HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.
A program that encrypts multiple files. It uses new encryption algorithms, such as a Three-Block Feistel chiper, ArchFurry's algorithm and a new hash function. Licensed under the ISC.
A program for encrypt/decrypt files or text inside clipboard with a password or a certificate located either in certificate storage (certmgr.msc) or in a .cer file. You just have to drag and drop files and folder to the application.
Projects, docs, chat, and AI in one workspace. Work faster, not across 10 tabs.
ClickUp replaces your scattered tool stack with one AI-powered platform. Stop paying for project management, docs, chat, and time tracking separately when they all live in one place. Teams that consolidate into ClickUp cut software costs and move faster because everything is connected, not siloed across apps that don't talk to each other.
Implementation of Rijndael, RSA and El Gamal ciphers as well as SHA256, Blake and Blue midnigh wish hash functions. The program is for encrypting files but it can be rewritten for other purposes.
A simple encrypter. Uses various encryption algorithms including but not limited to: AES, Twofish, RC4 and IDEA. To enable the stronger encryption standards such as AES the user must have installed the unlimited strength jurisdiction policy files.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)
openSMS4 was created by tao.tang316 and implemented in C, which is an open source implementation of the SMS4 encryption algorithm (including simple checking codes).
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.
This simple encryption program, allows you to virtually encrypt all documents and even decrypt them back using the secure XOR encryption algorithm. This program is designed for beginners who know little about encryption.
A small encryption / decryption application that we are giving away free of charge.
Version 1.0.00 - RSA only at the moment.
But later versions will have a plug-in system for adding more algorithms.
A Visual Basic implementation of Bruce Schneier's Solitaire Encryption Algorithm that encrypts plain text by means of a deck of ordinary playing cards.
The DemocraKey is a portable privacy suite to ensure your security and anonyminity on while browsing the internet. No more viruses from browsing the web. Just install to a USB Key, iPod, the Desktop or even an external hard drive, and you're ready t

File hashing with md5, sha and ripemd160,
compresssion with gzip, and a nice user interface.
Created using C++ with Qt framework, depends on QCA third-part Qt Library and OpenSSL.
Perfenc is a encryption program that encrypts/decrypts files or the standard input with a one-time pad.
More information about one-time pads is available at http://en.wikipedia.org/wiki/One-time_pad
ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding.
ShredBitz is a very powerful tool.
Simple tool for file encryption and folder content encryption with AES 256. Files can also be hashed with a SHA1 signature. A command line version is available as well as a GUI version. One other useful feature is to encrypt messages for emails.
A GnuPG Frontend GUI made in C#. It is compatible with PGP as well so it can be a very useful tool for encryption/decryption. It also incorporates a shell extension so it can be easy to right click and decrypt or decrypt.
