helper

Perform AES-128-CBC encryption with residual block termination.

Parameters

key	AES key, pointer to TS2_AES_KEY_LENGTH bytes of data.
iv	AES IV, pointer to TS2_AES_CBC_IV_SIZE bytes of data.
data	the input data array.
data_size	the size of the input array in bytes.
enc_data	the output array. Must have at least data_size bytes.

helper

Compute a message HMAC.

Parameters

algorithm	the digest algorithm to use.
key	the HMAC key address.
key_size	the HMAC key size in bytes.
data	the message data address.
data_size	the size of the data in bytes.
mac	address of the output array. There must be at least as much memory allocated for the mac array as is needed by the requested digest algorithm. For example, 20 bytes for SHA1, i.e. TS2_SHA1_DIGEST_SIZE bytes for algorithm equal to TS2_DIGEST_SHA1.
