Cryptographic Hashing Libraries

Cryptographic hashing libraries in JavaScript provide functions to generate hash values from data, which are essential for tasks like data integrity verification, password hashing, and digital signatures. These libraries implement various hashing algorithms, such as MD5, SHA-1, and SHA-256, to produce fixed-size hash values that uniquely represent the input data. They are widely used in web development for secure data handling, encryption, and authentication processes. crypto-js is a comprehensive library offering a wide range of cryptographic algorithms, including AES, SHA, and HMAC, making it suitable for various encryption and hashing tasks. hash-sum is a lightweight library focused on generating small, fast, and unique hash values for objects, primarily used for caching and memoization. md5 is a simple library dedicated to generating MD5 hash values, which are commonly used for checksums and basic data integrity verification, but it is not recommended for cryptographic security due to vulnerabilities.

Similar Npm Packages to md5

md5 is a widely used hashing library in the JavaScript ecosystem that allows developers to generate MD5 hashes of strings. MD5, which stands for Message-Digest Algorithm 5, produces a 128-bit hash value, typically represented as a 32-character hexadecimal number. While MD5 is popular for checksums and data integrity verification, it is not recommended for security-sensitive applications due to its vulnerabilities to collision attacks. Here are some alternatives that provide stronger hashing mechanisms:

  • bcrypt is a password hashing library designed to securely hash passwords. It incorporates a salt to protect against rainbow table attacks and allows for adjustable work factors, making it more resistant to brute-force attacks. Bcrypt is widely regarded as a secure choice for password storage and is recommended for applications that require strong password protection.
  • crypto-js is a comprehensive library that provides various cryptographic algorithms, including hashing functions like MD5, SHA-1, and SHA-256. It is a versatile library that can be used for both hashing and encryption, making it suitable for applications that require a broader range of cryptographic functionalities. If you need multiple hashing algorithms or encryption capabilities, crypto-js is an excellent choice.
  • sha1 is a hashing library that implements the SHA-1 algorithm. While SHA-1 is more secure than MD5, it is also considered weak against collision attacks and is not recommended for security-critical applications. However, it can still be useful for non-security-related hashing tasks where a stronger hash than MD5 is needed.
  • sha256 is a library that implements the SHA-256 hashing algorithm, which is part of the SHA-2 family. SHA-256 is widely regarded as secure and is commonly used in various security applications and protocols, including SSL/TLS and blockchain technologies.

README for crypto-js

crypto-js

JavaScript library of crypto standards.

Discontinued

Active development of CryptoJS has been discontinued. This library is no longer maintained.

Nowadays, NodeJS and modern browsers have a native Crypto module. The latest version of CryptoJS already uses the native Crypto module for random number generation, since Math.random() is not crypto-safe. Further development of CryptoJS would result in it only being a wrapper of native Crypto. Therefore, development and maintenance has been discontinued, it is time to go for the native crypto module.

Node.js (Install)

Requirements:

  • Node.js
  • npm (Node.js package manager)
npm install crypto-js

Usage

ES6 import for typical API call signing use case:

import sha256 from 'crypto-js/sha256';
import hmacSHA512 from 'crypto-js/hmac-sha512';
import Base64 from 'crypto-js/enc-base64';

const message, nonce, path, privateKey; // ...
const hashDigest = sha256(nonce + message);
const hmacDigest = Base64.stringify(hmacSHA512(path + hashDigest, privateKey));

Modular include:

var AES = require("crypto-js/aes");
var SHA256 = require("crypto-js/sha256");
...
console.log(SHA256("Message"));

Including all libraries, for access to extra methods:

var CryptoJS = require("crypto-js");
console.log(CryptoJS.HmacSHA1("Message", "Key"));

Client (browser)

Requirements:

  • Node.js

Modular include:

require.config({
    packages: [
        {
            name: 'crypto-js',
            location: 'path-to/bower_components/crypto-js',
            main: 'index'
        }
    ]
});

require(["crypto-js/aes", "crypto-js/sha256"], function (AES, SHA256) {
    console.log(SHA256("Message"));
});

Including all libraries, for access to extra methods:

// Above-mentioned will work or use this simple form
require.config({
    paths: {
        'crypto-js': 'path-to/bower_components/crypto-js/crypto-js'
    }
});

require(["crypto-js"], function (CryptoJS) {
    console.log(CryptoJS.HmacSHA1("Message", "Key"));
});

Usage without RequireJS

<script type="text/javascript" src="path-to/bower_components/crypto-js/crypto-js.js"></script>
<script type="text/javascript">
    var encrypted = CryptoJS.AES(...);
    var encrypted = CryptoJS.SHA256(...);
</script>

AES Encryption

Plain text encryption

var CryptoJS = require("crypto-js");

// Encrypt
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();

// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(CryptoJS.enc.Utf8);

console.log(originalText); // 'my message'

Object encryption

var CryptoJS = require("crypto-js");

var data = [{id: 1}, {id: 2}]

// Encrypt
var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'secret key 123').toString();

// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));

Release notes

4.2.0

Change default hash algorithm and iteration's for PBKDF2 to prevent weak security by using the default configuration.

Custom KDF Hasher

Blowfish support

4.1.1

Fix module order in bundled release.

Include the browser field in the released package.json.

4.1.0

Added url safe variant of base64 encoding. 357

Avoid webpack to add crypto-browser package. 364

4.0.0

This is an update including breaking changes for some environments.

In this version Math.random() has been replaced by the random methods of the native crypto module.

For this reason CryptoJS might not run in some JavaScript environments without native crypto module. Such as IE 10 or before or React Native.

3.3.0

Rollback, 3.3.0 is the same as 3.1.9-1.

The move of using native secure crypto module will be shifted to a new 4.x.x version. As it is a breaking change the impact is too big for a minor release.

3.2.1

The usage of the native crypto module has been fixed. The import and access of the native crypto module has been improved.

3.2.0

In this version Math.random() has been replaced by the random methods of the native crypto module.

For this reason CryptoJS might does not run in some JavaScript environments without native crypto module. Such as IE 10 or before.

If it's absolute required to run CryptoJS in such an environment, stay with 3.1.x version. Encrypting and decrypting stays compatible. But keep in mind 3.1.x versions still use Math.random() which is cryptographically not secure, as it's not random enough.

This version came along with CRITICAL BUG.

DO NOT USE THIS VERSION! Please, go for a newer version!

3.1.x

The 3.1.x are based on the original CryptoJS, wrapped in CommonJS modules.
