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.

The DosUtils project is an attempt to provide many small, helpful, free utilities for easier computer administration and programming on a DOS / Win9x system.

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.

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

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.

Password generator. The user can choice the characters, write the results in text file, make pronunceable passwords, choice the number of digits and codes. Visual version made in Java and non-visual version in C. Great performance.

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

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

This project is based off of Sam Rape. The final product is a bootable floppy which copies the sam file, compresses it and puts it on a disk. A detailed description can be found at datastronghold.com/archive/t10429.html

The SXMD (" like Security-X MultiDistribution ") use syslinux, grub4dos and others bootloaders to recover a crashed boot or run many GNU / Linux utilities. The first category is "Antivirus" with editors like Antivir, AVG, Comodo, DrWeb, FSecure, Kaspersky, Panda, VBA ... The second is composed by GNU/Linux's Distro: DSL, CorePlus (+Qemu Starter), Slacko, Slax Custom, Slitaz & XPuD ... After, you can find very good Recovery and Partitioning tools : Redo Backup, Parted Magic, MiniTool Partition Wizard, Paragon, PING, OSF and ActiveBootDisk ... SXMD also gathering a XP PE : Hiren'sBoot with DOS tools ("ubcd"), a Portable Suite and many boot priorities or possibilities. Size : +/- 3Gb Available : USB / DVD version ("coming soon") WebSite : http://www.security-x.fr/tools/SXMD ("under construct")

dosvstop: dos-TSR program to prevent dos-virus being loaded into memory, could be used with free-dos,

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.
