Remarks

Use this method to sign a file and store the signed message in another file.

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 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.)
