impl<B: ArrayLength<u8>> Padding<B> for AnsiX923

const TYPE: PadType = PadType::Reversible

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.
