Function Documentation
◆ cipher_decrypt_ecb()
| int cipher_decrypt_ecb | ( | const cipher_t * | cipher, |
| const uint8_t * | input, | ||
| size_t | length, | ||
| uint8_t * | output | ||
| ) |
Decrypts data of arbitrary length in ecb mode.
- Parameters
-
cipher Already initialized cipher struct input pointer to input data to decrypt length length of the input data output pointer to allocated memory for plaintext data. It has to be of size length.
- Returns
- Length of decrypted data on a successful decryption
- A negative error code if something went wrong
◆ cipher_encrypt_ecb()
| int cipher_encrypt_ecb | ( | const cipher_t * | cipher, |
| const uint8_t * | input, | ||
| size_t | length, | ||
| uint8_t * | output | ||
| ) |
Encrypt data of arbitrary length in ecb mode.
Caution each identical block results in an identical encrypted block. Normally you do not want to use ECB.
- Parameters
-
cipher Already initialized cipher struct input pointer to input data to encrypt length length of the input data output pointer to allocated memory for encrypted data. It has to be of size data_len + BLOCK_SIZE - data_len % BLOCK_SIZE.
- Returns
- Length of encrypted data on a successful encryption
- A negative error code if something went wrong
