Aes256GcmEncryption 0.86.6 API

All Implemented Interfaces:

org.signal.libsignal.internal.NativeHandleGuard.Owner
```
public class Aes256GcmEncryption
extends NativeHandleGuard.SimpleOwner
                    
```
Implements the AES-256-GCM authenticated stream cipher with a 12-byte nonce.
This API exposes the streaming nature of AES-GCM to allow encrypting data without having it resident in memory all at once. You must call computeTag when the encryption is complete to produce the authentication tag for the ciphertext, and then make sure the tag makes it to the decrypter.

Aes256GcmEncryption(Array<byte> key, Array<byte> nonce, Array<byte> associatedData)
```
    Initializes the cipher with the given inputs.
- Method Detail
  - encrypt
```
 void encrypt(Array<byte> plaintext, int offset, int length)
```
    Encrypts plaintext in place and advances the state of the cipher.
    Bytes outside the designated offset/length are unchanged.
    Don't forget to call computeTag when encryption is complete.
  - encrypt
```
 void encrypt(Array<byte> plaintext)
```
    Encrypts plaintext in place and advances the state of the cipher.
    Don't forget to call computeTag when encryption is complete.
  - computeTag
```
 Array<byte> computeTag()
```
    Produces an authentication tag for the plaintext that has been processed.
    After calling computeTag, this object may not be used anymore.
