Open Source MS-DOS Cryptography Software

EverCrack cryptanalysis engine. The goal is cryptanalysis of any class of cipher. The focus now is the kernel - cryptanalysis of unilateral monalpha substitution ciphers extremely quickly, and later, cryptanalysis of complex ciphers for the kernel.

Hide In Picture is a program that allows you to conceal files inside bitmap pictures, using a password. The pictures look like normal images, so people will not suspect there is hidden data in them.

Al2 is a language, close to C++ and Java, designed for use in mathematics and science, but is procedural unlike Mathematica and Maple. Like C++, class operators can be defined. Like Java, there is no need for header files. Aled is an interface to AL2.

SSHDOS is a DOS port of SSH, SCP, SFTP and Telnet clients. Needs a packet driver (or a PPP driver for dialup connection) only. There are two separate packages for SSH1 and for SSH2.

Collection of pseudorandom number generators (PRNGs) implemented in QBASIC/QuickBASIC and avilable as DOS executables.

PGP, short for Pretty Good Privacy, is a public key encryption package; with it, you can secure messages you transmit against unauthorized reading and digitally sign them so that people receiving them can be sure they come from you.

This is a project that simulates the German Military Enigma machine during WWII.. It is a project for beginers to learn to program and to meet people. If anyone is interested in helping, please email me @ dustin@rockhill.org

This library provides crypthographic functions written in plain Object Pascal, aimed to be portable and easy to use. Currently it contains BlowFish Cipher , MD5 and RipeMD hashes. More is planned.

Originally a software partnership between my best friend and myself, Diverse Developments seeks to write "useful stuff", of a very diverse nature... Current projects include a file encoder, and a double-entry accounts package.

EAEScrypt is a utility that is designed to protect sensitive data using secure encryption. It uses the Advanced Encryption Standard (AES) as published by the Federal Information Processing Standards Publications (FIPS PUBS) and issued by the National Institute of Standards and Technology (NIST). The official version of AES allows only 128-bit, 192-bit or 256-bit keys, and EAESCrypt is fully compliant with FIPS-197 when using these values. But EAEScrypt can use any key size from 128-bit to 2048-bit. EAESCrypt is a command line utility. The instaler for Windows 7 provides some basic functionality in the context menu for the files in Windows Explorer, to encrypt and decrypt them, as well as to manage the encryption keys. Go to the EAESCrypt Web Site to download the installer and the source code.

ObscureEncrypt is a high level security encrypter. It encrypts at three levels, 448 bit Blowfish encryption, Obscurity, high level encryption. Making it almost impossible to decrypt

PROJECT HAS MOVED TO GITHUB: https://github.com/alex-georgiou/rc4-32.asm Code to brute force the 32-bit key used to RC4 encrypt .pwl files.
