Salsa20 is a stream cipher built on a pseudo-random function based on add-rotate-xor operations — 32-bit addition, bitwise addition and rotation operations.
To install rust-salsa20, add the following to your Cargo.toml:
toml
[dependencies]
rust-salsa20 = "^0.2"
```rust extern crate rustsalsa20; use rustsalsa20::{Salsa20, Key::Key32};
fn main() { let key = Key32([ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 ]); let nonce = [1, 2, 3, 4, 5, 6, 7, 8]; let mut salsa = Salsa20::new(key, nonce, 0); let mut buffer = [0; 10]; salsa.generate(&mut buffer);
assert_eq!(buffer, [45, 134, 38, 166, 142, 36, 28, 146, 116, 157]);
} ```
