SwCrypt - RSA public/private key generation, RSA, AES encryption/decryption, RSA sign/verify in Swift with CommonCrypto in iOS and OS X

•    Swift

---

SwCrypt uses dlopen and dlsym to load the CommonCrypto's functions, because not all of them are available in public header files. You have to check the availability before using them. Just copy SwCrypt.swift to your project or use the Carthage dependency manager.

SSH.NET - SSH.NET is a Secure Shell (SSH) library for .NET, optimized for parallelism.

•    CSharp

---

SSH.NET is a Secure Shell (SSH-2) library for .NET, optimized for parallelism.This project was inspired by Sharp.SSH library which was ported from java and it seems like was not supported for quite some time. This library is a complete rewrite, without any third party dependencies, using parallelism to achieve the best performance possible.

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.

SoftEther VPN - Cross-platform Multi-protocol VPN Program

•    C

---

SoftEther VPN is a ?Cross-platform Multi-protocol VPN Program. It supports SSL-VPN protocol to penetrate any kinds of firewalls. Ultra-optimized SSL-VPN Protocol of SoftEther VPN has very fast throughput, low latency and firewall resistance. Virtualization of Ethernet devices is the key of the SoftEther VPN architecture. It virtualizes Ethernet devices in order to realize a flexible virtual private network for both remote-access VPN and site-to-site VPN.

rsatool - rsatool can be used to calculate RSA and RSA-CRT parameters

•    Python

---

rsatool calculates RSA (p, q, n, d, e) and RSA-CRT (dP, dQ, qInv) parameters given either two primes (p, q) or modulus and private exponent (n, d). Resulting parameters are displayed and can optionally be written as an OpenSSL compatible DER or PEM encoded RSA private key.

jsencrypt - A Javascript library to perform OpenSSL RSA Encryption, Decryption, and Key Generation.

•    Javascript

---

When browsing the internet looking for a good solution to RSA Javascript encryption, there is a whole slew of libraries that basically take the fantastic work done by Tom Wu @ http://www-cs-students.stanford.edu/~tjw/jsbn/ and then modify that code to do what they want. What I couldn't find, however, was a simple wrapper around this library that basically uses the library practically untouched, but adds a wrapper to provide parsing of actual Private and Public key-pairs generated with OpenSSL.
