Struct rcrypto::ZUCCipher

pub struct ZUCCipher { /* fields omitted */ }

ZUC stream cipher algorithm
GM/T 0001-2012

Implementations

impl ZUCCipher

pub fn new(count: u32, bearer: u8, direction: bool, ck: [u8; 16]) -> ZUCCipher

bearer: only the lowest 5 bits are valid

pub fn from_slice(
    count: u32,
    bearer: u8,
    direction: bool,
    ck: &[u8]
) -> Result<ZUCCipher, CryptoError>

bearer: only the lowest 5 bits are valid

pub fn reset(&mut self)

this will reset to the initialization status

Trait Implementations

impl Cipher for ZUCCipher

type Output = usize

fn block_size(&self) -> Option<usize>

The cryptography algorithm used data block size(in bytes) for plaintext, None means that there is no requirement for the data block size.

fn encrypt(
    &self,
    dst: &mut Vec<u8>,
    plaintext_block: &[u8]
) -> Result<usize, CryptoError>

To encrypt the data_block and output the encrypted data dst, the length in bytes of the encrypted data will return if encrypt success, otherwise CryptoError returned.

fn decrypt(
    &self,
    dst: &mut Vec<u8>,
    cipher_block: &[u8]
) -> Result<usize, CryptoError>

To decrypt the cipher_block and output the decrypted data dst, the length in bytes of the decrypted data will return if decrypt success, other CryptoError returned.

impl Clone for ZUCCipher

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
