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).

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.

Small stream encryption program for Unix

An encryption/decryption engine which can encrypt any file(text, pdf , doc, rtf , gpg , mp3 , mp4 etc..) or any data on your PC such that only you with the valid password can decrypt it.Also it will compress the file while encrypting it.

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.

DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.

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.

ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key.

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

A program that encrypts multiple files. It uses new encryption algorithms, such as a Three-Block Feistel chiper, ArchFurry's algorithm and a new hash function. Licensed under the ISC.

This project will provide a library for using the AES round 3 cipher candidates (Mars, RC6, Rijndael, Serpent, and Twofish) in an easy to use API. Support for MD5, SHA.

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

B-Trust eDoc is a program built on top of LibDigiDoc a free implementation of the OpenXAdES standard for signing/encrypting files using smartcard tokens. It also contains Openssl and PKCS11 wrapper classes in C++ which might be useful to developers.

An original bruteforce-based encryption/decryption system. BBE was originally conceived to chat with encrypted text on IRC. mIRC and X-Chat support BBE via script addon. BBE can also encrypt MIME encoded files. Blowfish encryption is currently supported.

Cameloid is a new TCP/UDP based P2P voice and video encryption software, that will provide high level of privacy for all levels of communication using only quality secret-key ciphers to ensure long-term security.

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.

Utility to encrypt files and streams. Features: encryption with AES, Serpent, Twofish and many other block ciphers supported by Botan; PBKDF2 key derivation; HMAC verification; does not require files, works with pipe input and output

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

CyberCrypt: ----------------- .NET Library for Encryption/Decryption Usage: ---------- Encrypting file using AES (256 bits): CyberCrypt._AES256.EncryptFile("C:\example.txt", "YourPassword") Decrypting file using AES (256 bits): CyberCrypt._AES256.DecryptFile("C:\example.txt", "YourPassword") Hashing string using SHA512: CyberCrypt._SHA.SHA512Hash("A string that will be converted to SHA512 hash.")

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

Encryptor is an application extended by plugins, it is aimed to provide an interface to encrypt strings. At the moment, the available plugins are: * OpenSSLPlugin * BotanPlugin

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.
