Struct nettle::mode::Cbc

pub struct Cbc<C: Cipher> { /* fields omitted */ }

Cipher block chaining mode.

Implementations

impl<C: Cipher> Cbc<C>

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

Create a new encrypting CBC instance with key.

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

Create a new decrypting CBC instance with key.

Trait Implementations

impl<C: Cipher> Mode for Cbc<C>

fn block_size(&self) -> usize

Block size of the underlying cipher in bytes.

fn encrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>

Encrypt a single block src using the initialization vector iv to a ciphertext block dst. Both iv and dstare updated. The bufferiv, dstandsrc` are expected to be at least as large as the block size of the underlying cipher.

fn decrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>

Decrypt a single ciphertext block src using the initialization vector iv to a plaintext block dst. Both iv and dstare updated. The bufferiv, dstandsrc` are expected to be at least as large as the block size of the underlying cipher.
