# `tokio_chacha20`
ChaCha20 and Poly1305 primitives (primitives are not AEAD).
## How to use
Async:
```rust
let config = create_random_config();
let (client, server) = tokio::io::duplex(1024);
let (r, w) = tokio::io::split(client);
let mut client = WholeStream::from_key_halves(*config.key(), r, w);
let (r, w) = tokio::io::split(server);
let mut server = WholeStream::from_key_halves(*config.key(), r, w);
let data = b"Hello, world!";
let mut buf = [0u8; 1024];
client.write_all(data).await.unwrap();
server.read_exact(&mut buf[..data.len()]).await.unwrap();
```
Sync:
```rust
let config = create_random_config();
let msg = b"Hello world!";
let mut en = EncryptCursor::new(*config.key());
let mut de = DecryptCursor::new(*config.key());
let mut buf = [0; 1024];
let (_, n) = en.encrypt(msg, &mut buf).unwrap();
let i = de.decrypt(&mut buf[..n]).unwrap();
let i = i.unwrap();
assert_eq!(&buf[i..n], &msg[..]);
```
