sjcl - Stanford Javascript Crypto Library

•    Javascript

---

The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes.

object-hash - Generate hashes from javascript objects in node and the browser.

•    Javascript

---

Generate hashes from objects and values in node and the browser. Uses node.js crypto module for hashing. Supports SHA1 and many others (depending on the platform) as well as custom streams (e.g. CRC32). Starting with version 1.1.8 (released April 2017), new versions will consider the exact returned hash part of the API contract, i.e. changes that will affect hash values will be considered semver-major. Previous versions may violate that expectation.

Botan - Crypto library for C++

•    C++

---

Botan (Japanese for peony) is a cryptography library written in C++11. Botan's goal is to be the best option for cryptography in new C++ code by offering the tools necessary to implement a range of practical systems, such as TLS/DTLS, PKIX certificate handling, PKCS#11 and TPM hardware support, password hashing, and post quantum crypto schemes. In addition to the C++, botan has a C89 API specifically designed to be easy to call from other languages. A Python binding using ctypes is included, and several other language bindings are available.

Jasypt - Java Simplified Encryption

•    Java

---

Jasypt is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works. It provides unidirectional (digest) and bidirectional encryption techniques. It could encrypt text, byte arrays, objects, files etc. It could be integrated with Spring, Apache wicket.

featherduster - An automated, modular cryptanalysis tool; i.e., a Weapon of Math Destruction

•    Python

---

FeatherDuster is a tool written by Daniel "unicornfurnace" Crowley of NCC Group for breaking crypto which tries to make the process of identifying and exploiting weak cryptosystems as easy as possible. Cryptanalib is the moving parts behind FeatherDuster, and can be used independently of FeatherDuster. Why "FeatherDuster"? There's an in-joke amongst some crypto folk where using crypto poorly, or to solve a problem that crypto isn't meant to solve is called "sprinkling magical crypto fairy dust on it". FeatherDuster is for cleaning up magical crypto fairy dust.

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.
