Struct Cbc

pub struct Cbc<B: BlockCipher + Zeroize + ZeroizeOnDrop> { /* private fields */ }

CBC mode implementation

Implementations

impl<B: BlockCipher + CipherAlgorithm + Zeroize + ZeroizeOnDrop> Cbc<B>

pub fn new<const N: usize>(cipher: B, iv: &Nonce<N>) -> Result<Self>

where Nonce<N>: CbcCompatible,

Creates a new CBC mode instance with the given cipher and IV

The IV (nonce) must be the same size as the block size of the cipher.

pub fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>>

Encrypts a message using CBC mode

The plaintext must be a multiple of the block size. For plaintext that is not a multiple of the block size, padding must be applied before calling this function.

pub fn decrypt(&self, ciphertext: &[u8]) -> Result<Vec<u8>>

Decrypts a message using CBC mode

The ciphertext must be a multiple of the block size.

Trait Implementations

impl<B: Clone + BlockCipher + Zeroize + ZeroizeOnDrop> Clone for Cbc<B>

fn clone(&self) -> Cbc<B>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<B: BlockCipher + Zeroize + ZeroizeOnDrop> Drop for Cbc<B>

fn drop(&mut self)

Executes the destructor for this type.

impl<B> Zeroize for Cbc<B>

where B: Zeroize + BlockCipher + ZeroizeOnDrop,

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
