Encrypts and signs a string.
Syntax
ANSI (Cross Platform) char* EncryptAndSignString(const char* lpszS); Unicode (Windows) LPWSTR EncryptAndSignString(LPCWSTR lpszS);
- (NSString*)encryptAndSignString:(NSString*)S;
#define MID_PGPWRITER_ENCRYPTANDSIGNSTRING 12 SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PGPWriter_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
Use this method to encrypt and sign a string and get the protected message in another string.
Specify encryption keys in EncryptingKeys property, and/or encryption password via Passphrase property. Use SigningKeys to provide the signing keys.
Please note that you might need to provide a passphrase to decrypt your signing key. This can be done via KeyPassphraseNeeded event, or by assigning the passphrase to the key object's Passphrase property.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its 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.
