Required methods

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

Encrypt block in-place

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

Decrypt block in-place

Provided methods

pub 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.

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

Encrypt a slice of blocks, leveraging parallelism when available.

pub 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.

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

Decrypt a slice of blocks, leveraging parallelism when available.
