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.
Input and Output Properties
The class will determine the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
When a valid source is found the search stops. The order in which the output properties are checked is as follows:
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.
The headers of the input message (if any) will be read from InputMessageHeaders or InputMessageHeadersString.
The headers of the resulting message will be available in the OutputMessageHeaders and OutputMessageHeadersString properties.
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.)
