How do you find anything in the mountain of data on your PC? How do you organise, maintain, archive and protect your files? How do you avoid surrendering to the Powers of Darkness? Checkpoint Commander, the vital tool for Information Management!

A secure and centralized way to get checksums of common downloads. You will find the usual MD5 hash, but also the newer and more secure hashes like SHA-1, SHA-256 and even SHA-512. If the filesize and all up to four hashes match, you should be save to use that downloaded file.

The functional objective is to provide a simple secure socket infrastructure for client/server apps. The usability objective is to allow inexperienced developers to deploy the system and write "Hello World" with a single page of documentation.

CivilAction lets you create a Choose Your Own Adventure type story that can be played on Java enabled cell phone. A desktop application lets you write story files. People run the story on their phone. Make a 'Tresure hunt' or 'Amaze Race' type game.

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.

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.

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)

Complete digital certificate authority for research & enterprise environments.

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

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! ;)

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.

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

Cryptographic Java library for creating, maintaining, persistence and use of cryptographic entities.

The Crypthing project aims to develop cryptographic software for business, government and personal use within the context of Brazilian Public-Key Infrastructure.The first delivery is an application to sign documents for non-repudiation purposes.

Cryptix is an international volunteer effort to produce robust, open-source cryptographic software libraries. Cryptix products are free, both for commercial and non-commercial use and are being used by developers all over the world.

Cryptix OpenPGP is a library which implements the OpenPGP standard (RFC 2440) in Java.

This is a JavaScript library which gives the ability to use cryptographic functionality abstracted of available technologies on the browser side. It executes a cryptographic function with the fastest technology including Java, JavaScript and Flash.

v2.0.0 (Latest) ---CHANGE LOG--- v1.0.0 - Original Release v1.0.1 - Source Code Cleanup v2.0.0 - Now Features File Encryption Protect your privacy! Encrypt your messages and files with a cryptographic strength of up to 256 bits before sending them to others!

TextConverter is a graphical text editor allowing the user to encrypt/decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher.

Cryptography Workshop is a small yet powerful tool for cryptography and cryptanalysis. It's focused more on classic cryptography. It is currently in alpha and under development.

With this application you can encrypt texts or files and chat with friends. You can download a early Android version of the chat client from here: https://drive.google.com/uc?export=download&id=0BwePHaWdtoMweWRyMExqbHZyUEk Hint: I started this project because i have fun to write java apps. This app is not professional. I don´t recommend using this to encrypt very important data (for example of your company ...). Keep this in mind. Happy testing! ;) Please check MD5 after Download. You can find this on the official site of this project (german). You can find a link to this very simple site below. How to start: -------- Windows: double-click on CryptolinN.exe -------- Linux: sh CryptolinN.sh OR FIRST chmod +x CryptolinN.sh THAN ./CryptolinN.sh -------- Console: java -jar CryptolinN.exe --help N = version number

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.
