PDFSigner Class
Properties Methods Events Configuration Settings Errors
The PDFSigner class signs PDF documents digitally.
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 TimestampServer property.
- When creating LTV signatures, tune up validation parameters via 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 CertificateManager and CertificateStorage components to load the signing certificate. Assign the certificate to SigningCertificate property, and optionally provide the remainder of its chain via SigningChain property.
Note: If signing with a non-exportable key (such as residing on a hardware device or in the cloud), please make sure you keep the original CertificateStorage object open until the signing is completed. This is because the storage component provides a 'bridge' to the private key. If the storage is closed prematurely, this bridge is destroyed, and the private key can't be used.
You don't need to provide a signing certificate or chain when creating document timestamp signatures, since this type of signatures 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.
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 InputFile property), as a stream (assign to InputStream property), or as a byte array (assign to InputBytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via OutputFile and OutputStream respectively, or by reading the resulting document bytes from the OutputBytes property after the signing.
Having set up the input and output, call the component's Sign method. This will initiate the signing process. Depending on the settings, the signing may be as straightforward as calculating the document hash and signing it with the private key (e.g. in PAdES-BES signing variant), or it may involve advanced chain validation routines (PAdES-LTV). During the latter the component may contact a number of external revocation information sources (CRL and OCSP servers) to establish the validity of the signing certificate.
If a TSA server was provided via the TimestampServer property, the component will contact it too to timestamp the new signature.
During the signing PDFSigner may fire events to let your code know of certain conditions. If the input document is encrypted but no decryption parameters were found in Password and DecryptionCertificate properties, the component would fire DecryptionInfoNeeded event to tell your code that it needs decryption information to be able to continue with the signing. It may fire TLSCertValidate if one of the HTTP endpoints involved during the operation (which may be a CRL, OCSP, or TSA service) works over TLS and needs its certificate to be validated.
External signing and DCAuth
PDFSigner, like many other components offered by the product, supports two methods of signing with external keys. These methods are fully independent of each other: you can choose the one that suits your usage scenario best.
Synchronous method: ExternalSign
This is a simpler method that basically lets you infiltrate into the heart of the signing routine by taking care of the hash signing operation. The component does the rest of the job (hash calculation, preparation of signature objects, CRL/OCSP retrieval).
To initiate this method, call SignExternal instead of Sign. When the hash is ready, it will be passed back to your code with ExternalSign event. Your event handler needs to sign the hash with the private key and return the created signature back to the component - which will embed it into the document.
You don't need your signing certificate to contain an associated private key when using this method. The certificate itself (its public copy) may be needed though, as it is often included in the hash calculation.
This method is synchronous, meaning SignExternal provides you the results immediately upon its completion.
Asynchronous method: DCAuth
DCAuth is a SecureBlackbox know-how technology. This protocol was designed to allow sharing of private keys across environments, allowing the signer and the private key to reside on different systems. It works in the following way:
- The signing party - such as PDFSigner - initiates the operation using 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, 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 controls, 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. Below is given a summary of such parameters.
- RevocationCheck property 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 class from looking for any validation tokens online. If this property is switched on, the component will only use KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
- IgnoreChainValidationErrors makes the component ignore any major validation issues it encounters (such us an untrusted chain or missing CRL). This option is handy for debugging and for creating signatures in the environments where the signing certificate is not trusted.
- KnownCertificates, KnownCRLs, and KnownOCSPs let you provide your own validation material. This may be useful when working in OfflineMode, where the signer has no access to the validation sources, or where the validation material has already been collected.
- TrustedCertificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative for 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.

ExternalCryptoKeyID Property (PDFSigner Class)
The ID of the pre-shared key used for DC request authentication.
Syntax
QString GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(QString qsExternalCryptoKeyID);
Default Value
""
Remarks
The ID of the pre-shared key used for DC request authentication.
Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret 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";
Data Type
String
ExternalCryptoKeySecret Property (PDFSigner Class)
The pre-shared key used for DC request authentication.
Syntax

Default Value

Remarks
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
Certificate Revocation Lists (CRL) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.
| crcNone (0) | No revocation checking |
| crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
| crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
| crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
| crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
| crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
| crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL (8) | At 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

SigBackgroundMask Property (PDFSigner Class)
Contains the background image mask.
Syntax
QByteArray GetSigBackgroundMask();
int SetSigBackgroundMask(QByteArray qbaSigBackgroundMask);
Remarks
Contains the background image mask.
Masks provide 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 basing 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 the bitmap of your signature widget bitmap row to 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 '1' bit if you want it to be transparent, or '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 SetSigBackgroundMask().
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 SetSigBackgroundMask().
This property is not available at design time.

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."

CRC_ANY_CRL(5),
CRC_ANY_OCSP(6),
CRC_ANY_CRLOR_OCSP(7),
CRC_ANY_OCSPOR_CRL(8)
Default Value
1
Remarks
Specifies the kind(s) of revocation check to perform.
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
| crcNone (0) | No revocation checking |
| crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
| crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
| crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
| crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
| crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
| crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL (8) | At 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Data Type
Integer
TrustedCertBytes Property (PDFSigner Class)
Returns raw certificate data in DER format.
Syntax
QByteArray GetTrustedCertBytes(int iTrustedCertIndex);
Remarks
Returns raw certificate data in DER format.
The TrustedCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the TrustedCertCount property.
This property is read-only and not available at design time.
Data Type
Byte Array
TrustedCertHandle Property (PDFSigner Class)
Allows to get or set a 'handle', a unique identifier of the underlying property object.
Syntax
qint64 GetTrustedCertHandle(int iTrustedCertIndex);
int SetTrustedCertHandle(int iTrustedCertIndex, qint64 lTrustedCertHandle);
Default Value
0
Remarks
Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.
When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object
after such operation.
pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
The TrustedCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the TrustedCertCount property.
This property is not available at design time.
Data Type
Long64
ValidationLog Property (PDFSigner Class)
Contains the complete log of the certificate validation routine.
Syntax
QString GetValidationLog();
Default Value
""
Remarks
Use this property to access the chain validation log produced by the class. The log can be very useful when investigating issues with chain validation, as it contains a step-by-step trace of the entire validation procedure.
This property is read-only and not available at design time.
Data Type
String
Config Method (PDFSigner Class)
Sets or retrieves a configuration setting.
Syntax
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
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
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 of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....
Error Handling
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.
ExtractAsyncData Method (PDFSigner Class)
Extracts user data from the DC signing service response.
Syntax
QString ExtractAsyncData(const QString& qsAsyncReply);
Remarks
Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.
The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to completion async stage.
Error Handling
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.
Sign Method (PDFSigner Class)
Signs a PDF document.
Syntax
int Sign();
Remarks
Call this method to sign the document referenced by InputFile (or InputStream) property. The document will be signed with SigningCertificate as configured in Signature, and saved in OutputFile (OutputStream).
Use TrustedCertificates, KnownCertificates, RevocationCheck, OfflineMode and other properties of class to adjust chain validation parameters. After the signing, the chain validation log will be available in ValidationLog property.
Error Handling
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.)
SignAsyncBegin Method (PDFSigner Class)
Initiates the asynchronous signing operation.
Syntax
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.
AsyncState is a message of the distributed cryptography (DC) protocol. DC protocol is based on 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 control), which processes it and produces a matching signatures 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 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 asmdPKCS1 method and no public copy of the certificate provided (resulting in omission of the 'signingCertificate' attribute from the signature), however, most of the modern PDF processors will reject such signatures as invalid or non-compliant.
Error Handling
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
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 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.
AsyncState is a message of the distributed cryptography (DC) protocol.

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 control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.
Error Handling
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
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 ExternalSign event which allows to pass the hash value for signing.
Error Handling
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
int Update();
Remarks
PDF signature may be updated from time to time by embedding newer/missing revocation information. The update approach is typically used to extend validity of an LTV signature.
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 InputFile (or InputStream) property. The updated document will be saved to OutputFile (or OutputStream).
Error Handling
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.)

Remarks
TBD.
DecryptionInfoNeeded Event (PDFSigner Class)
Requests decryption information during decryption, signing, or validation.
Syntax
class PDFSignerDecryptionInfoNeededEventParams {
public:
bool CancelDecryption();
void SetCancelDecryption(bool bCancelDecryption);
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void DecryptionInfoNeeded(PDFSignerDecryptionInfoNeededEventParams *e);
// Or, subclass PDFSigner and override this emitter function.
virtual int FireDecryptionInfoNeeded(PDFSignerDecryptionInfoNeededEventParams *e) {...}
Remarks
This event is fired when the component needs decryption information to be provided by the user.
Use EncryptionType property to identify the document encryption type used, and then set Password or DecryptionCertificate (DecryptionCertificates) properties accordingly.
The class fires this event repeatedly until suitable decryption information is provided. To terminate the operation, set CancelDecryption to true.
Error Event (PDFSigner Class)
Information about errors during signing/validation.
Syntax
class PDFSignerErrorEventParams {
public:
int ErrorCode();
const QString &Description();
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void Error(PDFSignerErrorEventParams *e);
// Or, subclass PDFSigner and override this emitter function.
virtual int FireError(PDFSignerErrorEventParams *e) {...}
Remarks

ExternalDecrypt Event (PDFSigner Class)
Handles remote or external decryption.
Syntax
class PDFSignerExternalDecryptEventParams {
public:

const QString &Algorithm();
const QString &Pars();
const QString &EncryptedData();
const QString &Data();
void SetData(const QString &qsData);
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void ExternalDecrypt(PDFSignerExternalDecryptEventParams *e);
// Or, subclass PDFSigner and override this emitter function.
virtual int FireExternalDecrypt(PDFSignerExternalDecryptEventParams *e) {...}
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 a encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for 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.
A 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

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 component via SignedData parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for 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 a .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();
};

This event notifies the application about an underlying control flow event.
Syntax
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 component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.
The unique identifier of the event is provided in EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.
This class can fire this event with the following EventID values:
| DocumentLoaded | Reports the completion of PDF document processing by the component. Use the event handler to access document-related information, such as page number and document file details. The EventParam value passed with this EventID is empty. |
| TimestampRequest | A timestamp is requested from the custom timestamping
authority. This event is only fired if TimestampServer was set to a
virtual:// URI. The EventParam parameter contains the
TSP request (or the plain hash, depending on the value provided to
TimestampServer), in base16, that needs to be sent to the TSA.
Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property. |
| SignatureWidgetPrepare | Another copy of the signature widget needs
to be configured. Use the event handler to configure individual widgets
when creating multi-widget signatures. The Notification event with this
event ID will be fired repeatedly until the LastSignatureWidget
configuration property is set to true.
The EventParam value passed with this EventID is empty. |
RecipientFound Event (PDFSigner Class)
Provides recipient certificate details to the application.
Syntax
class PDFSignerRecipientFoundEventParams {
public:
const QString &IssuerRDN();
const QByteArray &SerialNumber();
const QByteArray &SubjectKeyID();
bool CertFound();
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void RecipientFound(PDFSignerRecipientFoundEventParams *e);
// Or, subclass PDFSigner and override this emitter function.
virtual int FireRecipientFound(PDFSignerRecipientFoundEventParams *e) {...}
Remarks
The class fires this event when processing encrypted documents to report encryption certificate details to the user.
Subscribe to this event to obtain encryption certificate information and pass the corresponding certificate to the class via DecryptionCertificate (DecryptionCertificates) property.
TLSCertValidate Event (PDFSigner Class)
This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.
Syntax
class PDFSignerTLSCertValidateEventParams {
public:
const QString &ServerHostname();
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 TLSServerChain property to access the certificate chain. In general case, components may contact a number of TLS endpoints during their work, depending on their configuration.
Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.
ValidationProgress Event (PDFSigner Class)
TBD.
Syntax
class PDFSignerValidationProgressEventParams {
public:
const QString &ValidationEventType();

// Or, subclass PDFSigner and override this emitter function.
virtual int FireValidationProgress(PDFSignerValidationProgressEventParams *e) {...}
Remarks
TBD.
Configuration Settings (PDFSigner Class)

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

| 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).
