Encrypting Data

This code sample demonstrates how to use the @aws-crypto/raw-aes-keyring-node package to encrypt data. It creates a RawAesKeyringNode with a specified key and uses it to encrypt a plaintext message.

const { RawAesKeyringNode, encrypt } = require('@aws-crypto/client-node');
const { KeyringNode } = require('@aws-crypto/raw-aes-keyring-node');

const keyName = 'example-key';
const keyNamespace = 'example-namespace';
const unencryptedMasterKey = Buffer.from('00112233445566778899aabbccddeeff', 'hex');

const keyring = new RawAesKeyringNode({
  keyName,
  keyNamespace,
  unencryptedMasterKey
});

const plaintext = Buffer.from('Hello, world!');

(async () => {
  const { result } = await encrypt(keyring, plaintext);
  console.log(result); // Encrypted data
})();

Decrypting Data

This code sample demonstrates how to use the @aws-crypto/raw-aes-keyring-node package to decrypt data. It creates a RawAesKeyringNode with a specified key and uses it to decrypt an encrypted message.

const { RawAesKeyringNode, decrypt } = require('@aws-crypto/client-node');
const { KeyringNode } = require('@aws-crypto/raw-aes-keyring-node');

const keyName = 'example-key';
const keyNamespace = 'example-namespace';
const unencryptedMasterKey = Buffer.from('00112233445566778899aabbccddeeff', 'hex');

const keyring = new RawAesKeyringNode({
  keyName,
  keyNamespace,
  unencryptedMasterKey
});

const encryptedData = Buffer.from('...'); // Replace with your encrypted data

(async () => {
  const { plaintext } = await decrypt(keyring, encryptedData);
  console.log(plaintext.toString()); // Decrypted data
})();
