Aes256GcmSiv 0.86.6 API

All Implemented Interfaces:

org.signal.libsignal.internal.NativeHandleGuard.Owner
```
public class Aes256GcmSiv
extends NativeHandleGuard.SimpleOwner
                    
```
Implements the AES-256-GCM-SIV authenticated stream cipher with a 12-byte nonce.
AES-GCM-SIV is a multi-pass algorithm (to generate the "synthetic initialization vector"), so this API does not expose a streaming form.

```
- Method Detail
  - encrypt
```
 Array<byte> encrypt(Array<byte> plaintext, Array<byte> nonce, Array<byte> associated_data)
```
    Encrypts the given plaintext using the given nonce, and authenticating the ciphertext and given associated data.
    The associated data is not included in the ciphertext; instead, it's expected to match between the encrypter and decrypter. If you don't need any extra data, pass an empty array.
    
    Returns:
    
    The encrypted data, including an appended 16-byte authentication tag.
  - decrypt
```
 Array<byte> decrypt(Array<byte> ciphertext, Array<byte> nonce, Array<byte> associated_data)
```
    Decrypts the given ciphertext using the given nonce, and authenticating the ciphertext and given associated data.
    The associated data is not included in the ciphertext; instead, it's expected to match between the encrypter and decrypter.
    
    Returns:
    
    The decrypted data
