Project Sypher is a Java program that is intended to take a document and cipher the text, output the result in a new document and delete the original file.

This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

pup2p is a remaster of the Puppy Linux livecd distro and is aimed at use with the anonymous network I2P. It includes I2P as well as a number of I2P related apps. NOTE: The ISO is currently VERY out of date! Sorry for my absence. I may try to update the project soon. The SFS file IS up to date as of this change. 03/2013

Cypher is an encryption program that uses the AES (Rijndael) algorithm to encrypt and decrypt files. You can use Cypher to protect sensitive data from unwanted access.

The Entropy Gathering Daemon is a portable perl script which provides a source of randomness on systems that lack an in-kernel /dev/random. GnuPG, OpenSSH, and the OpenSSL toolkit can use EGD to seed their random number generators.

It is a simple password manager for your PC and Smartphone. It works like a text editor and uses a strong cryptography algorithm to generate the end file.

NeoCrypt is a GUI-based file Encryption Utility for Windows. It helps you to protect your sensitive information easily by encrypting it with password(s).

Generate RSA key pairs of arbitrary length; convert text between formats or use keys to transform/crypt text. Supports decimal, hexadecimal, base64 and text input and output. Entirely ANSI C++; no external dependencies.

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.

A software written in java to compute the digital signature on documents and verify them, using a smart card or a token file in p12 format

MD5 Hash Calculator for VB6 (Module). You can add the module to your project.

SSL-Explorer is a fully-featured, web-based SSL VPN server. This project is no longer actively maintained as the SSL-Explorer technology has now been acquired by Barracuda Networks, Inc.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

Hash is fast and simple java utility program for calculating and verifying checksums for files and text. Hash can generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksum values.

Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography comes from New Latin steganographia, which combines the Greek words steganós , meaning "covered or concealed", and -graphia meaning "writing".

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.

PyKCS11: a complete PKCS#11 wrapper for Python, created using the SWIG compiler. API documentation: http://pkcs11wrap.sourceforge.net/api/

REDACT 3 is an advanced forensic privacy eraser engineered for absolute destruction of tracking data across 250 parameters. Built with a native Windows 11 Fluent Dark UI, it purges deep registry keys (AmCache, BAM, ShimCache), change journals (NTFS $UsnJrnl, $LogFile), AI timeline pools (Windows Recall), and a 10-browser matrix, leaving core OS files safe. For SSD/NVMe architectures, the engine forces controller-level block clearing of deleted data via native automated PowerShell ReTrim calls.
