ChaCha Context

Implementations

impl ChaCha20

pub fn new(key: &[u8], nonce: &[u8]) -> ChaCha20

Create a new ChaCha20 context.

• The key must be 16 or 32 bytes
• The nonce must be 8 or 12 bytes

pub fn new_xchacha20(key: &[u8], nonce: &[u8]) -> ChaCha20

Create a new XChaCha20 context.

Key must be 32 bytes and the nonce 24 bytes.

impl ChaCha20

pub fn process_mut(&mut self, data: &mut [u8])

Process the input in place through the cipher xoring

pub fn process(&mut self, input: &[u8], output: &mut [u8])

Process the input through the cipher, xoring the byte one-by-one

the output need to be the same size as the input otherwise this function will panic.

Trait Implementations

impl Clone for ChaCha20

fn clone(&self) -> ChaCha20

Returns a copy of the value.

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