RC4.NET is a library that adds support for encrypting/decrypting using the symmetric RC4 algorithm in the .NET environment. The library is written in C# language, and performs equally well on both the Microsoft CLR and Mono platform.
This library provides two operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which ensures the implementation is verified against the vectors provided in RFC 3394.

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.
A simple but fully-featured implementation of the simple Caesar Cipher encryption algorithm, specifically 'rot13' - Caesar with a factor of 13. Supports file and tty input/output, internationalisation, and also includes a shared library.
Secure Hash Algorithm variant of the nist maintained Secure Hash Algorithm. this is a 1024 bit digest. Comments suggestions always welcome. Rick
Removed old downloads as they are long outdated. The update is the last version I worked on. Algorithm is based on the SHA2 digest. I may work on an updated version for c++11
Secure P2P Instant Messenger running on .NET Framework 2.0. Uses server to store user information (user name, password, email address, friends list, log in state, IP address) in encrypted form. Uses custom designed symmetric encryption algorithm.
Semeir is a Encryption algorithm, Capable of block encryption. It is written in pure C. It is platform independent, and is promising for Embedded systems. Intended as an alternate, yet secure data encryption cipher.
This is the extended euclidean algorithm implemented in haskell.
It will put every single step of the algorithm in a file and show the actual result and everything in between.
SysK allows to crypt text by using system informations calculate the algorithm.
For each user,the crypt algo will be different.
It's written in C language for Linux x86.
The objective is to allows it to crypt streams, binaries and more.
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.
The Tiny Encryption Algorithm (TEA) was developed by David Wheeler and Roger Needham at the Computer Laboratory of Cambridge University. The variant used was developed by David Wagner. TEACrypt 80x86 is the porting of this algorithm to the 80x86 platform
Private-key, symmetrical (same password to encrypt and decode) file encryption with 8-bit to 2147483647-bit (2^3 to 2^31) encryption using my own algorithm and my own extension of MD5 (http://blog.robtoth.net/2009/06/tencryption-computer-programming.html
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.
Cryptar is a cryptographic network backup program that is able to be very efficient with network resources by using an algorithm derived from the rsync algorithm. It uses SHA-1 hashes to verify (sign) its data and AES to encrypt it.
distDES is a Java RMI-based application which manages load balancing on heterogeneous clusters. Development will extend the theoretical initial implementation to include clustered Rainbow Table generation and encryption algorithm collision detection.
Flash/PHP adaptation of the XTEA encryption algorithm. Allows encryption/decryption of sensitive data using 128-bit key. May be used for network data (HTTP) or offline for implementations like secure CD-ROM projects.
jCryptPad stores text informationen hierarchical, e.g. passwords, important texts etc. The data is saved in a encrypted xml file. Encryption is done with the AES algorithm. Additionally a password generator and a text encryption editor is also included.
