CryptAPI is a C# library that contains unimplemented algorithms in the .NET framework (NT, NTLM, BlowFish, DES and MD5) linking and emulating the crypt() unix function re-programmed in C#. The main purpose is to provide backward compatiblity.
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)
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.
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.
Cryptex is a fast and simple easy to use open source software for encryption and decryption of files and folders. The software has a proprietary format for password management. Cryptex use AES and TripleDES algorithms.
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.
An application presents safe and secure Chat through a certificated point which is the Server. It supports authentication of users using passwords and a simple encryption algorithm to exchange a unique key between the Server and each Client.

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.
A formally verified implementation of cryptographic algorithms using the SPARK programming language. For the complete library proofs of the absence of run-time errors are available. Some of its subprograms include proofs of partial correctness.

Parallelhash is a multithreaded command line utility for hashing a file. It supports algorithms md5, sha1, sha256 and sha512 and can perform multiple simultaneous hash calculations. It's initial goal is to be faster at hashing than dcfldd.
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.
A Javascript implementation of the Blowfish Encryption Algorithm described by Bruce Shneier circa 1993. Blowfish is a keyed, symmetric block cipher common in cipher suites and was placed, by Mr. Shneier, in the public domain.
This is a simple encryption tool to work with home-grown encryption algorithms.
It can run as either a GUI, a command-line application, or a network proxy.
A one stop solution for all your cryptology needs such as ENCRYPTION, DECRYPTION, STEGANOGRAPHY, PASSWORD GENERATOR, PASSWORD KEEPER, HASH CALCULATOR etc.
This WebOS application generates RFC 2289 standard compliant one-time passwords. It supports the MD4 and MD5 message-digest algorithms as well as the SHA-1 hash algorithm and can be used with challenge-response OTP systems such as OPIE and S/KEY.
DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.
