asmcrypto.js

What is asmcrypto.js?

asmcrypto.js is a JavaScript library that provides cryptographic algorithms implemented in WebAssembly and JavaScript. It aims to offer high-performance cryptographic operations for web applications.

What are asmcrypto.js's main functionalities?

Hashing

This feature allows you to perform hashing operations. The example demonstrates how to compute the SHA-256 hash of a string.

const asmCrypto = require('asmcrypto.js');
const hash = asmCrypto.SHA256.hex('Hello, World!');
console.log(hash);

Symmetric Encryption

This feature allows you to perform symmetric encryption using algorithms like AES. The example shows how to encrypt a string using AES-CBC.

const asmCrypto = require('asmcrypto.js');
const key = asmCrypto.AES_CBC.generateKey(16);
const encrypted = asmCrypto.AES_CBC.encrypt(asmCrypto.string_to_bytes('Hello, World!'), key);
console.log(encrypted);

Asymmetric Encryption

This feature allows you to perform asymmetric encryption using algorithms like RSA. The example demonstrates how to encrypt a string using RSA.

const asmCrypto = require('asmcrypto.js');
const keyPair = asmCrypto.RSA.generateKey(1024);
const encrypted = asmCrypto.RSA.encrypt(asmCrypto.string_to_bytes('Hello, World!'), keyPair.publicKey);
console.log(encrypted);

Digital Signatures

This feature allows you to create digital signatures. The example shows how to sign a string using RSA.

const asmCrypto = require('asmcrypto.js');
const keyPair = asmCrypto.RSA.generateKey(1024);
const signature = asmCrypto.RSA.sign(asmCrypto.string_to_bytes('Hello, World!'), keyPair.privateKey);
console.log(signature);

Other packages similar to asmcrypto.js

crypto-js

crypto-js is a widely-used library that provides standard and secure cryptographic algorithms implemented in JavaScript. It is known for its ease of use and comprehensive documentation. Compared to asmcrypto.js, crypto-js does not utilize WebAssembly for performance optimization.

node-forge

node-forge is a robust library that offers a wide range of cryptographic operations, including SSL/TLS, PKI, and more. It is highly versatile and suitable for both client-side and server-side applications. Unlike asmcrypto.js, node-forge is purely JavaScript-based and does not leverage WebAssembly.

sjcl

Stanford JavaScript Crypto Library (sjcl) is a compact, fast, and secure cryptographic library. It is designed to be easy to use and includes a variety of cryptographic primitives. While sjcl is efficient, it does not use WebAssembly for performance enhancements like asmcrypto.js.

cd asmcrypto.js/
npm install

Running tests is always a good idea:

npm test

Congratulations! Now you have your asmcrypto.js ready to use ☺

AsmCrypto 2.0

• Moved to TypeScript
• I have no confident knowledge on random generation, so I don't feel right maintaining it. As of 2.0 all custom random generation and seeding code is removed, the underlying browsers and environments have to provide secure random.
