Open Source Encryption Algorithms

Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.

QPass is easy to use, open source password manager application with built-in password generator. You can store in it's database such data as passwords and logins which will be encrypted using AES-256 with PBKDF2(number of iterations set by user). Each entry can include additional information about entry such as name, url adress and description.

The AWS Encryption SDK is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts.

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding. ShredBitz is a very powerful tool.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

TinyCrypt is a simple secure program for encrypting files. The core encryption code is only 76 lines of C code, based on the well known ARC4-D(768) algorithm.

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

This software provides a mean for users to encrypt and decrypt data in the form of text and images. The program follows a basic encryption algorithm that relies on mathematical properties of matrices, such as row operations, matrix multiplication, and invertible matrices . This program works by allowing the user to input a key in the form of a matrix, on which the program bases the encryption. The program then performs the encryption. The software only works in the scope of text files with a maximum of 150 characters, and image files with a maximum size of 128 x 128.

A command-line to help encipher and decipher your password based on a simple algorithm. Java version provides GUI.

AES_in_CBC_mode_for_microcontrollers is an open-source code that enables you to easily integrate the AES encryption algorithm in CBC mode to your project. Based on the work of https://github.com/zhouyangchao/AES GitHub Page: https://github.com/Northstrix/AES_in_CBC_mode_for_microcontrollers

Abdal AES Encryption is a security tool for encrypting messages developed by the Abdal team. This tool uses AES encryption and has high power. AES stands for Advanced Encryption Standard, which was developed in 2001 by the US National Institute of Technology and Standards. The advanced encryption standard is accepted by the US government and is now used worldwide. This encryption algorithm replaces the Data Encryption Standard (DES) published in 1977.

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

A library written in Visual C# for encrypting a text message into an image file, and decrypting an image file to get the text message using Rijndael Algorithm, RSA Algorithm, and LSB Substitution Algorithm.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

This Java project is an attempt to crack the key in a DES encryption algorithm. The plaintext and the cyphertext are known. The purpose is to crack the 64-bit key with 3 rounds instead of 16. This project checks all 2^64 possible keys. Therefore, it takes a long time to find the correct key.
