The PDFSigner class signs PDF documents digitally.

Syntax

secureblackbox.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 Level property (Note: when creating EPES signatures you need to provide the signature PolicyID and PolicyHash 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 Level 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 Invisible 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 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.

Default Value

False

Remarks

If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.

InputBytes Property (PDFSigner Class)

Syntax


public byte[] getInputBytes();


public void setInputBytes(byte[] inputBytes);

Remarks

Syntax


public CertificateList getKnownCertificates();


public void setKnownCertificates(CertificateList knownCertificates);

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 component manually.

The purpose of certificates to be added to this collection is roughly equivalent to that of 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.

KnownCRLs Property (PDFSigner Class)

Additional CRLs for chain validation.

Syntax


public CRLList getKnownCRLs();


public void setKnownCRLs(CRLList knownCRLs);

Remarks

Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.

This property is not available at design time.

KnownOCSPs Property (PDFSigner Class)

Syntax


public boolean isOfflineMode();


public void setOfflineMode(boolean offlineMode);

Default Value

False

Remarks

When working in offline mode, the component restricts itself from using any online revocation information sources, such as CRL or OCSP responders.

Offline mode may be useful if there is a need to verify the completeness of validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.

OutputBytes Property (PDFSigner Class)

Use this property to read the output the class object has produced.

Syntax


public byte[] getOutputBytes();

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

Password Property (PDFSigner Class)

The decryption password.

Syntax


public String getPassword();


public void setPassword(String password);

Default Value

""

Remarks

Use this property to provide the decryption password.

Profile Property (PDFSigner Class)

Specifies a pre-defined profile to apply when creating the signature.

Syntax


public String getProfile();


public void setProfile(String profile);

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

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

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

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

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

Proxy Property (PDFSigner Class)

The proxy server settings.

Syntax


public ProxySettings getProxy();


Remarks

Use this property to tune up the proxy server settings.

This property is read-only.

RevocationCheck Property (PDFSigner Class)

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

Syntax


public int getRevocationCheck();


public void setRevocationCheck(int revocationCheck);


Enumerated values:
  public final static int crcNone = 0;
  public final static int crcAuto = 1;
  public final static int crcAllCRL = 2;
  public final static int crcAllOCSP = 3;
  public final static int crcAllCRLAndOCSP = 4;
  public final static int crcAnyCRL = 5;
  public final static int crcAnyOCSP = 6;
  public final static int crcAnyCRLOrOCSP = 7;
  public final static int crcAnyOCSPOrCRL = 8;

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 (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.

This property is not available at design time.

SigningChain Property (PDFSigner Class)

The signing certificate chain.

Syntax


public CertificateList getSigningChain();


public void setSigningChain(CertificateList signingChain);

Remarks

Use this property to provide the chain for the signing certificate. Use SigningCertificate property, if it is available, to provide the signing certificate itself.

This property is not available at design time.

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

TimestampServer Property (PDFSigner Class)

The address of the timestamping server.

Syntax


public String getTimestampServer();


public void setTimestampServer(String timestampServer);

Default Value

""

Remarks

Use this property to set the address of the TSA (Time Stamping Authority) server to use for timestamping the signature (normal signing) or the document (LTV update).

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

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

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

TLSClientChain Property (PDFSigner Class)

The TLS client certificate chain.

Syntax


public CertificateList getTLSClientChain();


public void setTLSClientChain(CertificateList TLSClientChain);

Remarks

Assign a certificate chain to this property to enable TLS client authentication in the class. Note that the client's end-entity certificate should have a private key associated with it.

This property is not available at design time.

TLSServerChain Property (PDFSigner Class)

The TLS server's certificate chain.

Syntax


public CertificateList getTLSServerChain();


Remarks

Use this property to access the certificate chain sent by the TLS server.

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

TLSSettings Property (PDFSigner Class)

Manages TLS layer settings.

Syntax

This property is read-only.

TrustedCertificates Property (PDFSigner Class)

A list of trusted certificates for chain validation.

Syntax


public CertificateList getTrustedCertificates();


public void setTrustedCertificates(CertificateList trustedCertificates);

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 than that of 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.

ValidationMoment Property (PDFSigner Class)

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

Syntax


public String getValidationMoment();


public void setValidationMoment(String validationMoment);

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 signature creation time, or 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.

Config Method (Pdfsigner Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

DoAction Method (Pdfsigner Class)

Performs an additional action.

Syntax

public String doAction(String actionID, String actionParams);

Remarks

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

Revalidate Method (Pdfsigner Class)

Revalidates a signature in accordance with current settings.

Syntax

public void revalidate(int index);

Remarks

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

Sign Method (Pdfsigner Class)

Signs a PDF document.

Syntax

public void 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.

SignAsyncBegin Method (Pdfsigner Class)

Initiates the asynchronous signing operation.

Syntax

public String 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. 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.

SignAsyncEnd Method (Pdfsigner Class)

Completes the asynchronous signing operation.

Syntax

public void signAsyncEnd(String asyncReply);

Remarks

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

Before calling this method, assign the path to the pre-signed copy of the document obtained from 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. 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.

SignExternal Method (Pdfsigner Class)

Signs the document using an external signing facility.

Syntax

public void 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.

Update Method (Pdfsigner Class)

Updates a signature.

Syntax

public void update(int sigIndex);

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. Set SigIndex to the index 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 InputFile (or InputStream) property. The updated document will be saved to OutputFile (or OutputStream).

ChainElementDownload Event (Pdfsigner Class)

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

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void chainElementDownload(PdfsignerChainElementDownloadEvent e) {}
  ...
}

public class PdfsignerChainElementDownloadEvent {
  public int kind;
  public String certRDN;
  public String CACertRDN;
  public String location;
  public int action;
}

Remarks

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

  ...
  public void chainElementNeeded(PdfsignerChainElementNeededEvent e) {}
  ...
}

public class PdfsignerChainElementNeededEvent {
  public int kind;

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void chainValidated(PdfsignerChainValidatedEvent e) {}
  ...
}

public class PdfsignerChainValidatedEvent {
  public int index;

  public int validationResult;
  public int validationDetails;
}

Remarks

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

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

cvtValid0The chain is valid

cvtValidButUntrusted1The chain is valid, but the root certificate is not trusted

cvtInvalid2The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)

cvtCantBeEstablished3The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void chainValidationProgress(PdfsignerChainValidationProgressEvent e) {}
  ...
}

public class PdfsignerChainValidationProgressEvent {
  public String eventKind;
  public String certRDN;
  public String CACertRDN;
  public int action;
}

Remarks

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

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

veaAuto0Handle the action automatically (the default behaviour)

veaContinue1Accept the request implied by the event (accept the certificate, allow the object retrieval)

veaReject2Reject the request implied by the event (reject the certificate, disallow the object retrieval)

veaAcceptNow3Accept the validated certificate immediately

veaAbortNow4Abort the validation, reject the certificate

DocumentLoaded Event (Pdfsigner Class)

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

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void documentLoaded(PdfsignerDocumentLoadedEvent e) {}
  ...
}

public class PdfsignerDocumentLoadedEvent {
  public boolean cancel;
}

Remarks

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

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

Encrypted Event (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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void encrypted(PdfsignerEncryptedEvent e) {}
  ...
}

public class PdfsignerEncryptedEvent {
  public boolean certUsed;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public boolean needCredential;
  public boolean skipThis;
}

Remarks

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

This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the DecryptionCertificate or Password property (depending on 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 OnEncrypted 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.

Error Event (Pdfsigner Class)

Information about errors during signing/validation.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void error(PdfsignerErrorEvent e) {}
  ...
}

public class PdfsignerErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

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

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

ExternalDecrypt Event (Pdfsigner Class)

Handles remote or external decryption.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void externalDecrypt(PdfsignerExternalDecryptEvent e) {}
  ...
}

public class PdfsignerExternalDecryptEvent {
  public String operationId;
  public String algorithm;
  public String pars;
  public String encryptedData;
  public String data;
}

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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void externalSign(PdfsignerExternalSignEvent e) {}
  ...
}

public class PdfsignerExternalSignEvent {
  public String operationId;
  public String hashAlgorithm;
  public String pars;
  public String data;
  public String signedData;
}

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(); };

Notification Event (Pdfsigner Class)

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

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void notification(PdfsignerNotificationEvent e) {}
  ...
}

public class PdfsignerNotificationEvent {
  public String eventID;
  public String eventParam;
}

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:

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.
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 property 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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void preRenderWidget(PdfsignerPreRenderWidgetEvent e) {}
  ...
}

public class PdfsignerPreRenderWidgetEvent {
  public boolean addAnother;
  public boolean resetAnother;
}

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 being of the same look as the previous one.

SignatureFound Event (Pdfsigner Class)

Signifies the start of signature validation.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void signatureFound(PdfsignerSignatureFoundEvent e) {}
  ...
}

public class PdfsignerSignatureFoundEvent {
  public int index;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public boolean certFound;
  public boolean validateSignature;
  public boolean validateChain;
}

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 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 KnownCertificates property.

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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void signatureValidated(PdfsignerSignatureValidatedEvent e) {}
  ...
}

public class PdfsignerSignatureValidatedEvent {
  public int index;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public int validationResult;
}

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.

svtFailure4General failure

TimestampFound Event (Pdfsigner Class)

Signifies the start of a timestamp validation routine.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void timestampFound(PdfsignerTimestampFoundEvent e) {}
  ...
}

public class PdfsignerTimestampFoundEvent {
  public int index;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public boolean certFound;
  public boolean validateTimestamp;
  public boolean validateChain;
}

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 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 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 SignatureValidationResult and ChainValidationResult 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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void timestampRequest(PdfsignerTimestampRequestEvent e) {}
  ...
}

public class PdfsignerTimestampRequestEvent {
  public String TSA;
  public String timestampRequest;
  public String timestampResponse;
  public boolean suppressDefault;
}

Remarks

Subscribe to this event to be 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 TimestampServer property. Set 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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void timestampValidated(PdfsignerTimestampValidatedEvent e) {}
  ...
}

public class PdfsignerTimestampValidatedEvent {
  public int index;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public String time;
  public int validationResult;
  public int chainValidationResult;
  public int chainValidationDetails;
}

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.

svtFailure4General failure

TLSCertNeeded Event (Pdfsigner Class)

Fires when a remote TLS party requests a client certificate.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void TLSCertNeeded(PdfsignerTLSCertNeededEvent e) {}
  ...
}

public class PdfsignerTLSCertNeededEvent {
  public String host;
  public String CANames;
}

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 (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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void TLSCertValidate(PdfsignerTLSCertValidateEvent e) {}
  ...
}

public class PdfsignerTLSCertValidateEvent {
  public String serverHost;
  public String serverIP;
  public boolean accept;
}

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.

TLSEstablished Event (Pdfsigner Class)

Fires when a TLS handshake with Host successfully completes.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void TLSEstablished(PdfsignerTLSEstablishedEvent e) {}
  ...
}

public class PdfsignerTLSEstablishedEvent {
  public String host;
  public String version;
  public String ciphersuite;
  public byte[] connectionId;
  public boolean abort;
}

Remarks

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

The Version, Ciphersuite, and ConnectionId parameters indicate 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

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void TLSHandshake(PdfsignerTLSHandshakeEvent e) {}
  ...
}

public class PdfsignerTLSHandshakeEvent {
  public String host;
  public boolean abort;
}

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

TLSShutdown Event (Pdfsigner Class)

Reports the graceful closure of a TLS connection.

Syntax

public class DefaultPdfsignerEventListener implements PdfsignerEventListener {
  ...
  public void TLSShutdown(PdfsignerTLSShutdownEvent e) {}
  ...
}

public class PdfsignerTLSShutdownEvent {
  public String host;
}

Remarks

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

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

public CRL();

Creates an empty CRL object.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

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
String

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 pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

KeyID
String

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 KeySecret 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
String

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.

Read more about configuring authentication in the KeyID topic.

Method
int

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

Available options:

asmdPKCS10
asmdPKCS71

Mode
int

Specifies the external cryptography mode.

Available options:

ecmDefaultThe default value (0)
ecmDisabledDo not use DC or external signing (1)
ecmGenericGeneric external signing with OnExternalSign event (2)
ecmDCAuthDCAuth signing (3)
ecmDCAuthJSONDCAuth signing in JSON format (4)

PublicKeyAlgorithm
String

Provide public key algorithm here if the certificate is not available on the pre-signing stage.

Fields

AlgorithmCaption
String

Caption of the signature widget field with information about the signature algorithm.

AlgorithmInfo
String

Information about the algorithm to be shown on the signature widget.

This property contains information about the algorithm to be displayed in the signature widget. Keep this property set to #auto to make the component generate the algorithm text automatically, in the form of "Algorithm/Key size", e.g. "RSA/1024 bits".

BackgroundData
byte[]

Contains/takes the data of the signature widget background bitmap.

Assign the widget background data (in form of JPEG or JPEG2000 bytes) to this property.

BackgroundHeight
String

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

BackgroundImageHeight
int

The height of the background image in pixels.

It is important that this property matches the exact size of the image when custom background is used.

BackgroundImageType
int

The type of the image contained in BackgroundData. JPEG and JPEG2000 format are currently supported.

pwitJPEG20000JPEG 2000 format (supports transparency)
pwitJPEG1standard JPEG format (does not support transparency)
pwitCustom2Custom background format

BackgroundImageWidth
int

The width of the background image in pixels.

It is important that this property matches the exact size of the image when 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
byte[]

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().

BackgroundPosition
String

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.

BackgroundStyle
int

The style of the signature widget background.

pwbsDefault uses the default image, pwbsNoBackground doesn't use background image at all, and pwbsCustom expects the application to provide a custom background image.

pwbsDefault0The default widget background
pwbsNoBackground1No (empty) background
pwbsCustom2Custom background (picture or vector)

BackgroundWidth
String

Use this field to manually adjust the horizontal size of the stretched background picture.

CompressWidgetData
boolean

Whether the signature widget data should be compressed before saving.

CustomAppearance
byte[]

Contains custom widget description in raw PDF graphic operators format.

Use this property to provide a PDF stream describing the widget appearance.

CustomBackgroundContentStream
String

Specifies custom custom background content stream for pwbsCustom BackgroundStyle.

CustomVisualStatusMatrix
String

Defines the custom visual status matrix.

Use of this property makes sense only if a visual status icon is displayed over the signature (ShowVisualStatus). Prior to Acrobat 6, 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
String

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.

FontName
String

Specifies the font name for the signature text.

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

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".

HideDefaultText
boolean

Switch offs generation of any headers for the signature widget.

IgnoreExistingAppearance
boolean

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
boolean

Specifies whether BackgroundMask 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
boolean

Controls whether the signature widget is visible on the page.

PagesToPlaceOn
String

Page numbers on which the signature is shown. This field supports a variety of syntaxes:

  • A single page number: 3
  • A comma-separated list of page numbers: 1,2,5,7
  • The star character (*) indicates that the widget should be placed on all pages in the document
  • The first and last placeholders specify that the signature should be placed on the respective page, independently of its number.

PositionAnchor
int

wroNoRotate0x00001Enabling this option prevents the signature widget from being rotated when the containing document is rotated in a viewing app.

wroNoView0x00002Enabling this option prevents the widget from being displayed when the document is viewed in an app (the widget will still be printed, if configured).

wroNoZoom0x00004Keeps the widget at the same size when the document is zoomed in our out.

wroPrint0x00008Makes the widget printable.

wroReadOnly0x00010Controls the ReadOnly flag of the widget object.

Rotate
int

Specifies the rotation angle of the signature widget in degrees. Values of 0, 90, 180, and 270 are allowed.

ShowDate
boolean

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

ShowVisualStatus
boolean

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."

SignerCaption
String

Specifies the caption for the signer section on the signature widget.

The default value, which is used if the property is set to #auto, is "Signer: ".

SignerInfo
String

Provides custom signer information to put on the signature widget.

ECCurves
String

Defines the elliptic curves to enable.

Extensions
String

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
boolean

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

PreSharedIdentity
String

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

PreSharedKey
String

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

PreSharedKeyCiphersuite
String

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

RenegotiationAttackPreventionMode
int

Selects 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

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.

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

Specifies the background image color space.

Supported values are:

""The default value is empty string or "none". If widget's BackgroundImageType field is JPEG or Custom format then the default value is "RGB".
RGBDeviceRGB (3-component) color space that controls the intensities of red, green, and blue light, the three additive primary colors used in displays.
CMYKDeviceCMYK (4-component) color space that controls the concentrations of cyan, magenta, yellow, and black inks, the four subtractive process colors used in printing.
GrayDeviceGray (1-component) color space that controls the intensity of achromatic light, on a scale from black to white.

BackgroundImageInterpolate:   Specifies the background image interpolation flag.

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 block 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 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 date/time text on the signature widget.

Use this property to specify the font size to be used for 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 component to discourage OCSP responses without an explicit NextUpdate parameter.

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

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

Use this property to specify the empty form field that should be signed. If the default value of "" is assigned to this property and for EmptyFieldIndex property the default value of -1 is assigned, then a new signature field will be created.

EmptySignatureFieldAddRevInfo[Index]:   Specifies if revocation checking should be performed.

This property contains the True value if the viewing application should check the signing certificate revocation info, and include the revocation information within the signature value.

EmptySignatureFieldAlternateName[Index]:   Contains an alternate field name.

EmptySignatureFieldRequiredReasons[Index]:   Specifies the required reasons.

This property contains the required reasons used for signature generation.

EmptySignatureFieldRequiredSubfilters[Index]:   Specifies the required subfilters.

This property contains the list of subfilters required by the signature. A subfilter represents the encoding to use when signing the PDF form.

EmptySignatureFieldTimestampRequired[Index]:   Specifies if the signature should be time-stamped.

This property contains the True value if the signature should be time-stamped.

EmptySignatureFieldTSPURL[Index]:   URL for a TSP server.

noneNo extensions
ESICESIC Extension Level 2
ADBEAdobe Extension Level 8
ADBEIfNotPresentAdobe Extension Level 8 if not present
BothBoth (ESIC and Adobe) extensions

ExtraSpace:   Allows the allocation of extra zero character space in the document behind the signature.

Use this property to allocate extra zero character space in the document behind the signature. The allocated space can be used in future to place a timestamp.

ForceCompleteChainValidation:   Whether to check issuer (CA) certificates when signing certificate is invalid.

Specifies whether to check issuer (CA) certificates when signing certificate is invalid.

ForceCompleteChainValidationForTrusted:   Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors.

Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

GracePeriod:   Specifies a grace period to apply during revocation information checks.

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

HardenedKeyGeneration:   Specifies if hardened Key generation should be used.

Specifies if hardened Key generation should be used when an AES-256 encryption algorithm and password encryption are used.

IgnoreChainLoops:   Whether chain loops should be ignored.

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

IgnoreOCSPNoCheckExtension:   Whether OCSP NoCheck extension should be ignored.

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

IgnoreSystemTrust:   Whether trusted Windows Certificate Stores should be treated as trusted.

Specifies whether, during chain validation, the component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component should trust the certificates residing in the Trusted Root Certification Authorities store.

If IgnoreSystemTrust 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 TrustedCertificates property) are considered trusted.

IgnoreTimestampFailure:   Whether to ignore time-stamping failure during signing.

Specifies whether to ignore time-stamping failure 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 to emulate the verifying environment without actually changing its security settings.

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

This property specifies whether revocation pieces provided via 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 Notification event in case EventID parameter is "SignatureWidgetPrepare" to allow support for multi-widget signatures.

PAdESOptions:   Specifies the PAdES options.

Contains a comma-separated list of values that specifies PAdES options.

Supported values are:

UseSigningCertificateV2When this flag is set, signing certificates V2 will be used.
IncludeAllRevInfoToDSSWhen this flag is set, full set of revocation information will be included to the DSS dictionary.
CreateVRIDictionariesWhen this flag is set, VRI dictionaries will be created. A VRI dictionary references all the validation data that has been used for validating one specific signature.
UseUndefBEREncodingWhen this flag is set, use of ASN.1 tags with undefined size is allowed in the signature.
TolerateMissingSigningCertificate
CompressDSSWhen this flag is set, content in DSS dictionary will be compressed.
CreatePBADCompatibleSignatureWhen this flag is set, the PBAD.PAdES compatible signature is created.

PageInfoCount:   The number of pages.

UseSystemCertificates:   Enables or disables the use of the system certificates.

Use this property to tell chain validation module automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

UseValidationCache:   Enables or disable the use of the product-wide certificate chain validation cache.

Use this property to enable or disable the use of the global chain validation cache. If enabled, the component will consult the product-wide validation cache when validating the signing chains.
