[][src]Enum block_padding::Pkcs7

pub enum Pkcs7 {}

Pad block with bytes with value equal to the number of bytes added.

PKCS#7 described in the RFC 5652.

use block_padding::{Pkcs7, Padding};

let msg = b"test";
let n = msg.len();
let mut buffer = [0xff; 8];
let padded_msg = Pkcs7::pad(&mut buffer, n, 8).unwrap();
assert_eq!(padded_msg, b"test\x04\x04\x04\x04");
assert_eq!(Pkcs7::unpad(&padded_msg).unwrap(), msg);
let padded_msg = Pkcs7::pad(&mut buffer, n, 2).unwrap();
assert_eq!(padded_msg, b"test\x02\x02");
assert_eq!(Pkcs7::unpad(&padded_msg).unwrap(), msg);
let mut buffer = [0xff; 5];
assert!(Pkcs7::pad(&mut buffer, 4, 2).is_err());

In addition to conditions stated in the Padding trait documentation, pad_block will return PadError if block.len() > 255, and in case of pad if block_size > 255.
