Trait block_padding::Padding

pub trait Padding<BlockSize: ArrayLength<u8>> {
    pub fn pad(block: &mut Block<BlockSize>, pos: usize);
    pub fn unpad(block: &Block<BlockSize>) -> Result<&[u8], UnpadError>;
}

Trait for padding messages divided into blocks

Required methods

pub 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 paddin algorithms also panic if they are equal.

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

Unpad data in the block.

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