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

Required Associated Types

type BlockSize: ArrayLength<u8>

Size of the block in bytes

type ParBlocks: ArrayLength<GenericArray<u8, Self::BlockSize>>

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

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 GenericArray<GenericArray<u8, Self::BlockSize>, Self::ParBlocks>, )

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

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

fn encrypt_slice(&self, blocks: &mut [GenericArray<u8, Self::BlockSize>])

Encrypt a slice of blocks, leveraging parallelism when available.

fn decrypt_blocks( &self, blocks: &mut GenericArray<GenericArray<u8, Self::BlockSize>, Self::ParBlocks>, )

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

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

fn decrypt_slice(&self, blocks: &mut [GenericArray<u8, Self::BlockSize>])

Decrypt a slice of blocks, leveraging parallelism when available.
