DecryptAndVerifySignature Method
Decrypts and verifies the signature of the current message.
Syntax
int DecryptAndVerifySignature();
Remarks
This method attempts to both decrypt and verify the signature of the message. All of the properties affected by calling the Decrypt and VerifySignature methods are affected in the same manner.
NOTE: This function does not attempt to check the validity of the signing certificate itself.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
