Remarks

PKCS#7 (Public Key Cryptography Standard #7) is a common format used to store encrypted and signed data. It is used by a variety of protocols, including S/MIME and CMS.

MessageVerifier can process signed data in PKCS#7 SignedData and AuthenticatedData subformats. RSA, ECDSA, and EdDSA algorithms are supported.

Setting up and using MessageVerifier is easy:

• Set up your source and destination via InputFile (InputBytes) and OutputFile (OutputBytes) properties. For detached signatures, provide the signed data separately via DataFile (DataBytes).
• For the SignedData-type signatures (most commonly used), add the public part of the signing certificate to the Certificates collection. This step may be unnecessary, as it is typical for signers to include their certificates in the signature.
• For the AuthenticatedData-type signature, add the recipient's (i.e. your) certificate, with its private key, to Certificates collection.
• Call Verify or VerifyDetached, as appropriate, to execute the validation operation.
• Post-validation, you can get access to signature properties, such as ClaimedSigningTime, SignedAttributes, and UnsignedAttributes.

Note that MessageVerifier can only work with binary PKCS#7-compliant and PKCS#1-compliant signatures. To process S/MIME-signed emails, see MailReader. To process PGP signatures, see PGPReader.

MessageVerifier is a simplified form of CAdESVerifier. Both classes work with PKCS#7 signed messages. CAdESVerifier, however, provides support for advanced (CAdES) signatures, including long-term validity, archival, and full chain validation capabilities. These advanced capabilities are absent from MessageVerifier, which is only capable of processing basic PKCS#7 signatures without any chain of trust validation. MessageVerifier verifier = new MessageVerifier(); // Select the file which contains the signed message verifier.setInputFile("signedMessage.bin"); if (verifier.checkSignatureType() == Constants.stPKCS7Detached) { // To verify a detached signature, we need // to provide both the signature and the original data verifier.setDataFile("message.txt"); verifier.verifyDetached(); } else { // To verify an enveloping signature, we need // to provide the location to extract the data verifier.setOutputFile("output.txt"); verifier.verify(); } System.out.println("Validation result: " + verifier.getSignatureValidationResult() + "\n" + "Signing time: " + verifier.getValidatedSigningTime() + "\n" + "TSA certificate: " + verifier.getSigningCertificate().getSubjectRDN()); // Output: // // Validation result: 0 // 0 == svtValid // Signing time: 2024-05-16 15:18:35 // TSA certificate: /CN=Test Certificate

Object Oriented Interface

public function getCertCA($certindex);

Procedural Interface

secureblackbox_messageverifier_get($res, 3 , $certindex);

Default Value

false

Remarks

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

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

Data Type

Boolean

CertCAKeyID Property (SecureBlackbox_MessageVerifier Class)

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

Object Oriented Interface

public function getCertCAKeyID($certindex);

Procedural Interface

secureblackbox_messageverifier_get($res, 4 , $certindex);

Remarks

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

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the CertSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

Data Type

Byte Array

CertCertType Property (SecureBlackbox_MessageVerifier Class)

Object Oriented Interface

public function getCertCertType($certindex);

Procedural Interface

secureblackbox_messageverifier_get($res, 5 , $certindex);

Default Value

0

Remarks

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

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager class to load or create new certificate and certificate requests objects.

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

Data Type

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

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

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

Data Type

String

CertCurve Property (SecureBlackbox_MessageVerifier Class)

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

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

Data Type

String

CertFriendlyName Property (SecureBlackbox_MessageVerifier Class)

Object Oriented Interface

public function getCertFriendlyName($certindex);

Procedural Interface

secureblackbox_messageverifier_get($res, 9 , $certindex);

Default Value

''

Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation.

Procedural Interface

secureblackbox_messageverifier_get($res, 10 , $certindex);

Default Value

0

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

The $certindex parameter specifies the index of the item in the array. The size of the array is controlled by the CertCount property.

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

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 (SecureBlackbox_MessageVerifier Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_messageverifier_do_doaction($res, $actionid, $actionparams);

Remarks

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

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

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

Common ActionIDs:

Reset Method (SecureBlackbox_MessageVerifier Class)

Resets the class settings.

Object Oriented Interface

public function doReset();

Procedural Interface

secureblackbox_messageverifier_do_reset($res);

Remarks

Reset is a generic method available in every class.

Verify Method (SecureBlackbox_MessageVerifier Class)

Verifies digitally signed data.

Object Oriented Interface

public function doVerify();

Procedural Interface

secureblackbox_messageverifier_do_verify($res);

Remarks

PKCS#7 and its successor, CMS, support two types of signatures: (1) enveloping signatures, where the signed data and its signature are combined in the same message, and (2) detached signatures, where the signature is stored as a separate entity. This method verifies enveloped signatures and extracts data contained in them. Use VerifyDetached to verify detached signatures.

This method expects the enveloping signature to be provided via InputFile or InputStream properties.

Note that this method only checks the integrity of the signature, i.e., that it is signed with the claimed certificate and has not been altered. It does not validate the signing certificate chain. To validate the certificate chain, either use CertificateValidator component together with MessageVerifier, or consider using CAdESVerifier component instead.

VerifyDetached Method (SecureBlackbox_MessageVerifier Class)

Verifies a detached signature.

Object Oriented Interface

public function doVerifyDetached();

Procedural Interface

secureblackbox_messageverifier_do_verifydetached($res);

Remarks

Use this method to verify detached signatures. Pass the signature via InputFile (or InputStream) property, and the original data via DataFile (DataStream).

public function fireError($param);

Procedural Interface

secureblackbox_messageverifier_register_callback($res, 1, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

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

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Messages section.

Notification Event (SecureBlackbox_MessageVerifier Class)

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

Object Oriented Interface

public function fireNotification($param);

Procedural Interface

secureblackbox_messageverifier_register_callback($res, 2, array($this, 'fireNotification'));

Parameter List

 'eventid'
 'eventparam'

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

RecipientFound Event (SecureBlackbox_MessageVerifier Class)

Fires to report a message addressee parameters.

Object Oriented Interface

public function fireRecipientFound($param);

Procedural Interface

secureblackbox_messageverifier_register_callback($res, 3, array($this, 'fireRecipientFound'));

Parameter List

 'issuerrdn'
 'serialnumber'
 'subjectkeyid'
 'certfound'

Remarks

This event is fired for each addressee the message is encrypted for. It may fire several times in a row if the message is encrypted for more than one recipient.

The IssuerRDN, SerialNumber, and SubjectKeyID parameters to identify the recipient's certificate. CertFound indicates if the specified certificate has been located in Certificates collection. If it wasn't, you might want to look up the certificate manually, and add it to the collection inside the event handler.

SignatureFound Event (SecureBlackbox_MessageVerifier Class)

Signifies the start of signature validation.

Object Oriented Interface

public function fireSignatureFound($param);

Procedural Interface

secureblackbox_messageverifier_register_callback($res, 4, array($this, 'fireSignatureFound'));

Parameter List

 'issuerrdn'
 'serialnumber'
 'subjectkeyid'
 'certfound'
 'validatesignature'
 '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 parameter is set to True if the class has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

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

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

SignatureValidated Event (SecureBlackbox_MessageVerifier Class)

Marks the completion of the signature validation routine.

Object Oriented Interface

public function fireSignatureValidated($param);

Procedural Interface

secureblackbox_messageverifier_register_callback($res, 5, array($this, 'fireSignatureValidated'));
