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...

Java implementation of Shamir's Secret Sharing algorithm as described in Applied Cryptography [as LaGrange Interpolating Polynomial Scheme].

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

HTTPBrute is used to calculate HTTP Digest Access Authentication as per RFC 2617. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response. MD5 is the only hashing algorithm implemented.

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.

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

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.

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

XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)

P.I.G.: Privacy In Gedit, a plugin for gedit, encode and decode text to base64.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

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.

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

A Javascript implementation of the Blowfish Encryption Algorithm described by Bruce Shneier circa 1993. Blowfish is a keyed, symmetric block cipher common in cipher suites and was placed, by Mr. Shneier, in the public domain.

Ramos - McCain - RSA. Cryptographic tool based on the widely-known RSA public-key algorithm.

Encrypted Message Exchange by using Diffie-Hellman key exchange algorithm and Advanced Encryption Standard(AES) encryption algorithm with Cipher-block chaining(CBC) mode using User Datagram Protocol(UDP)port server-client application in C, Ansi-style

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.

A encryption library for C++ "DEL-X" that uses a 3d encryption algorithm. It can work with any key size from 8bit- 4096bit with a 512 byte block size.

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.

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.

...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.

otp.el is a one-time-password implementation in emacs lisp, suitable for generating one time passwords with the MD5 algorithm. It's designed to be plugged in to tramp.

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 !

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.
