[−][src]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>>`

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.
