Detailed Description

Primitive.

AES (Advanced Encryption Standard) is a block cipher. It has a 128-bit block size and three possible key sizes, namely 128, 192 and 256 bits. It is based on the Rijndael cipher and was selected as the official encryption standard on November 2001 (FIPS 197).

Return values

ORDO_KEY_LEN	if the key length is not 16, 24, or 32 (bytes).
