Syntax

PDFSigner

Remarks

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

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 classes 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 class 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 class'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 class 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 class 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 class 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 classes 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 class 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 class - 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 classes 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 class from looking for any validation tokens online. If this property is switched on, the class will only use the KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
  • IgnoreChainValidationErrors makes the class 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.

int SetKnownCertCount(int iKnownCertCount); QByteArray GetKnownCertBytes(int iKnownCertIndex); qint64 GetKnownCertHandle(int iKnownCertIndex);
int SetKnownCertHandle(int iKnownCertIndex, qint64 lKnownCertHandle);

Remarks

Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually.

The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

This property is not available at design time.

Data Type

SecureBlackboxCertificate

KnownCRLs Property (PDFSigner Class)

Default Value

""

Remarks

Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.

Supported profiles:

"BR.AD_RB_v1_0"Brazilian signature with Basic Reference (AD-RB) version 1.0
"BR.AD_RB_v1_1"Brazilian signature with Basic Reference (AD-RB) version 1.1
"BR.AD_RT_v1_0"Brazilian signature with Time Reference (AD-RT) version 1.0
"BR.AD_RT_v1_1"Brazilian signature with Time Reference (AD-RT) version 1.1
"BR.AD_RC_v1_1"Brazilian signature with Complete References (AD-RC) version 1.1
"BR.AD_RC_v1_2"Brazilian signature with Complete References (AD-RC) version 1.2
"BR.AD_RA_v1_1"Brazilian signature with References for Archiving (AD-RA) version 1.1
"BR.AD_RA_v1_2"Brazilian signature with References for Archiving (AD-RA) version 1.2
"PAdES.BASELINE-B"PAdES B-B level (ETSI TS 103 172 v2.1.1 Baseline Profile)
"PAdES.BASELINE-T"PAdES B-T level
"PAdES.BASELINE-LT.Update"PAdES B-LT level
"PAdES.BASELINE-LTA.Update"PAdES B-LTA level

The "PAdES.BASELINE-B" profile is equivalent to the following settings: Signer.NewSignature.Level = PDFSignatureLevels.pslBES; Signer.Config("AutoCollectRevocationInfo=false"); This code uses the PAdES-BES form (a signature that does not incorporate the signature-policy-identifier). Alternatively, you can use the PAdES-EPES form (a signature that does incorporate the signature-policy-identifier) with the following code modification: Signer.NewSignature.Level = PDFSignatureLevels.pslEPES;

The "PAdES.BASELINE-T" profile extends the "PAdES.BASELINE-B" profile with the following settings: Signer.TimestampServer = "https://freetsa.org/tsr";

The "PAdES.BASELINE-LT.Update" profile is applied in the Update method. It extends the signature created using the PAdES B-T level ("PAdES.BASELINE-T" profile). Signer.Config("AutoCollectRevocationInfo=true");

The "PAdES.BASELINE-LTA.Update" profile is applied in the Update method. It extends the signature created using the PAdES B-T level ("PAdES.BASELINE-T" profile). Signer.Config("AutoCollectRevocationInfo=true"); Signer.TimestampServer = "https://freetsa.org/tsr";

int secureblackbox_pdfsigner_setrevocationcheck(void* lpObj, int iRevocationCheck);
int GetRevocationCheck();
int SetRevocationCheck(int iRevocationCheck);

Default Value

1

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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. 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.

TrustedCertificates Property (PDFSigner Class)

A list of trusted certificates for chain validation.

Syntax

SecureBlackboxList<SecureBlackboxCertificate>* GetTrustedCertificates();
int SetTrustedCertificates(SecureBlackboxList<SecureBlackboxCertificate>* val);
int secureblackbox_pdfsigner_gettrustedcertcount(void* lpObj);

int SetTrustedCertCount(int iTrustedCertCount); QByteArray GetTrustedCertBytes(int iTrustedCertIndex); qint64 GetTrustedCertHandle(int iTrustedCertIndex);
int SetTrustedCertHandle(int iTrustedCertIndex, qint64 lTrustedCertHandle);

Remarks

Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.

Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

This property is not available at design time.

Data Type

SecureBlackboxCertificate

ValidationMoment Property (PDFSigner Class)

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

Syntax

ANSI (Cross Platform)

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.

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* secureblackbox_pdfsigner_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings 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, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DoAction Method (PDFSigner Class)

Performs an additional action.

Syntax

ANSI (Cross Platform)
char* DoAction(const char* lpszActionID, const char* lpszActionParams);

Unicode (Windows)
LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams);
char* secureblackbox_pdfsigner_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);
QString DoAction(const QString& qsActionID, const QString& qsActionParams);

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;....

Supported ActionIDs:

"AddImage"Adds an image to the foreground layer.
"GetTextWidth"Calculates the width of the given text for a specific font.
"GetSystemFontNames"Gets the list of system font names.
"IsAllGlyphsAvailable"Checks if all glyphs from the given text are available for a specific font.

Use "AddImage" action to add an image to the foreground layer. The following parameters are supported:

"ImageData"The image data in hex or base64 encoding. To use base64 encoding prepend an encoded data with "base64:" prefix.
"ImageWidth"The width of the image in pixels.
"ImageHeight"The height of the image in pixels.
"ImageType"The type of the image contained in ImageData parameter. Supported values: "jpeg", "jpeg2000", "custom".
"ImageBitsPerComponent"The number of bits per color space component for the image.
"ImageColorSpace"The image color space. Supported values: "RGB", "CMYK" and "Gray".
"ImageInterpolate"Specifies whether an image interpolation shall be performed by a conforming reader.
"X"The image offset from the left-hand signature widget border.
"Y"The image offset from the bottom signature widget border.
"Width"The width of the image in points.
"Height"The height of the image in points.

Parameters ImageData, ImageWidth, ImageHeight, ImageType, X, Y, Width and Height are required.

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:

"Text"Represent the text string for which you want to determine the width.
"FontName"The font name or TrueType filename. It supports the same values as Widget.FontName property.
"FontSize"The horizontal font size of the text. If omitted, the width of the text returned in units, and the width for a specific font size could be calculated by the formula: (Width / 1000) * FontSize

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:

"Text"Represent the text string that you want to check.
"FontName"The font name or TrueType filename. It supports the same values as Widget.FontName property.

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

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SignAsyncBegin Method (PDFSigner Class)

Initiates the asynchronous signing operation.

Syntax

ANSI (Cross Platform)
char* SignAsyncBegin();

Unicode (Windows)
LPWSTR SignAsyncBegin();
char* secureblackbox_pdfsigner_signasyncbegin(void* lpObj);
QString 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 class), 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

SignAsyncEnd Method (PDFSigner Class)

Completes the asynchronous signing operation.

Syntax

ANSI (Cross Platform)
int SignAsyncEnd(const char* lpszAsyncReply);

Unicode (Windows)
INT SignAsyncEnd(LPCWSTR lpszAsyncReply);
int secureblackbox_pdfsigner_signasyncend(void* lpObj, const char* lpszAsyncReply);
int SignAsyncEnd(const QString& qsAsyncReply);

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 class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SignExternal Method (PDFSigner Class)

Signs the document using an external signing facility.

Syntax

ANSI (Cross Platform)
int SignExternal();

Unicode (Windows)
INT SignExternal();
int secureblackbox_pdfsigner_signexternal(void* lpObj);
int 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 class fires the ExternalSign event which allows the hash value to be passed for signing.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Update Method (PDFSigner Class)

Updates a signature.

Syntax

ANSI (Cross Platform)
int Update(const char* lpszSigLabel);

Unicode (Windows)
INT Update(LPCWSTR lpszSigLabel);
int secureblackbox_pdfsigner_update(void* lpObj, const char* lpszSigLabel);
int Update(const QString& qsSigLabel);

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 class 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).

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

};
// To handle, connect one or more slots to this signal. void DocumentLoaded(PDFSignerDocumentLoadedEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireDocumentLoaded(PDFSignerDocumentLoadedEventParams *e) {...}

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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireEncrypted(PDFSignerEncryptedEventParams *e);
typedef struct {
int CertUsed;
const char *IssuerRDN;
const char *SerialNumber; int lenSerialNumber;
const char *SubjectKeyID; int lenSubjectKeyID;
int NeedCredential;
int SkipThis; int reserved; } PDFSignerEncryptedEventParams;
Unicode (Windows) virtual INT FireEncrypted(PDFSignerEncryptedEventParams *e);
typedef struct {
BOOL CertUsed;
LPCWSTR IssuerRDN;
LPCSTR SerialNumber; INT lenSerialNumber;
LPCSTR SubjectKeyID; INT lenSubjectKeyID;
BOOL NeedCredential;
BOOL SkipThis; INT reserved; } PDFSignerEncryptedEventParams;
#define EID_PDFSIGNER_ENCRYPTED 6

virtual INT SECUREBLACKBOX_CALL FireEncrypted(BOOL &bCertUsed, LPSTR &lpszIssuerRDN, LPSTR &lpSerialNumber, INT &lenSerialNumber, LPSTR &lpSubjectKeyID, INT &lenSubjectKeyID, BOOL &bNeedCredential, BOOL &bSkipThis);
class PDFSignerEncryptedEventParams {
public:
  bool CertUsed();

  const QString &IssuerRDN();

  const QByteArray &SerialNumber();

  const QByteArray &SubjectKeyID();

  bool NeedCredential();

  bool SkipThis();
  void SetSkipThis(bool bSkipThis);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Encrypted(PDFSignerEncryptedEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireEncrypted(PDFSignerEncryptedEventParams *e) {...}

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 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 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 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.

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 class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.

The class 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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireExternalSign(PDFSignerExternalSignEventParams *e);
typedef struct {
const char *OperationId;
const char *HashAlgorithm;
const char *Pars;
const char *Data;
char *SignedData; int reserved; } PDFSignerExternalSignEventParams;
Unicode (Windows) virtual INT FireExternalSign(PDFSignerExternalSignEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR HashAlgorithm;
LPCWSTR Pars;
LPCWSTR Data;
LPWSTR SignedData; INT reserved; } PDFSignerExternalSignEventParams;
#define EID_PDFSIGNER_EXTERNALSIGN 9

virtual INT SECUREBLACKBOX_CALL FireExternalSign(LPSTR &lpszOperationId, LPSTR &lpszHashAlgorithm, LPSTR &lpszPars, LPSTR &lpszData, LPSTR &lpszSignedData);
class PDFSignerExternalSignEventParams {
public:
  const QString &OperationId();

  const QString &HashAlgorithm();

  const QString &Pars();

  const QString &Data();

  const QString &SignedData();
  void SetSignedData(const QString &qsSignedData);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ExternalSign(PDFSignerExternalSignEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireExternalSign(PDFSignerExternalSignEventParams *e) {...}

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 class via the SignedData parameter.

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

The class 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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireNotification(PDFSignerNotificationEventParams *e);
typedef struct {
const char *EventID;
const char *EventParam; int reserved; } PDFSignerNotificationEventParams;
Unicode (Windows) virtual INT FireNotification(PDFSignerNotificationEventParams *e);
typedef struct {
LPCWSTR EventID;
LPCWSTR EventParam; INT reserved; } PDFSignerNotificationEventParams;
#define EID_PDFSIGNER_NOTIFICATION 10

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);
class PDFSignerNotificationEventParams {
public:
  const QString &EventID();

  const QString &EventParam();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Notification(PDFSignerNotificationEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireNotification(PDFSignerNotificationEventParams *e) {...}

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:

DocumentLoadedReports the completion of PDF document processing by the component. Use the event handler to access document-related information, such as page number and document file details. The EventParam value passed with this EventID is empty.
BeforeTimestampThis event is fired before a timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings.
TimestampErrorThis event is only fired if the class failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info.
TimestampRequestA 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.

SignatureWidgetPrepareAnother copy of the signature widget needs to be configured. Use the event handler to configure individual widgets when creating multi-widget signatures. The Notification event with this event ID will be fired repeatedly until the LastSignatureWidget configuration setting is set to true.

The EventParam value passed with this EventID is empty.

PreRenderWidget Event (PDFSigner Class)

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

Syntax

ANSI (Cross Platform)
virtual int FirePreRenderWidget(PDFSignerPreRenderWidgetEventParams *e);
typedef struct {
int AddAnother;
int ResetAnother; int reserved; } PDFSignerPreRenderWidgetEventParams;
Unicode (Windows) virtual INT FirePreRenderWidget(PDFSignerPreRenderWidgetEventParams *e);
typedef struct {
BOOL AddAnother;
BOOL ResetAnother; INT reserved; } PDFSignerPreRenderWidgetEventParams;
#define EID_PDFSIGNER_PRERENDERWIDGET 11

virtual INT SECUREBLACKBOX_CALL FirePreRenderWidget(BOOL &bAddAnother, BOOL &bResetAnother);
class PDFSignerPreRenderWidgetEventParams {
public:
  bool AddAnother();
  void SetAddAnother(bool bAddAnother);

  bool ResetAnother();
  void SetResetAnother(bool bResetAnother);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void PreRenderWidget(PDFSignerPreRenderWidgetEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FirePreRenderWidget(PDFSignerPreRenderWidgetEventParams *e) {...}

Remarks

The class 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 Class)

Signifies the start of signature validation.

Syntax

ANSI (Cross Platform)
virtual int FireSignatureFound(PDFSignerSignatureFoundEventParams *e);
typedef struct {
int Index;
const char *EntityLabel;
const char *IssuerRDN;
const char *SerialNumber; int lenSerialNumber;

  const QString &EntityLabel();

  const QString &IssuerRDN();

  const QByteArray &SerialNumber();

  const QByteArray &SubjectKeyID();

  bool CertFound();

  bool ValidateSignature();
  void SetValidateSignature(bool bValidateSignature);

  bool ValidateChain();
  void SetValidateChain(bool bValidateChain);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SignatureFound(PDFSignerSignatureFoundEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireSignatureFound(PDFSignerSignatureFoundEventParams *e) {...}

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 class 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 Class)

Marks the completion of the signature validation routine.

Syntax

};
// To handle, connect one or more slots to this signal. void SignatureValidated(PDFSignerSignatureValidatedEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireSignatureValidated(PDFSignerSignatureValidatedEventParams *e) {...}

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.

svtValid0The signature is valid

svtUnknown1Signature validity is unknown

svtCorrupted2The signature is corrupted

svtSignerNotFound3Failed to acquire the signing certificate. The signature cannot be validated.

  const QByteArray &SubjectKeyID();

  bool CertFound();

  bool ValidateTimestamp();
  void SetValidateTimestamp(bool bValidateTimestamp);

  bool ValidateChain();
  void SetValidateChain(bool bValidateChain);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TimestampFound(PDFSignerTimestampFoundEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTimestampFound(PDFSignerTimestampFoundEventParams *e) {...}

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 class 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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireTimestampRequest(PDFSignerTimestampRequestEventParams *e);
typedef struct {
const char *TSA;
const char *TimestampRequest;
char *TimestampResponse;
int SuppressDefault; int reserved; } PDFSignerTimestampRequestEventParams;
Unicode (Windows) virtual INT FireTimestampRequest(PDFSignerTimestampRequestEventParams *e);
typedef struct {
LPCWSTR TSA;
LPCWSTR TimestampRequest;
LPWSTR TimestampResponse;
BOOL SuppressDefault; INT reserved; } PDFSignerTimestampRequestEventParams;
#define EID_PDFSIGNER_TIMESTAMPREQUEST 15

virtual INT SECUREBLACKBOX_CALL FireTimestampRequest(LPSTR &lpszTSA, LPSTR &lpszTimestampRequest, LPSTR &lpszTimestampResponse, BOOL &bSuppressDefault);
class PDFSignerTimestampRequestEventParams {
public:
  const QString &TSA();

  const QString &TimestampRequest();

  const QString &TimestampResponse();
  void SetTimestampResponse(const QString &qsTimestampResponse);

  bool SuppressDefault();
  void SetSuppressDefault(bool bSuppressDefault);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TimestampRequest(PDFSignerTimestampRequestEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTimestampRequest(PDFSignerTimestampRequestEventParams *e) {...}

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 Class)

Reports the completion of the timestamp validation routine.

Syntax

ANSI (Cross Platform)
virtual int FireTimestampValidated(PDFSignerTimestampValidatedEventParams *e);
typedef struct {

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.

svtValid0The signature is valid

svtUnknown1Signature validity is unknown

svtCorrupted2The signature is corrupted

svtSignerNotFound3Failed to acquire the signing certificate. The signature cannot be validated.

TLSCertNeeded Event (PDFSigner Class)

Fires when a remote TLS party requests a client certificate.

Syntax

ANSI (Cross Platform)
virtual int FireTLSCertNeeded(PDFSignerTLSCertNeededEventParams *e);
typedef struct {
const char *Host;
const char *CANames; int reserved; } PDFSignerTLSCertNeededEventParams;
Unicode (Windows) virtual INT FireTLSCertNeeded(PDFSignerTLSCertNeededEventParams *e);
typedef struct {
LPCWSTR Host;
LPCWSTR CANames; INT reserved; } PDFSignerTLSCertNeededEventParams;
#define EID_PDFSIGNER_TLSCERTNEEDED 17

virtual INT SECUREBLACKBOX_CALL FireTLSCertNeeded(LPSTR &lpszHost, LPSTR &lpszCANames);
class PDFSignerTLSCertNeededEventParams {
public:
  const QString &Host();

  const QString &CANames();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TLSCertNeeded(PDFSignerTLSCertNeededEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTLSCertNeeded(PDFSignerTLSCertNeededEventParams *e) {...}

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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireTLSCertValidate(PDFSignerTLSCertValidateEventParams *e);
typedef struct {
const char *ServerHost;
const char *ServerIP;
int Accept; int reserved; } PDFSignerTLSCertValidateEventParams;
Unicode (Windows) virtual INT FireTLSCertValidate(PDFSignerTLSCertValidateEventParams *e);
typedef struct {
LPCWSTR ServerHost;
LPCWSTR ServerIP;
BOOL Accept; INT reserved; } PDFSignerTLSCertValidateEventParams;
#define EID_PDFSIGNER_TLSCERTVALIDATE 18

virtual INT SECUREBLACKBOX_CALL FireTLSCertValidate(LPSTR &lpszServerHost, LPSTR &lpszServerIP, BOOL &bAccept);
class PDFSignerTLSCertValidateEventParams {
public:
  const QString &ServerHost();

  const QString &ServerIP();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TLSCertValidate(PDFSignerTLSCertValidateEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTLSCertValidate(PDFSignerTLSCertValidateEventParams *e) {...}

Remarks

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, classes 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 class, and can be adjusted if needed.

TLSEstablished Event (PDFSigner Class)

Fires when a TLS handshake with Host successfully completes.

Syntax

ANSI (Cross Platform)
virtual int FireTLSEstablished(PDFSignerTLSEstablishedEventParams *e);
typedef struct {
const char *Host;
const char *Version;
const char *Ciphersuite;
const char *ConnectionId; int lenConnectionId;
int Abort; int reserved; } PDFSignerTLSEstablishedEventParams;
Unicode (Windows) virtual INT FireTLSEstablished(PDFSignerTLSEstablishedEventParams *e);
typedef struct {
LPCWSTR Host;
LPCWSTR Version;
LPCWSTR Ciphersuite;
LPCSTR ConnectionId; INT lenConnectionId;
BOOL Abort; INT reserved; } PDFSignerTLSEstablishedEventParams;
#define EID_PDFSIGNER_TLSESTABLISHED 19

virtual INT SECUREBLACKBOX_CALL FireTLSEstablished(LPSTR &lpszHost, LPSTR &lpszVersion, LPSTR &lpszCiphersuite, LPSTR &lpConnectionId, INT &lenConnectionId, BOOL &bAbort);
class PDFSignerTLSEstablishedEventParams {
public:
  const QString &Host();

  const QString &Version();

  const QString &Ciphersuite();

  const QByteArray &ConnectionId();

  bool Abort();
  void SetAbort(bool bAbort);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TLSEstablished(PDFSignerTLSEstablishedEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTLSEstablished(PDFSignerTLSEstablishedEventParams *e) {...}

Remarks

The class 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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireTLSHandshake(PDFSignerTLSHandshakeEventParams *e);
typedef struct {
const char *Host;
int Abort; int reserved; } PDFSignerTLSHandshakeEventParams;
Unicode (Windows) virtual INT FireTLSHandshake(PDFSignerTLSHandshakeEventParams *e);
typedef struct {
LPCWSTR Host;
BOOL Abort; INT reserved; } PDFSignerTLSHandshakeEventParams;
#define EID_PDFSIGNER_TLSHANDSHAKE 20

virtual INT SECUREBLACKBOX_CALL FireTLSHandshake(LPSTR &lpszHost, BOOL &bAbort);
class PDFSignerTLSHandshakeEventParams {
public:
  const QString &Host();

  bool Abort();
  void SetAbort(bool bAbort);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TLSHandshake(PDFSignerTLSHandshakeEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTLSHandshake(PDFSignerTLSHandshakeEventParams *e) {...}

Remarks

The class 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 Class)

Reports the graceful closure of a TLS connection.

Syntax

ANSI (Cross Platform)
virtual int FireTLSShutdown(PDFSignerTLSShutdownEventParams *e);
typedef struct {
const char *Host; int reserved; } PDFSignerTLSShutdownEventParams;
Unicode (Windows) virtual INT FireTLSShutdown(PDFSignerTLSShutdownEventParams *e);
typedef struct {
LPCWSTR Host; INT reserved; } PDFSignerTLSShutdownEventParams;
#define EID_PDFSIGNER_TLSSHUTDOWN 21

virtual INT SECUREBLACKBOX_CALL FireTLSShutdown(LPSTR &lpszHost);
class PDFSignerTLSShutdownEventParams {
public:
  const QString &Host();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void TLSShutdown(PDFSignerTLSShutdownEventParams *e);
// Or, subclass PDFSigner and override this emitter function. virtual int FireTLSShutdown(PDFSignerTLSShutdownEventParams *e) {...}

Remarks

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

Certificate Type

Encapsulates an individual X.509 certificate.

Syntax

SecureBlackboxCertificate (declared in secureblackbox.h)

Remarks

This type keeps and provides access to X.509 certificate details.

Fields

Bytes
char* (read-only)

Default Value:

Returns the raw certificate data in DER format.

CA
int

Default Value: FALSE

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

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

CAKeyID
char* (read-only)

Default Value:

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 setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

CertType
int (read-only)

Default Value: 0

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 class to load or create new certificate and certificate requests objects.

CRLDistributionPoints
char*

Default Value: ""

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

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

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

Curve
char*

Default Value: ""

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

Fingerprint
char* (read-only)

Default Value: ""

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.

FriendlyName
char* (read-only)

Default Value: ""

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.

Handle
int64

Default Value: 0

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

HashAlgorithm
char*

Default Value: ""

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 to find out the hash algorithm that is part of the certificate signature.

Use the , , and properties to get more details about the key the certificate contains.

KeyBits
int (read-only)

Default Value: 0

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 or property would typically contain auxiliary values, and therefore be longer.

KeyFingerprint
char* (read-only)

Default Value: ""

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 property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

KeyUsage
int

Default Value: 0

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

This value is a bit mask of the following values:

ckuUnknown0x00000Unknown key usage

ckuDigitalSignature0x00001Digital signature

ckuNonRepudiation0x00002Non-repudiation

ckuKeyEncipherment0x00004Key encipherment

ckuDataEncipherment0x00008Data encipherment

ckuKeyAgreement0x00010Key agreement

ckuKeyCertSign0x00020Certificate signing

ckuCRLSign0x00040Revocation signing

ckuEncipherOnly0x00080Encipher only

ckuDecipherOnly0x00100Decipher only

ckuServerAuthentication0x00200Server authentication

ckuClientAuthentication0x00400Client authentication

ckuCodeSigning0x00800Code signing

ckuEmailProtection0x01000Email protection

ckuTimeStamping0x02000Timestamping

ckuOCSPSigning0x04000OCSP signing

ckuSmartCardLogon0x08000Smartcard logon

ckuKeyPurposeClientAuth0x10000Kerberos - client authentication

ckuKeyPurposeKDC0x20000Kerberos - KDC

Set this property before generating the certificate to propagate the key usage flags to the new certificate.

KeyValid
int (read-only)

Default Value: FALSE

Returns True if the certificate's key is cryptographically valid, and False otherwise.

OCSPLocations
char*

Default Value: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's Generate method to propagate it to the new certificate.

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

OCSPNoCheck
int

Default Value: FALSE

Accessor to the value of the certificate's ocsp-no-check extension.

Origin
int (read-only)

Default Value: 0

Returns the location that the certificate was taken or loaded from.

PolicyIDs
char*

Default Value: ""

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

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

PrivateKeyBytes
char* (read-only)

Default Value:

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

PrivateKeyExists
int (read-only)

Default Value: FALSE

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from , and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

PrivateKeyExtractable
int (read-only)

Default Value: FALSE

Indicates whether the private key is extractable (exportable).

PublicKeyBytes
char* (read-only)

Default Value:

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

Qualified
int (read-only)

Default Value: FALSE

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

QualifiedStatements
int

Default Value: 0

Returns a simplified qualified status of the certificate.

Qualifiers
char* (read-only)

Default Value: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

SelfSigned
int (read-only)

Default Value: FALSE

Indicates whether the certificate is self-signed (root) or signed by an external CA.

SerialNumber
char*

Default Value:

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

SigAlgorithm
char* (read-only)

Default Value: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

Source
int (read-only)

Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

Subject
char* (read-only)

Default Value: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via .

SubjectAlternativeName
char*

Default Value: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

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

SubjectKeyID
char*

Default Value:

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The and properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

SubjectRDN
char*

Default Value: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

Valid
int (read-only)

Default Value: FALSE

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

ValidFrom
char*

Default Value: ""

The time point at which the certificate becomes valid, in UTC.

ValidTo
char*

Default Value: ""

The time point at which the certificate expires, in UTC.

Constructors

Certificate()

Creates a new object with default field values.

CRL Type

Represents a Certificate Revocation List.

Syntax

SecureBlackboxCRL (declared in secureblackbox.h)

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

Fields

Bytes
char* (read-only)

Default Value:

Returns the raw CRL data in DER format.

CAKeyID
char*

Default Value:

A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL.

EntryCount
int (read-only)

Default Value: 0

Returns the number of certificate status entries in the CRL.

Handle
int64

Default Value: 0

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

Issuer
char* (read-only)

Default Value: ""

The common name of the CRL issuer (CA), typically a company name.

IssuerRDN
char* (read-only)

Default Value: ""

A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer.

Location
char* (read-only)

Default Value: ""

The URL that the CRL was downloaded from.

NextUpdate
char*

Default Value: ""

The planned time and date of the next version of this CRL to be published.

SigAlgorithm
char*

Default Value: "0"

The public key algorithm that was used by the CA to sign this CRL.

Source
int (read-only)

Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

TBS
char* (read-only)

Default Value:

The to-be-signed part of the CRL (the CRL without the signature part).

ThisUpdate
char*

Default Value: ""

The date and time at which this version of the CRL was published.

Constructors

CRL()

Creates an empty CRL object.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Syntax

SecureBlackboxExternalCrypto (declared in secureblackbox.h)

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

AsyncDocumentID
char*

Default Value: ""

Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component 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 the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
char*

Default Value: ""

Custom parameters to be passed to the signing service (uninterpreted).

Data
char*

Default Value: ""

Additional data to be included in the async state and mirrored back by the requestor.

ExternalHashCalculation
int

Default Value: FALSE

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth class.

If set to true, the class will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

HashAlgorithm
char*

Default Value: "SHA256"

Specifies the request's signature hash algorithm.

KeyID
char*

Default Value: ""

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

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

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

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

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

KeySecret
char*

Default Value: ""

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

The time is provided in UTC.

CompatibilityErrors
int (read-only)

Default Value: 0

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.

ContainsLongTermInfo
int (read-only)

Default Value: FALSE

TBD

CoverageEndsAt
int (read-only)

Default Value: 0

Indicates the 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 method of the PDFVerifier class to extract the exact revision that was signed.

CustomData
char*

Default Value:

Uninterpreted custom data to save with the signature.

EmptyField

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

Handle
int64

Default Value: 0

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

char*

Default Value: "0"

Use this property to manually adjust the size of the stretched background picture in the vertical direction.

BackgroundImageHeight
int

Default Value: 0

The height of the background image in pixels.

It is important that this property matches the exact size of the image when a custom background is used. The width and height of the background image have no direct relation to the dimensions of the signature widget on the document page, and are only used to indicate the parameters of the image to the PDF processor. Big images will ultimately be squeezed to fit in the widget, and smaller ones stretched.

pwitCustom2Custom background format

BackgroundImageWidth
int

Default Value: 0

The width of the background image in pixels.

It is important that this property matches the exact size of the image when a custom background is used. The width and height of the background image have no direct relation to the dimensions of the signature widget on the document page, and are only used to indicate the parameters of the image to the PDF processor. Big images will ultimately be squeezed to fit in the widget, and smaller ones stretched.

BackgroundMask
char*

Default Value:

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.

BackgroundPosition
char*

Default Value: ""

The position of the widget background.

Specifies the position of the background image.

The value may be:

The keyword value "center", which centers the image.

A pair of coordinates ("10 5.5"), in which one value defines X and the other defines Y starting from the bottom-left corner.

char*

Default Value: ""

Specifies a custom background content stream for the pwbsCustom .

CustomVisualStatusMatrix
char*

Default Value: ""

Defines the custom visual status matrix.

Use of this property makes sense only if a visual status icon is displayed over the signature (). Prior to Acrobat 6, a signature's visual appearance was modified with a status icon, e.g., "valid" or "invalid". The visual status matrix is used to position the icon in the signature widget. If CustomVisualStatusMatrix is empty, the value of '0.25 0 0 0.25 0 0' is used.

DateFormat
char*

Default Value: ""

The format string used to display the signing date and time in the signature widget.

Leave this property empty (default value) to use the default formatting.

Use the "L" value to convert UTC time to local time using the default formatting, or use the "L:" prefix with a custom date time formatting string.

FontName
char*

Default Value: ""

Specifies the font name for the signature text.

Use this property to specify a Type 1 or TrueType font name for the signature text.

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

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

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

The list of system TrueType font names that the component supports could be obtained using the DoAction method with the "GetSystemFontNames" action ID.

Use the FontPaths configuration setting (accessed via Config) to specify font search paths in case the TrueType font filename is provided.

Handle
int64

Default Value: 0

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

Header
char*

Default Value: "#auto"

Specifies the header text to put on the signature widget. Keep this property set to #auto to make the component generate the header automatically.

Tells the component to discard any existing widget parameters when signing empty signature fields.

IgnoreExistingAppearance only makes sense for signatures created by signing existing empty signature fields with pre-defined widget descriptions.

InvertMask
int

Default Value: FALSE

Specifies whether should be inverted.

Set this property to flip all the bits in the mask, by making opaque all the bits declared by the mask as transparent, and making transparent all the bits declared as opaque.

Invisible
int

Default Value: FALSE

Controls whether the signature widget is visible on the page.

ShowDate
int

Default Value: TRUE

Whether to display the signing date and time details on the widget.

int

Default Value: FALSE

Specifies whether to show the signature's status icon.

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

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

Default Value: 0

Enables or disables certificate-based client authentication.

Set this property to true to tune up the client authentication type:

ccatNoAuth0
ccatRequestCert1
ccatRequireCert2

ECCurves
char*

Default Value: ""

Defines the elliptic curves to enable.

Extensions
char*

Default Value: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
int

Default Value: FALSE

Whether to force TLS session resumption when the destination address changes.

PreSharedIdentity
char*

Default Value: ""

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

PreSharedKey
char*

Default Value: ""

Contains the pre-shared key for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

PreSharedKeyCiphersuite
char*

Default Value: ""

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

RenegotiationAttackPreventionMode
int

Default Value: 2

Selects the renegotiation attack prevention mechanism.

The following options are available:

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
int

Default Value: 1

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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. 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.

Constructors

TLSSettings()

Creates a new TLSSettings object.

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the PDFSigner class.

Methods

GetCount This method returns the current size of the collection.

int GetCount() {}

SetCount This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.

int SetCount() {}

Get This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.

T* Get(int index) {}

Set This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.

T* Set(int index, T* value) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The PDFSigner class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the PDFSigner class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

This method is called automatically when a SecureBlackboxStream object is deleted.

Flush Forces all data held by the stream's buffers to be written out to storage.

int Flush() { return 0; }

Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0.

Read Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.

int Read(void* buffer, int count) = 0;

Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream.

Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed.

Seek Sets the current position within the stream based on a particular point of origin.

int64 Seek(int64 offset, int seekOrigin) = 0;

Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:

  • 0: Seek from beginning.
  • 1: Seek from current position.
  • 2: Seek from end.

Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged.

Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported.

Write Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.

int Write(const void* buffer, int count) = 0;

Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream.

Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (PDFSigner 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 method.

PDFSigner Config Settings

AddOutputIntents:   Specifies output intents to be added to the document.

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

Sample value: { "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 and BuildApplicationVersion configuration settings.

Sample value 2: { "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 } }

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

Specifies whether revocation info for timestamps should be collected automatically.

CustomTextCount:   The number of custom text blocks on the signature widget.

Use this property to set or get the number of custom text blocks on the signature widget.

CustomTextFontResourceName[Index]:   The font resource name to use for the custom text block.

This indexed setting specifies the font resource name to use for the custom text block.

CustomTextFontSizeX[Index]:   The horizontal font size scale.

This indexed setting provides access to the horizontal compound of the custom text font size.

CustomTextFontSizeY[Index]:   The vertical font size scale.

This indexed setting provides access to the vertical compound of the custom text font size.

CustomTextText[Index]:   A text to show on a custom signature widget text block.

This indexed setting provides access to the text to be placed on a specific signature widget text block. CustomTextText[0] specifies the text on the first block, CustomTextText[1] on the second block, and so on. Use the CustomTextCount property to get or set the number of custom text blocks.

CustomTextX[Index]:   The horizontal offset of the text block.

This indexed setting provides access to the horizontal offset of the custom text block on the widget.

CustomTextY[Index]:   The vertical offset of the text block.

This indexed setting provides access to the vertical offset of the custom text block on the widget.

DateFontSize:   The font size of the date/time text on the signature widget.

Use this property to specify the font size to be used for the date/time text on the signature widget.

DeepValidation:   Whether a complete validation should be performed.

If this property is switched on, a "deep" signature validation is performed, i.e., all certificate chains are validated, and all revocation checks are performed.

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).

EmptyFullFieldName:   Specifies the full name of the empty signature field to sign.

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). The 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.

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 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.

IgnoreTimestampFailure:   Whether to ignore timestamping failures during signing.

Specifies whether to ignore timestamping failures during signing.

ImplicitlyTrustSelfSignedCertificates:   Whether to trust self-signed certificates.

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

IncludeKnownRevocationInfoToSignature:   Whether to include custom revocation info into the signature.

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

IncludeRevocationInfoToAdbeAttribute:   Whether to save revocation info in PDF-compliant form.

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

LastSignatureWidget:   Specifies that it is the last signature widget to be added.

Set this property to False to add one more signature widget along with the signature.

This setting is used by the Notification event when the EventID parameter is "SignatureWidgetPrepare" to allow support for multi-widget signatures.

If this property is set to true, provide your certificate via the TLSClientChain property. Note that the class may fire this event more than once during each operation, as more than one TLS-enabled server may need to be contacted.

TLSValidationLog:   Contains the log of the TLS server certificate validation.

Check this property in the TLSCertValidate event handler to retrieve the validation log of the TLS server.

TolerateMinorChainIssues:   Whether to tolerate minor chain issues.
