rijndael_blockDecrypt,
rijndael_padDecrypt —
AES encryption
SYNOPSIS¶
#include
<sys/types.h>
#include
<crypto/rijndael.h>
int
rijndael_makeKey(
keyInstance
*key,
uint8_t direction,
int keyLen,
char
*keyMaterial);
int
rijndael_cipherInit(
cipherInstance
*cipher,
uint8_t mode,
char *IV);
int
rijndael_blockEncrypt(
cipherInstance
*cipher,
keyInstance *key,
uint8_t *input,
int inputLen,
uint8_t *outBuffer);
int
rijndael_padEncrypt(
cipherInstance
*cipher,
keyInstance *key,
uint8_t *input,
int inputOctets,
uint8_t *outBuffer);
int
rijndael_blockDecrypt(
cipherInstance
*cipher,
keyInstance *key,
uint8_t *input,
int inputLen,
uint8_t *outBuffer);
int
rijndael_padDecrypt(
cipherInstance
*cipher,
keyInstance *key,
uint8_t *input,
int inputOctets,
uint8_t *outBuffer);
DESCRIPTION¶
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.
RETURN VALUES¶
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.
