Struct block_padding::Iso10126
source · pub struct Iso10126;
Expand description
Pad block with arbitrary bytes ending with value equal to the number of bytes added.
A variation of PKCS#7 that is less strict when decoding.
use block_padding::{Iso10126, Padding};
use generic_array::{GenericArray, typenum::U8};
let msg = b"test";
let pos = msg.len();
let mut block: GenericArray::<u8, U8> = [0xff; 8].into();
block[..pos].copy_from_slice(msg);
Iso10126::pad(&mut block, pos);
assert_eq!(&block[..], b"test\x04\x04\x04\x04");
let res = Iso10126::unpad(&block).unwrap();
assert_eq!(res, msg);
