it is about a GUI (Graphical User Interface ) program based on Qt4 library ,that hides data on a picture using differents method depending on picture format (BMP,JPG,PNG,...) (this is called Steganography) the data can be on any file format

Stegano.Net is free Steganography Tool for Windows. It hides texts/files/data in images. The secret data can be unveiled from the Images afterwards.

Steganographia is a very easy application to crypt/decrypt your text in Windows Bitmap.

A program rövid üzeneteket tud elrejteni, kódolni latin nyelvű disztichonos versekben. Dekódolni is tudja az ilyen titkosított üzeneteket rejtő verseket. Ezen kívül véletlenszerűen is tud verseket generálni. Minden generált vers értelmes latin nyelvű költemény.

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.

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.

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.

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.

StrongKey is a building block in an Enterprise Key Management Infrastructure (EKMI), with the goal of centrally managing symmetric encryption keys.

StrongKey CryptoCabinet (SKCC) 2.0 is a FIDO-enabled (fidoalliance.org) web application built using Regulatory Compliant Cloud Computing (RC3) architecture (http://bit.ly/rc3infoq). It encrypts files/objects of any type or size, and stores the ciphertext either to public/private clouds—AWS, Azure, Eucalyptus—or local/network drives, while keeping cryptographic keys safe and secure OUTSIDE the cloud. CryptoCabinet leverages the StrongKey CryptoEngine (SKCE)—another FOSS on this site—to perform FIDO U2F strong authentication, encryption/decryption, digital signatures, and cloud integration. CryptoCabinet is a powerful example showcasing StrongKey CryptoEngine's innovative capabilities. Until you modify the CryptoEngine configuration, the default download uses a DEMO Tellaro KeyAppliance (KA) instance to store cryptographic keys. As such, use this ONLY FOR DEMO purposes. Contact us for any of your production needs. Thanks for stopping by!

StrongKey CryptoEngine (SKCE) 2.0 is a "crypto Swiss Army knife" server to perform cryptographic functions through web services, while freeing application developers to focus on business functionality. Its modules include: - A FIDO Engine to support FIDO U2F key registrations/authentications - An encryption engine to encrypt/decrypt files using AES/TDES keys - Escrowing keys to on-premises key management system (StrongAuth KeyAppliance/SAKA) - Integration to cloud storage services (AWS S3, Azure and Eucalyptus Walrus) - A signing engine to digitally sign documents, code, etc. with FIPS 140-2 HSM support - An LDAP Engine for AD/LDAP integration for authorization decisions SKCE is battle-tested and in production at one of the largest e-commerce companies in the world, protecting more than 50M documents within the business process; see http://bit.ly/14VPYlO for the case study. Download StrongKey CryptoCabinet (SKCC) on this site to see how to use SKCE.

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

The provided program helps the user with the deciphering of a substitution cipher with the 26 letter alphabet by providing the following features • Dynamic entering of ciphertext. Ciphertext can be modified at any point of the process. • Easy location of corresponding characters in the ciphertext and the substituted text by selection. • Fast frequency analysis for single letters, bigrams, trigrams and quadgrams (more N -grams can be made available by adding a single line of code). • Showing the most common letters (bi-/trigrams) in the ciphertext compared to the most common letters (bi-/trigrams) in the British English language. • Easy assignment and change of the substitution letters. • Auto assignment of the 10 first letters.

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.

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.
