ScatterStorm Mosaic Image Encryptor is not your father's stegonagraphy engine. It's purpose is not to sneak data around in image trojan-horses as much as to be able to reversibly scramble an image (or parts of one) in a mosaic cloud

Projeto de software parte integrante do trabalho de conclusão de curso de Tetri Mesquita Neto, do curso de Bacharelado em Informática, na Universidade Estadual do Oeste do Paraná - UNIOESTE, campus Cascavel-PR.

A steganography tool. You can hide 2Gb file in multiple images, supported almost all graphic formats. Average capacity ~ 40%. Useful for publishing censored materials in the Internet. Details on the project's website (stegoshare.sf.net).

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.

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.

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.

U-Tranz is a free application developed on the characteristics of UDP allows the transmission of unlimited file size. Most of the applications based on UDP restrict file sharing upto 64kb which makes transmission less efficient on large files. Along with the tremendous increase in file size, certain features like implementation of Government Standard Security Algorithms (AES-256*/RSA-2048 and SHA-512) have been added to this application for secure sharing of huge files across different workstations.This tool programmed in JAVA and requires Java Runtime Environment to use this tool. *Unlimited Strength Java Cryptography Extension Policy Files for the Java SE Runtime Environment 7 required to use this feature.

[UPDATE! - VenSafe 2.0.1.2) VenSafe, the best of its kind; A Folder/USB locker software by Rahul M. The all-new VenSafe is ready with its simple, smooth and friendly GUI. This version is far more secure comes with all kinds of bugs, bypasses and cheats fixed. The password can no longer be edited by others from outside. Everything's in the Settings. It's impossible to crack through your folder once it's locked. In case you forget you VenSafe password, you can request for a recovery mail or display it on screen after a small process of Security questions. You can setup your recovery mail in the settings and get the VenSafe password. In case of entry of an incorrect password, it gets stored in the logs and the logs are sent to your mail immediately, if opted so in the settings. VenSafe is highly customizable to suit users' needs.

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!

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.

You can calculating md5 hashsums, comparing files and hashsums in pairs. If you have backups of one file and you have a md5 hashsum, you can compare your backups against this md5 hashsum. Calculating SHA256 hashes too. This repository will no longer updated! Please take a look at this url: https://github.com/tualatin/winmd5checksum

A C++ library implementing the XML DSIG and XML Encryption standards. Based on the Apache project's Xerces (DOM/SAX parser) and Xalan (XSL/XPATH processor) libraries.

fm (file masker) is an easy-to-use command line cryptographic tool that's small, portable across operating systems, quite secure for most purposes, and licensed to you along with its source code under the gpl.

An API and test suite, or possibly an application unto itself, to manage keys and allow mail user agents (such as pine or mutt) to use encryption and authentication systems (such as S/MIME) via the services of external encryption suites (such as OpenSSL)

Library to encode and decode text or files to base64.

A distributed and dynamically threaded password cracker. Completely cross-platform using Qt 4.3. Utilizes 1 server and N clients to distribute password cracking across N machines, each of which can utilize N CPUs.

p12_import is an utility created to import pkcs#12 file into a pkcs#11 device. It could be used in place of Netscape/Mozilla, if there are troubles using the crypto device with other pkcs11 compliant application.

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.

designed to hide messages in jpg and png images without the requirement for any plain-text files. uses aes256 on data, using an sha256 hash of the password as the encryption key. rotates the password by 1 character, and uses an sha256 hash of that for the random seed for the image pointer access. security and invisibility of data is currently being peer-reviewed (since ~2014). At this point it looks like no vulnerabilities have been identified yet. this will evolve further, but remain a console / command application. I will be adding some additional supported file types soon (thinking mp3...). includes (default) option to compresses message with zlib before encryption any ideas / suggestions would speed up the process. This software is intended to be run on a system under the user's control (so keyloggers etc. are not considered).

A ultrafast lightweight (no GUI) encryption/decryption software using the CryptoAPI on Windows platform, to secure just about anything - regular files and directories, consoles, communication resources(COM ports), Disk devices, pipes and sockets anythin

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.
