Trait block_cipher::BlockCipher

pub trait BlockCipher {
    type BlockSize: ArrayLength<u8>;
    type ParBlocks: ArrayLength<Block<Self>>;
    fn encrypt_block(&self, block: &mut Block<Self>);
    fn decrypt_block(&self, block: &mut Block<Self>);

    fn encrypt_blocks(&self, blocks: &mut ParBlocks<Self>) { ... }
    fn decrypt_blocks(&self, blocks: &mut ParBlocks<Self>) { ... }
}

The trait which defines in-place encryption and decryption over single block or several blocks in parallel.

Associated Types

type BlockSize: ArrayLength<u8>

Size of the block in bytes

type ParBlocks: ArrayLength<Block<Self>>

Number of blocks which can be processed in parallel by cipher implementation

Required methods

fn encrypt_block(&self, block: &mut Block<Self>)

Encrypt block in-place

fn decrypt_block(&self, block: &mut Block<Self>)

Decrypt block in-place

Provided methods

fn encrypt_blocks(&self, blocks: &mut ParBlocks<Self>)

Encrypt several blocks in parallel using instruction level parallelism if possible.

If ParBlocks equals to 1 it’s equivalent to encrypt_block.

fn decrypt_blocks(&self, blocks: &mut ParBlocks<Self>)

Decrypt several blocks in parallel using instruction level parallelism if possible.

If ParBlocks equals to 1 it’s equivalent to decrypt_block.
