Function Documentation

int camellia_crypt_cbc ( camellia_context *  ctx,
int  mode,
size_t  length,
unsigned char  iv[16],
const unsigned char *  input,
unsigned char *  output 
)

CAMELLIA-CBC buffer encryption/decryption Length should be a multiple of the block size (16 bytes)

Parameters:
ctxCAMELLIA context
modeCAMELLIA_ENCRYPT or CAMELLIA_DECRYPT
lengthlength of the input data
ivinitialization vector (updated after use)
inputbuffer holding the input data
outputbuffer holding the output data
Returns:
0 if successful, or POLARSSL_ERR_CAMELLIA_INVALID_INPUT_LENGTH

Definition at line 543 of file camellia.c.

int camellia_crypt_cfb128 ( camellia_context *  ctx,
int  mode,
size_t  length,
size_t *  iv_off,
unsigned char  iv[16],
const unsigned char *  input,
unsigned char *  output 
)

CAMELLIA-CFB128 buffer encryption/decryption.

Note: Due to the nature of CFB you should use the same key schedule for both encryption and decryption. So a context initialized with camellia_setkey_enc() for both CAMELLIA_ENCRYPT and CAMELLIE_DECRYPT.

Parameters:
ctxCAMELLIA context
modeCAMELLIA_ENCRYPT or CAMELLIA_DECRYPT
lengthlength of the input data
iv_offoffset in IV (updated after use)
ivinitialization vector (updated after use)
inputbuffer holding the input data
outputbuffer holding the output data
Returns:
0 if successful, or POLARSSL_ERR_CAMELLIA_INVALID_INPUT_LENGTH

Definition at line 597 of file camellia.c.

int camellia_crypt_ctr ( camellia_context *  ctx,
size_t  length,
size_t *  nc_off,
unsigned char  nonce_counter[16],
unsigned char  stream_block[16],
const unsigned char *  input,
unsigned char *  output 
)

CAMELLIA-CTR buffer encryption/decryption.

Warning: You have to keep the maximum use of your counter in mind!

Note: Due to the nature of CTR you should use the same key schedule for both encryption and decryption. So a context initialized with camellia_setkey_enc() for both CAMELLIA_ENCRYPT and CAMELLIA_DECRYPT.

Parameters:
ctxCAMELLIA context
lengthThe length of the data
nc_offThe offset in the current stream_block (for resuming within current cipher stream). The offset pointer to should be 0 at the start of a stream.
nonce_counterThe 128-bit nonce and counter.
stream_blockThe saved stream-block for resuming. Is overwritten by the function.
inputThe input data stream
outputThe output data stream
Returns:
0 if successful

Definition at line 645 of file camellia.c.

int camellia_crypt_ecb ( camellia_context *  ctx,
int  mode,
const unsigned char  input[16],
unsigned char  output[16] 
)

CAMELLIA-ECB block encryption/decryption.

Parameters:
ctxCAMELLIA context
modeCAMELLIA_ENCRYPT or CAMELLIA_DECRYPT
input16-byte input block
output16-byte output block
Returns:
0 if successful

Definition at line 480 of file camellia.c.

int camellia_self_test ( int  verbose )

Checkup routine.

Returns:
0 if successful, or 1 if the test failed

Definition at line 881 of file camellia.c.

int camellia_setkey_dec ( camellia_context *  ctx,
const unsigned char *  key,
unsigned int  keysize 
)

CAMELLIA key schedule (decryption)

Parameters:
ctxCAMELLIA context to be initialized
keydecryption key
keysizemust be 128, 192 or 256
Returns:
0 if successful, or POLARSSL_ERR_CAMELLIA_INVALID_KEY_LENGTH

Definition at line 428 of file camellia.c.

int camellia_setkey_enc ( camellia_context *  ctx,
const unsigned char *  key,
unsigned int  keysize 
)

CAMELLIA key schedule (encryption)

Parameters:
