Steganopic is a steganography program that hides information in a multitude of file formats without any apparent change to the original file.

This is a PHP library that can be used to hide data (messages or files) in images using steganography techniques. The data in the image only exists symbolically and thus only you and the intended recipient will know of the existence of that hidden data.

Sterlingcoin is a digital currency used to pay for goods or services in daily life both offline and online. It is a decentralised system controlled by an open market and not by a corporation, bank or government. Because of its decentralisation everyone who runs the Sterlingcoin wallets shares the public ledger*. Sterlingcoin is a completely fair**, transparent and a highly secure form of currency for all needs. The price of Sterlingcoin is determined by supply & demand, use, trading and mining***. *Transaction history of every Sterlingcoin wallet **A limited supply of money would allow for a better economy; where ‘better’ means ‘fairer’, more stable and devoid of government intervention. ***Maintaining the block chain is called mining, and those who do so are rewarded with newly created Sterlingcoin and transaction fees.

Stream Shield is a program to encrypt and anonymize your connection to the internet by connecting to remote proxies, using Blowfish/Rijndael Algorithms and removing many personally identifiable headers such as referer, user-agent and more.

Strip is a password and account managment program for the Palm(T) Computing Platform. Designed to fit the needs of both IT professionals and the average user, it combines ease of use with flexibility and security.

StrongHold32 - is a stand alone crypto program created for Win32 . It is based on the RC5 family (32/0..255/0..255). Easy to use and fast. Process any file types. Tool supports one click multiple files encryption and fast e-mail processing.

A console-based tool for Linux that will provide simple functionalities to help decipher substitution ciphers.

This substitution cipher toolkit enables you to en- and decrypt texts with substitution cipher, to gather language statistics of a specific language and to crack encrypted texts both manually and automatically. All functions can be accessed via an easy-to-use graphical user interface.

Line command cleaner/converter files.

This is the extended euclidean algorithm implemented in haskell. It will put every single step of the algorithm in a file and show the actual result and everything in between.

Swift Crypto is a cross-platform, open-source implementation that mirrors a substantial portion of CryptoKit so server and Linux/Windows ARM64 apps can share one modern crypto API. It exposes high-level, misuse-resistant primitives with Swift ergonomics while delegating to well-vetted backends under the hood. The repository maintains active releases and issue tracking for enhancements like PEM handling and ecosystem compatibility. High-level, misuse-resistant primitives and key handling. SwiftPM distribution for easy inclusion in builds. By matching CryptoKit’s surface, it reduces portability friction between Apple platforms and server environments. The package slots cleanly into SwiftPM builds and is widely adopted across the Swift server ecosystem. Its goal is practical cryptography: safe defaults, clear APIs, and predictable performance.

SwiftCrack is a wireless LAN (WLAN) tool which recovers encryption keys. SwiftCrack operates by proactively monitoring transmissions, injecting traffic with known key streams, computing the encryption key when enough packets have been gathered.

TC-Wrapper is a Windows service which opens/closes TrueCrypt containers automatically using an USB-Stick with a key file. Containers are even mounted if you are not logged into your system.

The Tiny Encryption Algorithm (TEA) was developed by David Wheeler and Roger Needham at the Computer Laboratory of Cambridge University. The variant used was developed by David Wagner. TEACrypt 80x86 is the porting of this algorithm to the 80x86 platform

The CDSA Java Interface project allows you to use CDSA services as JCA-JCE services from your Java applications.

TLS Lite is a python library for SSL/TLS. It supports non-traditional authentication methods such as SRP, shared-keys, and cryptoIDs, as well as X.509 certificates.

TSEFS is an encrypting filesystem.

A client-server-system for distributively editing and signing documents. (technologies: Java, Java Servlets / JSPs, EJBs)

An implementation of a Non-Interactive Zero knowledge Proof system to be used in a voting simulation software, as part of our BCS project.

Fast cryptography extension for Tcl. TclTomCrypt is a sensible binding that brings the features and performance of LibTomCrypt to Tcl.
