

Returns the length of the public key in bits.

Syntax

__property int CertKeyBits[int CertIndex] = { read=FCertKeyBits };

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 or CertPrivateKeyBytes 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 property.

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

__property String CertKeyFingerprint[int CertIndex] = { read=FCertKeyFingerprint };

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 property. The key fingeprint 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 property.

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

Data Type

  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.

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.

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 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.

  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.

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.

Data Type

Integer

WidgetBackgroundMask Property (PDFSigner Component)

Contains the background image mask.

Syntax

__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.

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."

Sample code to add a JPEG image of size 100px x 100px and place it in position (10, 10) with an image size (30, 30): Signer.DoAction("AddImage", "ImageData=" + Utils.HexEncode(BinaryImageData) + "; ImageWidth=100; ImageHeight=100; ImageType=jpeg; X=10; Y=10; Width=30; Height=30");

Use "GetTextWidth" action to calculate the width of the given text for a specific font. The following parameters are supported:

Sample code: Signer.DoAction("GetTextWidth", "Text=Lorem Ipsum; FontSize=10; FontName=Arial Bold Italic");

Use "GetSystemFontNames" action to get a CRLF-separated list of system TrueType font names that the component supports.

Use "IsAllGlyphsAvailable" action to check if all glyphs that correspond to the given text are available for a specific font. The following parameters are required:

For standard Type 1 fonts this action always returns a "true" value.

ExtractAsyncData Method (PDFSigner Component)

Extracts user data from the DC signing service response.

Syntax

String __fastcall ExtractAsyncData(String AsyncReply);

Remarks

Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.

The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to the completion async stage.

GetAttachedBytes Method (PDFSigner Component)

Saves a PDF attachment to a byte array.

Syntax

DynamicArray<Byte> __fastcall GetAttachedBytes(int Index);

Remarks

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

GetAttachedFile Method (PDFSigner Component)

Saves a PDF attachment to a file.

Syntax

void __fastcall GetAttachedFile(int Index, String Path);

Remarks

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

Open Method (PDFSigner Component)

Opens a document for signing or updating.

Syntax

void __fastcall Open();

Remarks

Use this method to open a document for signing or updating. When finished, call Close to complete or discard the operation.

Reset Method (PDFSigner Component)

Resets the component settings.

Syntax

void __fastcall Reset();

Remarks

Reset is a generic method available in every component.

Revalidate Method (PDFSigner Component)

Revalidates a signature in accordance with current settings.

Syntax

void __fastcall Revalidate(String SigLabel);

Remarks

Use this method to re-validate a signature in the opened PDF document.

SelectInfo Method (PDFSigner Component)

Select signature information for a specific entity.

Syntax

void __fastcall SelectInfo(String EntityLabel, int InfoType, bool 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:

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.

Sign Method (PDFSigner Component)

Signs a PDF document.

Syntax

void __fastcall Sign();

Remarks

Call this method to sign the document referenced by the InputFile (or InputStream) property. The document will be signed with SigningCertificate as configured in NewSignature, and saved in OutputFile (OutputStream).

Use TrustedCertificates, KnownCertificates, RevocationCheck, OfflineMode 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 Component)

Initiates the asynchronous signing operation.

Syntax

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 (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 (or InputStream), and call SignAsyncEnd 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 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 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 Component)

Completes the asynchronous signing operation.

Syntax

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 call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (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) 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 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 Component)

Signs the document using an external signing facility.

Syntax

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 event which allows the hash value to be passed for signing.

Update Method (PDFSigner Component)

Updates a signature.

Syntax

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 to have the component obtain and embed a document timestamp for you.

Before calling this method, provide the signed document via the InputFile (or InputStream) property. The updated document will be saved to OutputFile (or OutputStream).

ChainElementDownload Event (PDFSigner Component)

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

Syntax

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.

ChainElementNeeded Event (PDFSigner Component)

Fires when an element required to validate the chain was not located.

Syntax

typedef struct {
  int Kind;
  String CertRDN;
  String CACertRDN;
} TsbxPDFSignerChainElementNeededEventParams;
typedef void __fastcall (__closure *TsbxPDFSignerChainElementNeededEvent)(System::TObject* Sender, TsbxPDFSignerChainElementNeededEventParams *e);
__property TsbxPDFSignerChainElementNeededEvent OnChainElementNeeded = { read=FOnChainElementNeeded, write=FOnChainElementNeeded };

Remarks

Subscribe to this event to be notified about missing validation elements. Use the KnownCRLs, KnownCertificates, and KnownOCSPs properties in the event handler to provide the missing piece.

ChainValidated Event (PDFSigner Component)

Reports the completion of a certificate chain validation.

Syntax

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

This event is fired when a certificate chain validation routine completes. SubjectRDN identifies the owner of the validated certificate.

ValidationResult set to 0 (zero) indicates successful chain validation.

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

ChainValidationProgress Event (PDFSigner Component)

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

Syntax

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.

DocumentLoaded Event (PDFSigner Component)

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

Syntax

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 Component)

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

Syntax

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 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 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 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 Component)

Information about errors during signing/validation.

Syntax

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 Component)

Handles remote or external decryption.

Syntax

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 Component)

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

Syntax

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: 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 Component)

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

Syntax

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:

PreRenderWidget Event (PDFSigner Component)

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

Syntax

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 Component)

Signifies the start of signature validation.

Syntax

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 Component)

Marks the completion of the signature validation routine.

Syntax

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.

TimestampFound Event (PDFSigner Component)

Signifies the start of a timestamp validation routine.

Syntax

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 Component)

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

Syntax

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 property. Set the SuppressDefault parameter to false 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 Component)

Reports the completion of the timestamp validation routine.

Syntax

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.

TLSCertNeeded Event (PDFSigner Component)

Fires when a remote TLS party requests a client certificate.

Syntax

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 event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (PDFSigner Component)

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

Syntax

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 Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

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 Component)

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

Syntax

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 event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSShutdown Event (PDFSigner Component)

Reports the graceful closure of a TLS connection.

Syntax

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 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 method.

PDFSigner Config Settings

Base Config Settings

Trappable Errors (PDFSigner Component)

PDFSigner Errors
