What is @aws-crypto/raw-keyring?

@aws-crypto/raw-keyring is a package provided by AWS that allows developers to use raw keyrings for cryptographic operations. This package is part of the AWS Encryption SDK and is used to encrypt and decrypt data using raw cryptographic keys.

What are @aws-crypto/raw-keyring's main functionalities?

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());
})();
