Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

Cryptography Workshop is a small yet powerful tool for cryptography and cryptanalysis. It's focused more on classic cryptography. It is currently in alpha and under development.

CryptoHawk can calculate hashes (md2,md4,md5,sha-1,sha-256 and hmac). It can also perform cryptanalysis like frequency analysis for substutition cipher and exhaustive key search for rotation cipher, as well as searching internet databases for md5 hashes.

Cryptol is a domain-specific language (DSL) for specifying and verifying cryptographic algorithms. Developed by Galois, Cryptol provides a high-level mathematical syntax for describing cryptographic primitives and enables formal verification of algorithm properties. It is used in academic, research, and defense sectors to validate correctness and security through symbolic execution and model checking, ensuring critical cryptographic code is free of design flaws.

With this application you can encrypt texts or files and chat with friends. You can download a early Android version of the chat client from here: https://drive.google.com/uc?export=download&id=0BwePHaWdtoMweWRyMExqbHZyUEk Hint: I started this project because i have fun to write java apps. This app is not professional. I don´t recommend using this to encrypt very important data (for example of your company ...). Keep this in mind. Happy testing! ;) Please check MD5 after Download. You can find this on the official site of this project (german). You can find a link to this very simple site below. How to start: -------- Windows: double-click on CryptolinN.exe -------- Linux: sh CryptolinN.sh OR FIRST chmod +x CryptolinN.sh THAN ./CryptolinN.sh -------- Console: java -jar CryptolinN.exe --help N = version number

A small bash script to create, mount and unmount an encrypted partition / file. Using the kernel's cryptoloop, and all encryption cyphers supported.

Cryptomak contains cipher and tools for encryption utility written in php such as substitution, vigenere, affine, transposition and index of coincidence. It is powered by Phrame platform which implements MVC design and Smarty template engine.

Cryptonik-Text is a useful, simple to use tool for encrypt/decrypt text docs, messages, notes etc. Application uses a charset that can be typed from any keyboard (on-screen or hardware). Some national symbols are converted to 26 standard latin letters.

Cryptopus is a ruby on rails web application for storing and sharing passwords and other sensitive data. All data is stored encrypted in a database, safe from third party access.

Pure-Java cryptographic calculator, featuring basic arithmetic operators, cryptographic operations, multiple key file formats and edition of ASN.1 object files.

Crypty is your tool for encrypting and decrypting your private messages and files with security provided by the usage of TripleDES (3DES) or RSA.

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.")

Hide secret messages in your pictures! Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. The vessel images can be 8-bit gray-level images or 24-bit deep true-color images. Anyone who can correctly spot the two vessels and knows the dimensions of the image containing the secret message will be able to decrypt the secret message using the Cyberbit application.

The program uses a number of processes to brute-force crack MD5 hashes. MD5 brute-force cracking involves hashing all possible strings and each time compare the obtained hash to the one we are trying to crack

DES Cracker is a small perl script that cracks DES encrypted passwords.Currently there is only a brute force implementation where phrases are generated. Later version will have a possibility to use word lists for cracking.

DKIM for JavaMail is a small JAR that can be easily implemented in existing Java projects using JavaMail for sending DKIM signed emails.

Starting July 2026, StrongKey will start distributing new releases of its open-source software with digital signatures using the W3C XMLSignature (DSIG) standard. This project distributes CLI and GUI versions of software that can verify the signed package containing the content, signature and certificate chain.

This contains a sample implementation of DTLS-VPN using OpenSSL DTLSv1 Support - to send data over an encrypted channel.

In DeCrypto you will find a collection of scripts for helping decrypt messages. Eventully I am going to put these scripts together into a nice interface.

A new routing protocol called Delay Based Routing Protocol (DBRP). It is a flexible distance vector routing protocol with a metric based on delay. It natively supports IPv4 and IPv6, and can also carry information for common services such DNS servers

With this library, you'll be able to access a smart card and extract its information. If the smart card contains a key store, you can use it to create digital signatures. This library currently implements signing of PDF documents using the Belgian eID.

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.

Compute shared RSA keys for two parties using Gilboa's protocol. Other protocols may be added. Contains JAVA source for Benaloh, Naccache-Stern and Goldwasser-Michali crypto-algorithms. Oblivious transfers and BiPrimaliy tests also implemented.

This is a community effort to study and improve security of WPA protected WiFi networks.
