@aws-crypto/raw-keyring

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());
})();

Other packages similar to @aws-crypto/raw-keyring

crypto

The 'crypto' module in Node.js provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. Unlike @aws-crypto/raw-keyring, it does not provide a high-level abstraction for key management and encryption/decryption operations.

node-forge

Node-forge is a JavaScript library that provides a native implementation of TLS (and various other cryptographic tools) in JavaScript. It offers more granular control over cryptographic operations compared to @aws-crypto/raw-keyring, but does not integrate directly with AWS services.

sjcl

Stanford Javascript Crypto Library (SJCL) is a library for cryptography in JavaScript. It is designed to be secure, fast, and easy to use. SJCL provides a variety of cryptographic primitives but does not offer the same level of integration with AWS services as @aws-crypto/raw-keyring.
