#### Usage

```rust

let key = hex::decode("85d6be7857556d337f4452fe42d506a80103808afb0db2fd4abff6af4149f51b").unwrap();

let key = key.as_slice();

let nonce = [0u8; 12];

let mut message = *b"Cryptographic Forum Research Group";

let cipher = ChaCha20Poly1305::new(key.try_into().unwrap(), nonce);

let mut buffer = [0u8; 50];

cipher.encrypt(message.as_mut_slice(), None, buffer.as_mut_slice());

```
