async_io_crypto

A rust library for handling AsyncRead with ciphering / deciphering. It combines aead crate with tokio IO traits

lib.rs:

Provides a wrapper around a AsyncRead

#[tokio::main]

let key = b"my very super super secret key!!";
let plaintext = b"hello world!";

let mut csprng = rand_chacha::ChaCha20Rng::from_entropy();
let cipher: ChaCha20Poly1305 = ChaCha20Poly1305::new(Key::from_slice(key));
let (mut ci_reader, nonce) = CipherRead::new(&plaintext[..], cipher.clone(), &mut csprng);

let mut ciphered = Vec::new();
ci_reader.read_to_end(&mut ciphered).await.unwrap();

let mut deci_reader = DecipherRead::new(&ciphered[..], cipher, nonce.as_slice());
let mut deciphered = Vec::new();
deci_reader.read_to_end(&mut deciphered).await.unwrap();
assert_eq!(deciphered, plaintext);
