Infranet is a system that attempts to circumvent web censorship by allowing clients to surreptitiously request sensitive content via cooperating Web servers distributed across the global Internet.

This project provides an interface to Sun's JCE (Java Cryptographic Extensions) as a JSP taglib. It brings strong encryption algorithms such as AES and Blowfish to your JSP applications. It uses the bouncycastle.org cleanroom JCE 1.2.1 implementation as

This library provides a SecureRandom service, integrated with the Java Security API, for accessing random.org and random.irb.hr (true random number generators that generates randomness via atmospheric noise or photonic emission).

mkpass is a simple command line utility to generate secure random passwords. You can easily redirect these to a clipboard or copy and paste as needed. I use a password manager and generate random passwords every time I need one. And while most password managers include a generator, there are times I need one outside of that. The code is written in java so it should run on any OS that supports it. Lastly, the idea and core code came from a Wikipedia article. I just took this and expanded upon it. https://en.wikipedia.org/wiki/Random_password_generator This is a single executable JAR file. While you will need Java installed, there is no need to install this program. Just download the JAR file, please it somewhere convenient, and execute it from the command line: java -jar mkpass.jar See home page for additional details and usage instructions. https://github.com/frossm/mkpass

Application which allows encrypting text. It is encrypted using own libraries. I think it is a very strong way to encrypt, specially if the text has more than 1 KB. The application reads encrypted bytes from disk, and writes encyrpted bytes to disk, so it never is saved in the hard disk decrypted. JDK-17 compatibility. You will find more about it at this web site: https://www.frojasg1.com:8443/downloads_web/web/html/encriptadorDeTexto.html?origin=sourceforge

A library for easy use of symmetric encryption and decryption in java. Encrypt and decrypt with one line of code using common algorithms like AES. Requires Java 7 or later.

Program takes (currently) english text sentences, and replaces each word in a given sentence with another word having the same Part of Speach (POS) tag. This creates a new sentence containing none of the original words. This new sentence can then be transmitted to a remote user, and using the same software, "de-crypted" into yielding the original sentence. The software relies on having a known "seed" value for the random number generator, which is known only by the sender and receiver. It also relies on the sender and receiver having a shared (identical) vocabulary file. The project contains code to test input sentences for inclusion of words in the current vocabulary, and can create entries for new words as needed. The vocabulary has a "MD-5 hash" value to make sure that the share vocabulary file is identical for both sender and receiver. The software also contains a "bad-words" list of words that should never be generated in the text to be sent.

TCPFile is a friend to friend file sharing / instant messaging Java (1.6) program offering zipped and fully encrypted (RSA, AES) communication.

Barada (Barada Aint Respecting Any Deceptive Adversaries) is a PAM module designed to provide two-factor authentication support. There is companion software called Gort which runs on Android devices, essentially turning your phone into a SecureID token. The PAM module is available in the repositories for Debian based distributions. Gort, the Android client, is available from the android market (https://play.google.com/store/apps/details?id=net.sf.crypt.gort)

HashserGUI is a GUI interface for Jacksum. It is intended to provide a graphical tool to create hashes for files within a directory, and check the hashes generated. It works with many hash functions, as md5, sha1, sha256, sha512, md4, crc, etc.

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

It's a cross platform utility designed for performing various checksumming activities. It supports verity of standards including ADLER-32, CRC-32, MD2, MD5, MURMUR-32, MURMUR-128, SHA-1, SHA-256, SHA-384, SHA-512 and SIPHASH24. Also generated results can be validated within the application. Results can be saved to a text file format. It can batch process folders as well. This tool requires Java Run-time Environment 7 or higher to use.

S/Key Generator. An RFC2289 compliant One-Time Password generator written in Java language and O.S. Thinlet package for GUI. It uses MD4 and MD5 hash algorithms.

“Scramble your social network data!” - With Scramble you can selective enforce you access control preferences for your content on social networks like Facebook or Twitter ...

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

A Security tool that will help to verify the hash codes of files . Currently,Our Hash Code verifier tool supports the following Hash types: MD5,SHA,CRC32. More details about the tool can be found in the project homepage.

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.

Crack the encrypted passwords (MD5,SHA, etc....)
