UnwrapKey Method

Unwraps a symmetric key.

Syntax

int UnwrapKey(const QString& qsKeyName, const QString& qsAlgorithm);

Remarks

This method unwraps (i.e., decrypts) a symmetric key using the key specified by KeyName and the given Algorithm.

This method functions exactly the same way as the Decrypt method, except that it requires the keys/unwrapKey permission instead of the keys/decrypt permission. Refer to the Decrypt method's documentation for more information.

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.)
