JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

JavaScript Cryptography Toolkit

This library is an object oriented cryptography toolkit that implements several fundamental cryptographic algorithms including TWOFISH, SERPENT, RIJNDAEL, RSA with key-generation and SHA(SHA-1,224,256,384,512) for JavaScript. This library works in ActionScript as well. The unique feature of this library is asynchronous processing. A heavyweight process such as 4096bit RSA key generation will be done asynchronously so that this library does not cause problems such as freezing browsers, "slow-downing" warning dialogs, etc.

• asynchronous RSA key generation

A JavaScript Cryptography Library

This library is an object oriented cryptography library that implements several fundamental cryptographic algorithms including AES, SHA-1, HMAC, BASE64, RSA, ECC and IBE for JavaScript. This library works in ActionScript as well.

Can anyone point me to actual security analysis on any of these crypto libraries? HOW SECURE are they? Which ones have been cracked? How secure are these libraries to things like cache timing attacks? Which are considered the best, and why? How do they compare to the new W3C WebCrypto API? I think any libraries that haven't passed strong security testing should be relisted on this page under a DO NOT USE list.

I'm actually trying to move away from SJCL because the maintainer has abandoned the project and it doesn't play well with CommonJS require statements under some architectures. I looked for security analysis of SJCL and I couldn't find any, other than an offhand mention of a known vulnerability to cache timing attacks. Why do people trust crypto-js? Because the authors at Google would never do evil? They don't even host the code anymore, and the docs are minimal to say the least.

@Tectract Sorry but there is no such info you request. The SJCL lib is one of the most used with crypto-js and JSEncrypt.
Take a look of a new list I did based in this one, but added some data about the libraries that will help you to evaluate them: JavaScript Crypto Libraries.

I want to share with CryptoBench.js - a benchmark testbed for some crypto libraries: asmcrypto.js, crypto-js, forge, libsodium.js, js-nacl, sjcl and tweetnacl.js.

How about jsrsasign?

Can i get a library which implement RSA. Has a method that get secret and generate keypair and it simply implement encryption, decryption, signing and verifying

Hi guys
Could you please advice some library to generate ECDSA keypair in browser which could be suitable for using with web3 (ethereum) on backend? I've tried with jsrasign but failed - web3 was not satisfied by results.

The recently released PJCL may be the only JS crypto library that provides DSA and comes with sample code for implementing cryptographic authentication in web apps as explained in this blog post.

@fcorella
PJCL looks interesting, but why isn't the code hosted on Github? Why isn't there a commonly used license? Where is the issue tracking? Why doesn't the example have a package.json so I can install the dependencies? I think a lot of people might be turned off by those things.

Is there any means by which while using RSA I can encrypt data with Private key (or assume I receive data which is encrypted using private key) and I decrypt using Public key.
Any help would be appreciated

Encryption for data at-rest made practical

VESvault: Encrypt Evertyhing without fear of losing the Key.

• Share encrypted data with your friends and colleagues.
• Securely exchange temporary keys with new users.
• Viral Encrypted Security (VES): Recover your data through a viral network of friends in case of the encryption key loss.

Cloud based end-to-end encryption API

VES.host: VESvault API integration center.
libVES.c: C library and command line utility.
libVES.js: JS library

Some link is wrong. Please check it again

Anyone uses https://github.com/safebash/opencrypto?
Looks good, but I get an DOMexception with increased data to encrypt. Works fine with https://github.com/encryb/simplecrypto, but here key export and some more features are missing?

If you're not big into closure, but want to use google's closure crypt library, you can use this wrapper around it. It supports typescript and works great on NodeJS. You don't need to know a thing about closure.

https://www.npmjs.com/package/@google-closure-library/goog.crypt

The easiest ASN.1 library to work with by far: https://github.com/indutny/asn1.js/

Most of these or even all of them are npm packages. I would like to know what are my options for using as a single js file to include it in a simple lightweight web page, so I could just copy it and don't bother with npm, yarn, whatever.

help me please i want to crypt data in arduino uno (AES) and decrypt data in node js (AES) ...give me a solution

Checkout my project Cypher. It appends to Object, Object.prototype and String.prototype pretty fast and secure methods for synchronous encryption and decryption. I have also built a method that gives you unique randomised symmetric keys. If you'd like to see it running and do some testing, go here (use the testing.js file for testing).

We're using http://www-cs-students.stanford.edu/~tjw/jsbn/ and getting window.crypto.random is not a function error at line 39 in rng.js file in IOS webviewcontroller. We're using Xcode 11.3 for native apps. Can you please look into it? It's working fine for previous version of Xcode and other browsers as well.

Also EthAir Balloons. A very useful strictly typed ORM library for Ethereum blockchain.

It has disappeared?

Is there a lib to encrypt/decrypt binary with ethereum wallet ecdsa pubkey and private key?

I don't think this is standardized yet. Check out https://ethereum-magicians.org/t/eip-1024-cross-client-encrypt-decrypt/505 as well.

FYI, we also just published Skiff Crypto, which is open-source, has asymmetric/symmetric crypto for Node.JS + browser runtime. It also has object versioning capabilities. Repo link - https://github.com/skiff-org/skiff-apps/tree/main/libs/skiff-crypto.
