Encrypting Data

This feature allows you to encrypt data using a raw AES keyring. The code sample demonstrates how to create a RawAesKeyringNode and use it to encrypt a plaintext string.

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

const keyName = 'example-key-name';
const keyNamespace = 'example-key-namespace';
const unencryptedMasterKey = Buffer.from('00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff', 'hex');

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

const plaintext = 'Hello, World!';

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

Decrypting Data

This feature allows you to decrypt data that was encrypted using a raw AES keyring. The code sample demonstrates how to create a RawAesKeyringNode and use it to decrypt an encrypted data buffer.

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

const keyName = 'example-key-name';
const keyNamespace = 'example-key-namespace';
const unencryptedMasterKey = Buffer.from('00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff', 'hex');

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

const encryptedData = /* previously encrypted data */;

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