DecryptAndVerifySignature Method

Decrypts and verifies the signature of the current message.

Syntax

ANSI (Cross Platform)
int DecryptAndVerifySignature();

Unicode (Windows)
INT DecryptAndVerifySignature();
- (void)decryptAndVerifySignature;
#define MID_SIMAP_DECRYPTANDVERIFYSIGNATURE 11

IPWORKSSMIME_EXTERNAL int IPWORKSSMIME_CALL IPWorksSMIME_SIMAP_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

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 (C++)

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.)
