OpenPGP.js - OpenPGP implementation for JavaScript

•    Javascript

---

OpenPGP.js is a JavaScript implementation of the OpenPGP protocol. It aims to provide an Open Source OpenPGP library in JavaScript so it can be used on virtually every device. This does not require gpg on their machines in order to use the library. The idea is to implement all the needed OpenPGP functionality in a JavaScript library that can be reused in other projects that provide browser extensions or server applications. It should allow you to sign, encrypt, decrypt, and verify any kind of text - in particular e-mails - as well as managing keys.

•    Javascript

---

This library developed and tested primary for Node.js, but it still can work in browsers with browserify. You can specify some options by second/third constructor argument, or over key.setOptions() method.

rustls - A modern TLS library in Rust

•    Rust

---

Rustls is a modern TLS library written in Rust. It's pronounced 'rustles'. It uses ring for cryptography and libwebpki for certificate verification. It aims to provide a good level of cryptographic security, requires no configuration to achieve that security, and provides no unsafe features or obsolete cryptography.

Heimdall - Heimdall is a wrapper around the Security framework for simple encryption/decryption operations

•    Swift

---

In Norse mythology, Heimdall is the gatekeeper of Bifröst, the rainbow road connecting Midgard, realm of the humans, to Asgard, the realm of gods. In iOS, Heimdall serves as a gatekeeper between Security framework and the UI, offering a nice wrapper around the C APIs for encrypting, decrypting, signing and verifying messages.

RSA-and-LLL-attacks - attacking RSA via lattice reductions (LLL)

•    TeX

---

This repo host implementations and explanations of different RSA attacks using lattice reduction techniques (in particular LLL). First, we'll see how Coppersmith found out that you could use lattice reduction techniques to attack a relaxed model of RSA (we know parts of the message, or we know parts of one of the prime, ...). And how Howgrave-Graham reformulated his attack.

keypair - Generate a RSA PEM key pair from pure JS

•    Javascript

---

Performance greatly depends on the bit size of the generated private key. With 1024 bits you get a key in 0.5s-2s, with 2048 bits it takes 8s-20s, on the same machine. As this will block the event loop while generating the key, make sure that's ok or to spawn a child process or run it inside a webworker.Get an RSA PEM key pair.

hybrid-rsa-stream - encrypt symmetric keys using asymmetric rsa keys

•    Javascript

---

This hybrid approach is necessary because encrypting more than n/8-11 bytes with an asymmetric key is considered insecure, so the asymmetric key encrypts a generated key for a symmetric block cipher.Return a through stream enc that takes cleartext as input and produces ciphertext as output encrypted with a public key buffer or string publicKey in PEM or ssh-style format.

rsa-stream - encrypt/decrypt rsa with streams

•    Javascript

---

This module is a bit silly unless you are using it as a wrapper because you shouldn't encrypt too many bytes with asymmetric crypto. Instead, encrypt a key for a symmetric cipher in a short header and then switch to symmetric crypto for the payload.You should probably be using hybrid-rsa-stream instead.
