tc_aes128_set_encrypt_key() function
Set AES-128 encryption key Uses key k to initialize s
Syntax
Implemented in ![]()
aes_encrypt.c:70
Return value
returns TC_CRYPTO_SUCCESS (1) returns TC_CRYPTO_FAIL (0) if: s == NULL or k == NULL
Notes
This implementation skips the additional steps required for keys larger than 128 bits, and must not be used for AES-192 or AES-256 key schedule -- see FIPS 197 for details

Description
AES-128 Encryption procedure Encrypts contents of in buffer into out buffer under key; schedule s
AES-128 Encryption procedure Decrypts in buffer into out buffer under key schedule s
Variation of CBC-MAC mode used in CCM.
Configures the CMAC state to use the given AES key
Variation of CBC-MAC mode used in CCM.
Set the AES-128 decryption key Uses key k to initialize s
CTR mode encryption/decryption procedure. CTR mode encrypts (or decrypts) inlen bytes from in buffer into out buffer
CCM configuration procedure
CBC encryption procedure CBC encrypts inlen bytes of the in buffer into the out buffer using the encryption key schedule provided, prepends iv to out
CBC decryption procedure CBC decrypts inlen bytes of the in buffer into the out buffer using the provided encryption key schedule
Variation of CTR mode used in CCM. The CTR mode used by CCM is slightly different than the conventional CTR mode (the counter is increased before encryption, instead of after encryption). Besides, it is assumed that the counter is stored in the last 2 bytes of the nonce.
