Expand description

Decrypt 14 rounds of unsigned 8-bit integers in `input` using 256-bit AES key specified in the 512-bit key handle `handle`. Store the resulting unsigned 8-bit integers into the corresponding elements of `output`. Returns `0` if the operation was successful, and `1` if the operation failed due to a handle violation.
