Struct nettle::cipher::Aes256

pub struct Aes256 { /* fields omitted */ }

256 bit variant of the Advanced Encryption Standard (AES, formerly RIJNDAEL) defined in FIPS 197.

Implementations

impl Aes256

pub fn with_inverted_key(encrypt: &Self) -> Self

Creates a new Aes256 instance for decryption that uses the same key as encrypt. The encrypt instance must be configured for encryption. This is faster than calling with_decrypt_key.

Trait Implementations

impl BlockSizeIs16 for Aes256

impl Cipher for Aes256

const BLOCK_SIZE: usize

Block size in bytes.

const KEY_SIZE: usize

Maximal key size in bytes.

fn with_encrypt_key(key: &[u8]) -> Result<Aes256>

Creates a new cipher instance for encryption. The key parameter must have size KEY_SIZE.

fn with_decrypt_key(key: &[u8]) -> Result<Aes256>

Creates a new cipher instance for decryption. The key parameter must have size KEY_SIZE.

fn encrypt(&mut self, dst: &mut [u8], src: &[u8])

Encrypt src into dst. Both must have the same length. That length must be a multiple of BLOCK_SIZE. Blocks are processed in ECB mode.

fn decrypt(&mut self, dst: &mut [u8], src: &[u8])

Decrypt src into dst. Both must have the same length. That length must be a multiple of BLOCK_SIZE. Blocks are processed in ECB mode.

fn context(&mut self) -> *mut c_void

Returns a pointer to the C context struct of the cipher instance. Used internally by block modi.

fn raw_encrypt_function() -> RawCipherFunctionPointer

Pointer to the *_encrypt C function. Used internally for block modi.

fn raw_decrypt_function() -> RawCipherFunctionPointer

Pointer to the *_decrypt C function. Used internally for block modi.
