Struct 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.

impl RawPadding for Iso10126

const TYPE: PadType = PadType::Reversible

Padding type

fn raw_pad(block: &mut [u8], 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 raw_unpad(block: &[u8]) -> Result<&[u8], UnpadError>

Unpad data in the block.
