Struct block_padding::Iso10126

pub struct Iso10126;

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);

impl<B: ArrayLength<u8>> Padding<B> for Iso10126

const TYPE: PadType

Padding type

fn pad(block: &mut Block<B>, pos: usize)

Pads block filled with data up to pos (i.e length of a message stored in the block is equal to pos).

fn unpad(block: &Block<B>) -> Result<&[u8], UnpadError>

Unpad data in the block.

fn unpad_blocks(blocks: &[Block<BlockSize>]) -> Result<&[u8], UnpadError>

Unpad data in the blocks.
