The .Fa direction (which may be .Dv DIR_ENCRYPT or .Dv 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 .Nm sources, .Dv BINARY_KEY_MATERIAL . .Sh RETURN VALUES The .Fn rijndael_makeKey function will return .Dv BAD_KEY_INSTANCE if a .Dv NULL .Fa key is passed, .Dv BAD_KEY_DIR if .Fa direction is not .Dv DIR_ENCRYPT or .Dv DIR_DECRYPT , .Dv BAD_KEY_MAT if the key materials are not a hexadecimal string (and binary keys are not set), and .Dv TRUE otherwise. .Sh AUTHORS .An Mark R V Murray
