Open Source Cryptography Software

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

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 small but powerful. The minified version of the library is under 6.4KB compressed, and yet it posts impressive speed results. 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. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified. We believe that SJCL provides the best security which is practically available in Javascript.

User AES-128 bit encryption in counter mode of operation. supports interactive mode of operation and command line mode of operation.

Java library with Cryptographic algorithms. Easy to use Crypto algorithms. Works on Windows, Linux, Android. No external lib dependencies, no useless abstractions, no 'crypto provider'. Elliptic curves was borrowed from BouncyCastle and simplified a lot. Most of EC classes are custom algorithms for certain curves. Can be easily deleted if u dont need them. With couple of classes u can parse and construct those ugly ASN.1 structures, look at RSA and EC key formats for example. No bad dependencies between classes, so u can easily cut off unnecessary code and simply include what u need in your project. Feel free and simple without headache. We are using class Binary as best for us to work with byte arrays. Simple classes for console-like colored apps in GUI-mode. Look also http://demo.sls.team

This project has been migrated to GitHub : https://github.com/vlachenal/anch-framework AnCH framework aims to provide utility classes for some common programming features. Features are implemented to be used as simply as possible. This framework was initially a way to test new C++ specifications (C++11) and to test C++ design patterns and tricks. Only POSIX systems are supported for now. Others could be supported later. (Partial) Doxygen documentation can be found on project home page.

BBSGen is an improved Blum-Blum-Shub pseudorandom number generator. It consists of a C library (libbbsgen) and command-line tool (bbsgen). BBSGen can be used in applications and command-line as secure, unpredictable and strong PRNG.

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

This is a JavaScript library which gives the ability to use cryptographic functionality abstracted of available technologies on the browser side. It executes a cryptographic function with the fastest technology including Java, JavaScript and Flash.

Formerly known as DotNetOpenId, this library brings easy and flexible OpenID, OAuth and InfoCard to the .NET platform. Official web site is at http://www.dotnetopenauth.net/, which includes source code downloads.

This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

JConfigura is a library usable in java environments for sharing configuration parameters between different java applications. Moreover it exculpates developers of aspects like property file reading and securing property files with rsa encryption.

RainDoll aims to be an implementation of a symmetric-encryption utility for desktop users written in C#/.NET and Windows Forms with two goals: security and simplicity. It uses cryptographic standards for security, and has a smart, compact interface.

This is a JavaScript library which gives the ability to use cryptographic functionality abstracted of available technologies on the browser side. It executes a cryptographic function with the fastest technology including Java, JavaScript and Flash.

This project has moved to https://github.com/julesbl/ssp and is now PHP7 complient and works in composer. The objective of these routines is to supply a secure login system to be wrapped round php applications and websites so that developers do not need to write their own. These libraries have been hardened against most web type attacks. Now has internationalisation and multiple languages.

A kind of encryption named "simple stream encrypt". The length of plaintext segment or the length of key is not limited, but must greater than zero. The lengths of every plaintext segment in a process don't require equivalency.

StrongKey CryptoEngine (SKCE) 2.0 is a "crypto Swiss Army knife" server to perform cryptographic functions through web services, while freeing application developers to focus on business functionality.

Tink is a multi-language, cross-platform, open source library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse. Tink is an open-source cryptography library written by cryptographers and security engineers at Google. Tink's secure and simple APIs reduce common pitfalls through user-centered design, careful implementation and code reviews, and extensive testing. Tink helps users without a cryptography background safely implement common cryptographic tasks. At Google, Tink has been deployed in hundreds of products and systems. Cryptography is difficult to get right. With Tink, you can encrypt or sign data with just a few lines of code, with built-in security guarantees to help you avoid pitfalls. Tink adds security protections on top of well known libraries like BoringSSL and Java Cryptography Architecture and shows them right in the interfaces, so auditors and tools can quickly find gaps.

This is a java native wrapper, based on JNA of standard methods to access smart cards (pkcs11, pc/sc, openct, libusb). Goals of this projects are: * interoperability: it can work on any platform where JNA runs: Windows, Linux, Mac (and one day even Android) * modularity: you don't need to include pc/sc support if you only use pkcs11 * ease of integration: it depends only on few required libraries. * ease of use: it exposes a simple java interface (even if you can deal with the JNA classes directly)
