Trait for padding messages divided into blocks

Required Associated Constants

const TYPE: PadType

Padding type

Required Methods

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

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

Panics

If pos is bigger than BlockSize. Most padding algorithms also panic if they are equal.

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

Unpad data in the block.

Returns Err(UnpadError) if the block contains malformed padding.

Provided Methods

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

Unpad data in the blocks.

Returns Err(UnpadError) if the block contains malformed padding.

Object Safety

This trait is not object safe.
