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

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

Clipperz is a web based password manager. Local encryption within the browser guarantees that no one except you can read your data. A true zero-knowledge (or host-proof) web app!

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.

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.

This project is designed to further enhance a method of encrypting URL variables in Cold Fusion Applications. The application itself is not the main bulk of the project. The main bulk of the project is the encryption and decryption routines that go on i

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>

We developed a classic solution that reflects the very nature of quantum mechanics in whole, ultimately demonstrating the raw power of numbers. We developed a truly irreversible one way algorithm which, when applied to information, both encrypts and decrypts it. That is to say that the algorithm which encrypts the information works in the same direction as the algorithm that decrypts it. This in itself is the very nature of quantum mechanics - "forward only". Through a quantum-entanglement-like operation, we created very robust encryption methodology which will secure information for some time to come through sheer numbers and flexibility. With 2^65536 possible keys a brute force attack on a key is simply infeasible. The full version, due to release March 11, 2013 will allow password protection which helps protect your information by forcing the impostor to not only produce the 65536 bit key, but have your password as well and allows for individual passwords for individual files.

Credit Card Vault is a simple app that allows you to store the credit card information encrypted with the 3DES encryption algorithm in CBC mode on an Android device. I originally developed this app for my university course, but I also decided to post it on GitHub on Sourceforge. This application is made for educational purposes only. Despite having well-functioning cryptographic features, it may not be reliable. This application is provided with no warranty or guarantees of any kind. Use it at your own risk! Made with the help of the ChatGPT. The Source Code is available in the GitHub repository: https://github.com/Northstrix/Credit_Card_Vault_Android_App Download shortcut: https://sourceforge.net/projects/credit-card-vault/files/V1.0/app-debug.apk/download

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! ;)
