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

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.

Cyphoogle increases Gmail users privacy by automatically encrypting messages sent through the popular service.

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

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.

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.

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.

Dear Diary is a password-protected text editor with features similar to WordPad that automatically encrypts the text before writing to disk. You can format text with different colors, fonts and font sizes as well as insert images into your documents.

Debaser is a powerful password generator which has plans to be turned into a password manager.

An OLPC project in wxpython, aimed at allowing children to involve their families in certified decision making. All voting is to be based on digital signatures, to get legal binding.

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

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

A one key 64-bit encryption program designed for Linux and Windows. There is a console version, and also a GUI version provided by wxWindows.

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.

Dirt is a multi-platform IRC proxy that adds FiSH-compatible chat encryption (including DH1080 key exchanges) to any IRC client. It can be used as a SOCKS proxy or as a simple bouncer. For security reasons, only localhost connections are allowed.

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.
