An encryption algorithm and UI frontend written in Java.

CertForge is a web-based certificate utility written in Java 1.6, to make or view X.509 certificates, keys, CRLs, manage keystore and truststore (CTL) for SSL sites, and run as a simple Certificate Authority (CA).

The CertMgr application allows you to administrator your own Certification Authority (e.g. for securing your network). You can create, sign and revoke your individual certificates via a simple User Interface.

Certificate-helper is a utility desktop application written in Java designed and created to assist (mainly developers) in creating and viewing keystores and digital certificates. This is done via a user interfaces implemented in Swing.

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.

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.

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.

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.

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.

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.

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.
