## \[0.4.0]

- Add a `Aead` trait and expose a common API through the `Aes256Gcm` and `XChaCha20Poly1305` types.

To migrate from the previous `AES-GCM/ChaCha` implementations:

```rust
AES_256_GCM::encrypt(&key, &iv, &associated_data, &plaintext, &mut ciphertext, &mut tag)?;
// |
// v
Aes256Gcm::encrypt(&key, &iv, &associated_data, &plaintext, &mut ciphertext, &mut tag)?;
```

```rust
AES_256_GCM::decrypt(&key, &iv, &associated_data, &tag, &ciphertext, &mut plaintext)?;
// |
// v
Aes256Gcm::decrypt(&key, &nonce, &associated_data, &tag, &ciphertext, &mut plaintext)?;
```

```rust
xchacha20poly1305::encrypt(&mut ciphertext, &tag, &plaintext, &key, &nonce, &associated_data)?;
// |
// v
XChaCha20Poly1305::encrypt(&key, &nonce, &associated_data, &plaintext, &mut ciphertext, &mut tag)?;
```

```rust
xchacha20poly1305::decrypt(&mut plaintext, &ciphertext, &key, &tag, &nonce, &associated_data)?;
// |
// v
XChaCha20Poly1305::decrypt(&key, &nonce, &associated_data, &tag, &ciphertext, &mut plaintext)?;
```

- Normalization of the parameters for the encryption and decryption functions.

- Parameter lists are as follows:

```rust
encrypt(
    key,
    nonce,
    associated_data,
    plaintext,
    ciphertext,
    tag
);

decrypt(
    key,
    nonce,
    associated_data,
    plaintext,
    ciphertext,
    tag
);

try_encrypt(
    key,
    nonce,
    associated_data,
    plaintext,
    ciphertext,
    tag
);

try_decrypt(
    key,
    nonce,
    associated_data,
    plaintext,
    ciphertext,
    tag
);
```

Changed the BufferSize error to include a name in the error message.

```rust
/// Produces an error message containing the following: 
/// $name buffer needs $needs bytes, but it only has $has

Error::BufferSize(
    name,
    needs,
    has
);
```
