Struct Aes256 

pub struct Aes256 { /* private fields */ }

AES-256 block cipher.

Encrypts and decrypts independent 16-byte blocks (ECB). This is the raw block cipher, not a mode of operation: use it as a building block (key wrapping, KDFs) and not to encrypt data directly.

Implementations

impl Aes256

pub const KEY_SIZE: usize = 32

Size of the key, in bytes.

pub const BLOCK_SIZE: usize = 16

Size of a block, in bytes.

pub fn new(key: &[u8; 32]) -> Self

Initialize with key.

pub fn encrypt_block(&self, block: &mut [u8; 16])

Encrypt one block in place.

pub fn decrypt_block(&self, block: &mut [u8; 16])

Decrypt one block in place.

pub fn encrypt_blocks(&self, blocks: &mut [u8]) -> Result<(), Error>

Encrypt a whole number of blocks in place.

pub fn decrypt_blocks(&self, blocks: &mut [u8]) -> Result<(), Error>

Decrypt a whole number of blocks in place.

pub fn encrypt_blocks_to( &self, input: &[u8], output: &mut [u8], ) -> Result<(), Error>

Encrypt a whole number of blocks from input to output.

pub fn decrypt_blocks_to( &self, input: &[u8], output: &mut [u8], ) -> Result<(), Error>

Decrypt a whole number of blocks from input to output.
