Main block cipher trait which defines in-place encryption and decryption over single block

Associated Types

type BlockSize: ArrayLength<u8>

Required Methods

fn encrypt_block(&self, block: &mut GenericArray<u8, Self::BlockSize>)

Encrypt block in-place

fn decrypt_block(&self, block: &mut GenericArray<u8, Self::BlockSize>)

Decrypt block in-place

Provided Methods

fn encrypt_blocks(&self, blocks: &mut [u8])

Encrypt several blocks in-place. Will panic if slice length is not multiple of block size.

Default implementations will just iterate over blocks and will use encrypt_block on them, but some ciphers could utilize instruction level parallelism to speed-up computations

fn decrypt_blocks(&self, blocks: &mut [u8])

Decrypt several blocks in-place. Will panic if slice length is not multiple of block size.

Default implementations will just iterate over blocks and will use decrypt_block on them, but some ciphers could utilize instruction level parallelism to speed-up computations
