## Encrypt
|
|
|
|
```rust
|
|
// IMPORTANT! key and nonce SHOULD generate by random
|
|
let mut key = [0u8; 32];
|
|
let mut nonce = [0; 12];
|
|
|
|
let mut encryptor = Aes256GcmStreamEncryptor::new(key.clone(), &nonce);
|
|
|
|
let mut ciphertext = vec![];
|
|
ciphertext.extend_from_slice(&encryptor.update(b"Hello "));
|
|
ciphertext.extend_from_slice(&encryptor.update(b" World"));
|
|
ciphertext.extend_from_slice(&encryptor.update(b"!"));
|
|
let (last_block, tag) = encryptor.finalize();
|
|
ciphertext.extend_from_slice(&last_block);
|
|
ciphertext.extend_from_slice(&tag);
|
|
|
|
println!("Ciphertext: {}", hex::encode(&ciphertext));
|
|
```
