Struct XSalsa20 

pub struct XSalsa20 { /* private fields */ }

XSalsa20 stream cipher with a 24-byte nonce.

A thin wrapper: it derives a subkey with HSalsa20 from the first 16 nonce bytes and runs Salsa20 with the derived key and the remaining 8 nonce bytes.

Implementations

impl XSalsa20

pub fn new(key: &[u8; 32], nonce: &[u8; 24], counter: u64) -> Self

Initialise XSalsa20 with a 256-bit key, a 24-byte nonce, and an initial 64-bit block counter (usually 0).

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

XOR the keystream into data in place (symmetric: encrypt or decrypt). Partial calls are buffered like Salsa20.

Trait Implementations

impl Clone for XSalsa20

fn clone(&self) -> XSalsa20

Returns a duplicate of the value.

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

Performs copy-assignment from source.
