MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.

I did not see a pre-built version of this software on the original developers Github project (https://github.com/gaborbata/jpass), so I am taking it upon myself to compile the releases as they come, so that others don't have to. --Description-- JPass is a simple, small, portable password manager application with strong encryption. It allows you to store user names, passwords, URLs and generic notes in an encrypted file protected by one master password. I will not add the source here, as I will not be keeping it up to date. Just the releases as they are updated on his/her github. If you require the source, or want to compile on your own, here it is: https://github.com/gaborbata/jpass

Starting as a personal study project, I have decided to share this security project. For now, it is a JAVA program that can be used to encrypt and decrypt simple file content (ie files), possibly later evolving into a utility with user interface and/or a library

The AWS Encryption SDK is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts.

Ank Zipper provides you with a lightweight, Java-based application designed to provide security to your documents. Ank Zipper can compress both files and folders and create password-protected archives, in order to prevent unauthorized access to important files. Additionally, it can be used for extracting or simply browsing ZIP files.It includes AES(Advanced Encryption Standard) algorithm to encrypt/decrypt file(s). Ank Zipper is a cross-platform software that can be used on any platform that features Java compatibility (e.g. Mac OS X, Linux, Windows).

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

An encryption algorithm and UI frontend written in Java.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

A cross platform implementation of ECDSA (elliptic curve digital signature algorithm) interface to the aSuretee Token.

A library written in Java and C# for crypt,encrypt and generate key pairs using the ElGamal algorithm.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

Enfomi is a cross-platform standalone password-based encryption/decryption program that supports 27 algorithm variants (including AES 256bit). Archives can be self-decrypting, thus making it perfect for mobile applications.

· A free chat server coded in java. · Supports secure connections via the Diffie-Hellman-Algorithm. · One java chat client available. · Other clients in production.

Fileprivacy is a small tool which easily encrypts and decrypts files with common algorithms like AES, Blowfish, Triple DES and RSA. You can either use passwords or keyfiles. Since Fileprivacy is coded in Java it should run on all popular operating systems. #######BETA 2####### Bugfix - Beta 1 stopped working if filename was too short or long - added .exe file ####### NOTE ####### This is an early beta implying there are some issues left. The Keygenerator stops working if you change the algorithm after setting the keylength. It has to be restarted for further use. Because there are no start scripts, yet, you have to start Fileprivacy from console by typing: java -jar Fileprivacy-1.0_<version>.jar ####### ALSO NOTE ####### The author of this software is not responsible for the safety of your data. There is no guarantee that one or more of the implemented algorithms cannot be compromised.

Why FinalCrypt? 1. Most people choose Disk-Encryption as it's easier to unlock a whole drive, but Big-Brother or Malware can then also read all your files. Only use File-Encryption! 2. Most software uses recently broken AES encryption. 3. Soon The Shor's algorithm will instantly break all assymmetric encryption with Quantum Computers. 4. FinalCrypt uses Symmetric One Time Pad Encryption, which is the most unbreakable encryption there is. 5. FinalCrypt is the only "One Time Pad", OpenSource, Cross-Platform, (Bulk) File Encryption Software available.

This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.
