Struct salsa20::SalsaCore

pub struct SalsaCore<R: Unsigned> { /* private fields */ }

The Salsa20 core function.

Implementations

impl<R: Unsigned> SalsaCore<R>

pub fn from_raw_state(state: [u32; 16]) -> Self

Create new Salsa core from raw state.

This method is mainly intended for the scrypt crate. Other users generally should not use this method.
