Method Detail

callback

WinCrypt.CERT_CONTEXT.ByReference callback(Pointer pvGetArg,
                                           int dwCertEncodingType,
                                           WinCrypt.CERT_INFO pSignerId,
                                           WinCrypt.HCERTSTORE hMsgCertStore)

Parameters:

pvGetArg - A pointer to user-defined data passed on to the verification function as specified in the CRYPT_VERIFY_MESSAGE_PARA structure.

dwCertEncodingType - Specifies the type of encoding used. It is always acceptable to specify both the certificate and message encoding types by combining them with a bitwise-OR operation as shown in the following example:

X509_ASN_ENCODING | PKCS_7_ASN_ENCODING

Currently defined encoding types are:

• X509_ASN_ENCODING
• PKCS_7_ASN_ENCODING

pSignerId - A pointer to a CERT_INFO structure containing the issuer and serial number. Can be NULL if there is no content or signer.

hMsgCertStore - A handle to the certificate store containing all the certificates and CRLs in the signed message.

Returns:

Pointer to a read-only WinCrypt.CERT_CONTEXT if a signer certificate is found, null if the function fails.
