PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing correct handling of all byte values (0–255) without loss, making it compatible with any type of string or binary-compatible data. Main Features Complete implementation of Shamir Secret Sharing Arithmetic over GF(257) Compatible with all character strings Robust Lagrange interpolation Safe modular inverse computation Shares encoded in hexadecimal (3 characters per byte) Clear, well-commented source code ⚠️ Disclaimer This project is intended for educational and demonstration

Qryptix consists of a PAM object and utilities for session- and key-management for encrypted home directories using the International Kernel (CryptoAPI) patches for Linux. It simplifies login/logout, mounting/unmounting, and key generation and changing.

The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. During the desing phase, some other features were added, like encryption and error correction.

Provides efficient, effective implementations of 32- and 64-bit hash functions based on Rabin fingerprints / irreducible polynomials, in Java. Also provides integration with java.security.MessageDigest API.

The Racal Simulator Library is an implementation of a software emulation of the Thales (formerly Zaxus, formerly Racal) RG7000 Host Security Module cryptographic device. (Note: This project is now hosted at Codeplex as ThalesSim).

RainDoll aims to be an implementation of a symmetric-encryption utility for desktop users written in C#/.NET and Windows Forms with two goals: security and simplicity. It uses cryptographic standards for security, and has a smart, compact interface.

NEW VERSION 3.0 NOW AVAILABLE FOR DOWNLOAD!!! This is a random password generator with usefull features. Its fully customizable, compact, it has eye pleasing modern interface and easy to use options. This program makes passwords for you and has options like copying password, pasting it to the desktop, sending it by email. It has a passsword strength meter which evaluates password strength. Big advantage of this program is that you can choose from which letters, digits and all kinds of signes your password will be made. IMPORTANT: Microsoft .NET Framework 4.0 Client or Full and Microsoft Visual C++ 2015 Redistributable are needed to run the program. Download links are in readme(version log). To go to readme file click Files button.

A Plugin for Pegasus Mail, supporting S/MIME Encryption, Decryption, Signing and Signature verifying. In addition, key management is provided.

The SLAN project is a GPL open-source project providing a cross platform Virtual Private Networking (VPN) solution focused on providing secured and accountable links over insecure broadcast media such as 802.11 wireless LANs and public ethernets.

SPipe (Secure Pipe) is a patch of mod_ssl package which allows the same corporate web server to be used as a secure access door to internal servers that do not use HTTPS protocol, while also retaining normal web server functionality for all HTTP requests

With this software, you can embed the text message into a graphic file. The result file looks exactly the same with the original. But if you use this software, you can see the hidden text inside the pciture

The CRY utility provides the ability to perform AES-256 symmetric key encryption of files. This is a light weight Linux utility and does not depend on PKI infrastructure. Rather, pre-shared encryption keys are used to protect your files.

StegoGO is an open source software that allows the embedding of hidden data in GO games, using GNUGo. It allows both the embedding of hidden data in an already existing GO game, and the creation of new GO games to hide data.

TEncryptor Open Source app Written in Python3 and PyQt4 Licensed under the MIT License When you encrypt a text file or message The User need to choose 3 things 1- Password 2- The order of the letters 3- Four letter/word with specified order

A set of tools for manipulating and solving pencil-and-paper style ciphers, cryptograms, and related puzzles.

Utilities for measuring characteristics of cryptographic hash functions: avalanche property, (partial) collision search, Maurer's universal statistical test, Filiol's Mobius ANF statistical analisys. EdonC, EdonR, MD5 and SHA-1 hash-plugins included.

Anoncrypt by HTCoders is a web based Text Encryption and Decryption Project using Java Technology following Struts2 Framwork . It Consist of two modules > Password based Encryption (Symmetric Encryption) > Self-Destructible Message Service (Once the message is read , it is destroyed and cant be decrypted again .)

The File Shredder securely shreds files by overwriting them before they are deleted. Every character in the file is overwritten with customised random data, so it is secure, but a little slow. The file is also given a random name.

UKey is an extension to the open-source encryption tool: TrueCrypt. With UKey you can use a USB key as replacement password for TrueCrypt. Currently the project is in a 'proof of concept' state, meaning it does work but it is not meant for daily use.

USSI is the Universal SAFE Signing Interface. USSI provides web services for the application of SAFE digital signatures for PDF, text, xml, etc. Please see http://www.safe-biopharma.org for more information on SAFE.

An extremely versatile neural net. Hopefully.

This command-line utility produces a report of file information including version information where available. The reports can be useful for release information, manifests, and integrity verification.

Vigenère is a program for encrypting and decrypting text using the Vigenère cipher. Built-in cryptanalysis tools make it possible to crack the cipher without needing the key — or even knowing its length.

Il Wifi-Gateway è un captive portal che permette l'accesso al network mediante vari metodi di autenticazione quali: CRS/CNS via IdPC, One-Time Password, Radius server, SMS ( tramite Skebby ). Il sistema è basato su CAS, NoCat e NoCatCAS.
