Open Source Encryption Algorithms

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

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.

mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).

Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store & categorize your passwords, which are encrypted using the blowfish algorithm. It can launch applications using the host names, user names, and passwords you supply.

Rinecrypt uses the Gladman implentation of the AES algorithm Rijndael and a SHA256 hash among other things, to encrypt/decrypt a file with a user supplied passsword.

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.

A simple working implementation of 64-bit DES encryption/decryption alogrithm in C++. Could act as guide to undestanding the algorithm. Its buggy so help me out :-)

ALIMP (A LIttle More Privacy) is a .NET C# software enabling users to easily cypher and de-cypher files on their computer using common algorithm (DES, 3DES, AES, ...) that are shipped with the .NET Frawemork.

Alkindus is an automated solver for short monoalphabetic substitution ciphers without word divisions.

This is an experimental program that encrypt/decrypt/divide/join files. This program uses a new algorithm made by me, this algorithm is experimental and I working on it, every day this algoritm will be better.

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

This its a simple project of the RSA algorithm. The purpose of this project isn't to develop an impressive program, it's an easy understand of the algorithm and the C programing.

We developed a classic solution that reflects the very nature of quantum mechanics in whole, ultimately demonstrating the raw power of numbers. We developed a truly irreversible one way algorithm which, when applied to information, both encrypts and decrypts it. That is to say that the algorithm which encrypts the information works in the same direction as the algorithm that decrypts it. This in itself is the very nature of quantum mechanics - "forward only". Through a quantum-entanglement-like operation, we created very robust encryption methodology which will secure information for some time to come through sheer numbers and flexibility. With 2^65536 possible keys a brute force attack on a key is simply infeasible. The full version, due to release March 11, 2013 will allow password protection which helps protect your information by forcing the impostor to not only produce the 65536 bit key, but have your password as well and allows for individual passwords for individual files.

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

CryptoServer is the daemon for handling Sign-Verify, Encryption-Dencryption, Envelop-Openenvelop based on OpenSSL including the SEED symmetric algorithm (Korean Standard Symmetric Algorithm). It's interface is just tcp/ip socket and very easy to handle

In distributed cryptosystem a secret key is distributed among the participants of the system, in the way that only a group of some authorized users can perform any actions related to the secret key. A secret key is used to encrypt a session key, create a digital signature and to certify public keys. The system uses symetric encryption algorithm with a session key to encrypt messages. Shoup’s threshold signature scheme has been used for cooperative signing and also for cooperative decryption.

A library written in Java and C# for crypt,encrypt and generate key pairs using the ElGamal algorithm.

My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's less than the block size. I hold no guarantee of the security of this algorithm, USE AT YOUR OWN RISK. I have had no 3rd party analysis done on the algorithm to date, but research is welcome, and a challenge is even provided in CHALLENGE.txt.

Fileprivacy is a small tool which easily encrypts and decrypts files with common algorithms like AES, Blowfish, Triple DES and RSA. You can either use passwords or keyfiles. Since Fileprivacy is coded in Java it should run on all popular operating systems. #######BETA 2####### Bugfix - Beta 1 stopped working if filename was too short or long - added .exe file ####### NOTE ####### This is an early beta implying there are some issues left. The Keygenerator stops working if you change the algorithm after setting the keylength. It has to be restarted for further use. Because there are no start scripts, yet, you have to start Fileprivacy from console by typing: java -jar Fileprivacy-1.0_<version>.jar ####### ALSO NOTE ####### The author of this software is not responsible for the safety of your data. There is no guarantee that one or more of the implemented algorithms cannot be compromised.

JSRSA is a Javascript/PHP implementation of RSA algorithm which help you to simulate SSL-Like secure data transmission over the net as easy as possible !
