Struct Sm4 

pub struct Sm4 { /* private fields */ }

SM4 block cipher (formerly SMS4).

Implementations

impl Sm4

pub fn new(key: &[u8; 16]) -> Self

Construct SM4 from a 128-bit key.

pub fn new_wiping(key: &mut [u8; 16]) -> Self

Construct SM4 and wipe the caller-provided key buffer.

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

Encrypt one 128-bit block.

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

Decrypt one 128-bit block.

Trait Implementations

impl BlockCipher for Sm4

const BLOCK_LEN: usize = 16
