Function Documentation

◆ cipher_decrypt_ecb()

int cipher_decrypt_ecb ( cipher_t cipher,
uint8_t *  input,
size_t  length,
uint8_t *  output 
)
Parameters
cipherAlready initialized cipher struct
inputpointer to input data to decrypt
lengthlength of the input data
outputpointer to allocated memory for plaintext data. It has to be of size lengh.

◆ cipher_encrypt_ecb()

int cipher_encrypt_ecb ( cipher_t cipher,
uint8_t *  input,
size_t  length,
uint8_t *  output 
)

Caution each identical block results in an identical encrypted block. Normally you do not want to use ECB.

Parameters
cipherAlready initialized cipher struct
inputpointer to input data to encrypt
lengthlength of the input data
outputpointer to allocated memory for encrypted data. It has to be of size data_len + BLOCK_SIZE - data_len % BLOCK_SIZE.
