DESCRIPTION
The
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
sources,
BINARY_KEY_MATERIAL
RETURN VALUES
The
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_DECRYPTBAD_KEY_MAT
if the key materials are not a hexadecimal string
(and binary keys are not set),
and
TRUE
otherwise.
