The rijndael_makeKey function is used to set up the key schedule in key. The 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 keyLen, and must be 128, 192 or 256. The actual key is supplied in the buffer pointed to by 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 rijndael_makeKey sources, BINARY_KEY_MATERIAL.


The rijndael_makeKey function will return BAD_KEY_INSTANCE if a NULL key is passed, BAD_KEY_DIR if 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.
