[][src]Enum block_padding::ZeroPadding

pub enum ZeroPadding {}

Pad block with zeros.

use block_padding::{ZeroPadding, Padding};

let msg = b"test";
let n = msg.len();
let mut buffer = [0xff; 16];
buffer[..n].copy_from_slice(msg);
let padded_msg = ZeroPadding::pad(&mut buffer, n, 8).unwrap();
assert_eq!(padded_msg, b"test\x00\x00\x00\x00");
assert_eq!(ZeroPadding::unpad(&padded_msg).unwrap(), msg);
let padded_msg = ZeroPadding::pad(&mut buffer, n, 2).unwrap();
assert_eq!(padded_msg, b"test");
assert_eq!(ZeroPadding::unpad(&padded_msg).unwrap(), msg);

Note that zero padding may not be reversible if the original message ends with one or more zero bytes.
