The MessageVerifier component verifies digital signatures of data stored in the PKCS#7 format.

Syntax

TsbxMessageVerifier

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.

 
 Copy
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

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

Data Type

Integer

CertBytes Property (MessageVerifier Component)

Returns the raw certificate data in DER format.

Syntax

__property DynamicArray CertBytes[int CertIndex] = { read=FCertBytes };

Remarks

Returns the raw certificate data in DER format.

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

CertCA Property (MessageVerifier Component)

Indicates whether the certificate has a CA capability.

Syntax

__property bool CertCA[int CertIndex] = { read=FCertCA };

Default Value

false

Remarks

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

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

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 (MessageVerifier Component)

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

Syntax

__property DynamicArray CertCAKeyID[int CertIndex] = { read=FCertCAKeyID };

Remarks

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

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

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

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

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

Data Type

Byte Array

CertCertType Property (MessageVerifier Component)

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

Syntax

__property TsbxMessageVerifierCertCertTypes CertCertType[int CertIndex] = { read=FCertCertType };

enum TsbxMessageVerifierCertCertTypes {
  ctUnknown=0,
  ctX509Certificate=1,
  ctX509CertificateRequest=2
};

Default Value

ctUnknown

Remarks

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

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

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

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

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

Data Type

Integer

Contains a list of locations of CRL distribution points used to check this certificate's validity.

Syntax

__property String CertCRLDistributionPoints[int CertIndex] = { read=FCertCRLDistributionPoints };

Default Value

""

Remarks

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

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

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

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 (MessageVerifier Component)

Specifies the elliptic curve associated with the certificate's public key.

Syntax

__property String CertCurve[int CertIndex] = { read=FCertCurve };

Default Value

""

Remarks

Syntax

__property String CertFingerprint[int CertIndex] = { read=FCertFingerprint };

Default Value

""

Remarks

Contains the fingerprint (a hash imprint) of this certificate.

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

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 (MessageVerifier Component)

Contains an associated alias (friendly name) of the certificate.

Syntax

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

Default Value

""

Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

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

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

Data Type

String

CertHandle Property (MessageVerifier Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Syntax

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.

 
 Copy
  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.

Default Value

0

Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the CertPublicKeyBytes or CertPrivateKeyBytes property would typically contain auxiliary values, and therefore be longer.

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

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

Data Type

Integer

CertKeyFingerprint Property (MessageVerifier Component)

Contains identifiers (OIDs) of the applicable certificate policies.

Syntax

__property String CertPolicyIDs[int CertIndex] = { read=FCertPolicyIDs };

Default Value

""

Remarks

Contains identifiers (OIDs) of the applicable certificate policies.

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

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

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

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 (MessageVerifier Component)

Verifies a detached signature.

Syntax

void __fastcall VerifyDetached();
