XTEA CBC cipher function.
- Parameters:
-
ctx XTEA context mode MBEDTLS_XTEA_ENCRYPT or MBEDTLS_XTEA_DECRYPT length the length of input, multiple of 8 iv initialization vector for CBC mode input input block output output block
- Returns:
- 0 if successful, MBEDTLS_ERR_XTEA_INVALID_INPUT_LENGTH if the length % 8 != 0
