  Public ReadOnly Property SerialNumber As Byte()
  Public ReadOnly Property SubjectKeyID As Byte()
  Public ReadOnly Property CertFound As Boolean
  Public Property ValidateSignature As Boolean
  Public Property ValidateChain As Boolean
End Class

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 component 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 (XMLVerifier Component)

  Public ReadOnly Property SigIndex As Integer
  Public ReadOnly Property IssuerRDN As String
  Public ReadOnly Property SerialNumber As Byte()
  Public ReadOnly Property SubjectKeyID As Byte()
  Public ReadOnly Property ValidationResult As Integer
End Class

Remarks

This event is fired when the complete XML signature validation process is finished. IssuerRDN returns the name of the signature issuer, SerialNumber identifies the signing certificate, SubjectKeyID contains the key identifier (SecureBlackbox uses SHA-1 hash algorithm output as key identifiers). Finally, ValidationResult specifies whether signature is valid or not:
