JCrypt

JCrypt is an application that lets you encrypt/decrypt (cipher/decipher) files with a password through two ways :

• From a Graphic User Interface (GUI)
• From a Command-Line Interface (CLI)

It is based over the Blowfish algorithm provided by the Java Development Toolkit (JDK).

The Graphic User Interface

The GUI is designed to be as straightforward as possible, simply select the operation and options from the lower button bar then drop your files/folders in the specified area. You will be prompted for the password key and the output folder (if needed) during the process.

The Command-Line Interface

usage: jcrypt-cli
    --compress                                 Compress output
    --help                                     Display this help
    --input <INPUT DIR OR FILE>
    --key <KEY>
    --operation <C (cipher) or D (decipher)>
    --output <OUTPUT DIR>
    --verbose                                  Display debug infos to std

for example :

/usr/bin/java -jar /root/bin/jcrypt/jcrypt-cli.jar --input ${dumpfolder} --output ${dumpfolder}/encrypted --operation C --key myComplexPassword --compress --verbose >> /var/log/jcrypt/dumpscripts.log

Building

In order to build JCrypt, you will need Maven and a JDK8.

mvn clean install

When build is successful, resulting jars should be put in their respective target folders.

Note that both cli and gui jars need the base library (jcrypt-metier.jar) to work. Please make sure that this jar is added to the classpath.

Note that a .exe wrapper is available for Microsoft Windows here with or without the Java Runtime Environment : https://github.com/dwarfman78/jcrypt/releases
