DESCRIPTION

The Fn rijndael_makeKey function is used to set up the key schedule in Fa key . The Fa direction (which may be DIR_ENCRYPT or DIR_DECRYPT specifies the intended use of the key. The length of the key (in bits) is given in Fa keyLen , and must be 128, 192 or 256. The actual key is supplied in the buffer pointed to by Fa keyMaterial . This material may be raw binary data, or an ASCII string containing a hexadecimal rendition of the raw binary data, dependent on a compile-time option in the ifconfig sources, BINARY_KEY_MATERIAL

RETURN VALUES

The Fn rijndael_makeKey function will return BAD_KEY_INSTANCE if a NULL Fa key is passed, BAD_KEY_DIR if Fa direction is not DIR_ENCRYPT or DIR_DECRYPT BAD_KEY_MAT if the key materials are not a hexadecimal string (and binary keys are not set), and TRUE otherwise.
