Java class file encryption. Class Encrypt is a program that can encrypt a developer's class files and package them into an executable jar file for deployment. The program uses modules for implementing different encryptions.

Hasher is a .NET class library to help programmers implement standard hashing and checksum algorithms into their own software. Written entirely in C#, Hasher providers a uniform interface to easily use any of the algorithms contained within this library

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

The Amazon DynamoDB Client-side Encryption in Java supports encryption and signing of your data when stored in Amazon DynamoDB. A typical use of this library is when you are using DynamoDBMapper, where transparent protection of all objects serialized through the mapper can be enabled via configuring an AttributeEncryptor. Use SaveBehavior.PUT or SaveBehavior.CLOBBER with AttributeEncryptor. If you do not do so you risk corrupting your signatures and encrypted data. When PUT or CLOBBER is not specified, fields that are present in the record may not be passed down to the encryptor, which results in fields being left out of the record signature. This in turn can result in records failing to decrypt. For more advanced use cases where tighter control over the encryption and signing process is necessary, the low-level DynamoDBEncryptor can be used directly.

Lanchat is a Client/Server instant messenger chat service for network/internet use. Builds upon the many features of modern IM environments while implementing some unique ideas. Supports text formatting, blocking/banning, direct connections and much more

CoDec is a Java package for encoding and decoding ASN.1 data structures. CoDec supports the Basic Encoding Rules (BER) as well as the Distinguished Encoding Rules (DER) and provides a library with data structures for many cryptographic standards.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.

For content encryption, the use of Java's facilities is being considered as a long term option.

This project is considered dead by me(The maker). please visit http://tuxcoder.sourceforge.net/ for the newer version.

This its a simple project of the RSA algorithm. The purpose of this project isn't to develop an impressive program, it's an easy understand of the algorithm and the C programing.

CommCA - A Community-driven Certificate Authority for distribution of free X.509 digital certificates for personal email and server use.

Commando is a military-grade secure communication system.

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

A multithreaded GUI based encryption software that can encrypt any file on any platform.

Tool "Contego" for encryption to plain text (UTF-8) and verification, testing and generation of MD5 and SHA-1 sums for files. Version 2.0 multilnguaje and fully operational. Encriptacion para texto plano (UTF-8) y utilidades para sumas MD5 y SHA-1.

Convolutional Hashing Algorithm. Provably secure hashing algorithm based on worst case assumptions on cyclic-lattices.

This program can encrypt / decrypt strings with the Caesar's Cipher. It also can try to crack an encrypted string with brute force. (C) Daniel Steinhauer <pik-9@users.sourceforge.net>

CrococryptQuerl =============== CrococryptQuerl (CQuerl) is a web-based open-source file encryption and file exchange tool. If you trust the application service provider which is running CrococryptQuerl, it can be seen as an "anonymous & encrypted safe deposit box for computer files". ---INTRO--- The encryption is done on-the-fly using the user's password. Of course, this requires a trusted TLS/SSL connection to the server running CQuerl. The user provides a file and password and receives an ID. No plaintext data is stored in CQuerl including filenames. If the user looses the ID or forgets the password, the encrypted file cannot be recovered - even by the service provider. DOWNLOAD ======== * A demo running on Google's App Engine (GAE) can be found here: https://crococrypt-querl.appspot.com ==> GAE limits the files to be uploaded to 1MB(!). ==> The file database will be cleared occasionally. ==> Crypto seems to be working slowly on GAE, so be patient! ;)

A library written in Visual C# for encrypting a text message into an image file, and decrypting an image file to get the text message using Rijndael Algorithm, RSA Algorithm, and LSB Substitution Algorithm.

NetBeans, pure Java. The Cryppie can protect your files by encrypting its content, possibility to compress files before encryption. It's destination for keep information in safe on your flash drive or another storage.

Cryproc is module for the Linux kernel 2.6 which allows user space programs to access the kernel's CryptoAPI functions via a file called "cryproc" created in the /proc filesystem.

Crypt is the developed based on the ASCII Table shift and it can customized based on the user requirements, right from the shifting order and the level of encryption or decryption. It can be integrated to any of the programming language with the custom build of the source code. It can secure from text file to binary code.

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.

Crypt-EG is an easy visual cryptosystem program that implements ElGamal method using elliptic curves.
