Function rc5_cipher::rc5::decode

pub fn decode<W, const T: usize>(
    key: Vec<u8>,
    ct: Vec<u8>
) -> Result<Vec<u8>, Error>where
    W: Unsigned,
    for<'a> &'a [u8]: TryInto<W::Array>,

Decrypts a ciphertext ct and returns a plaintext pt. The ct should have length 2 * w = 2 * bytes(W)

W: is the data type. Currently supported: u8, u16, u32, u64, u128 T: is the key expansion length T = 2 * (r + 1) being r number of rounds. T should be even.

Example:

use rc5_cipher::decode;

let key = vec![0x00, 0x01, 0x02, 0x03];
let pt  = vec![0x00, 0x01];
let ct  = vec![0x21, 0x2A];
let res = decode::<u8, 26>(key, ct.clone()).unwrap();

assert!(&pt[..] == &res[..]);
