Struct Decipher 

pub struct Decipher { /* private fields */ }

Main AES-CBC Decipher structure.

Usage:

extern crate dumb_crypto;

use::dumb_crypto::aes::BLOCK_SIZE;
use::dumb_crypto::aes_cbc::Decipher;

let iv = [
    0x4c, 0xb4, 0x52, 0xd6, 0x78, 0xca, 0x94, 0x61,
    0x92, 0xcd, 0xc6, 0x91, 0xb7, 0xab, 0x61, 0x76,
];
let key: [u8; 16] = [
    0x69, 0xc2, 0xa9, 0xe6, 0x2b, 0x61, 0x30, 0x60,
    0xc9, 0x79, 0x7b, 0xdc, 0xe4, 0xf6, 0x40, 0x8e,
];
let mut decipher = Decipher::new(iv);
decipher.init(&key).unwrap();

let mut cleartext = decipher.write(&[
    0x98, 0xba, 0x8e, 0x07, 0x5b, 0xcf, 0xa7, 0xb9,
    0x3a, 0xbe, 0x45, 0x3a, 0xb1, 0x84, 0xdc, 0x68,
]).unwrap();
cleartext.append(&mut decipher.flush().unwrap());

Implementations

impl Decipher

pub fn new(iv: [u8; 16]) -> Self

Create new instance of AES-CBC Decipher

iv - Initialization Vector (this better be a very random value)

pub fn init(&mut self, key: &[u8]) -> Result<(), AESError>

Initialize instance of AES-CBC Decipher

key - AES Key. Must be either 128, 192, or 256 bits.

pub fn write(&mut self, b: &[u8]) -> Result<Vec<u8>, DecipherError>

Decrypt data

pub fn flush(&mut self) -> Result<Vec<u8>, DecipherError>

Decrypt and return final cleartext data
