This project contains the code for a Bitrepository client to retrieve salted checksums from a bitrepository and compare these to checksums stored locally. The client also contains a GUI to perform the necessary operations. The program facilitates functionality to:

• Specify the necessary repository settings (and load and save these)
• Provide a list of files with known checksums
• Retrieve multiple salted checksums (for the files in the above list) and compare these to the expected values
• Save the resulting checksum list and comparisons of these

The backend code was developed using a compositional design. Test-driven development (TDD) was use throughout the project to develop the code. A great reference addressing these techniques can be found here

The GUI part of the code was created in Swing using the WindowsBuilder plugin for Eclipse, i.e. a lot of the code in Main.java was auto-generated by WindowsBuilder.

In order to build the project you will need to install Java (version 1.8) and Maven (version 3.3.9 or above). Git will of course also be needed. Do the following to install the project:

• Clone this project and change directory to the folder containing the project
• (Run the tests with $ mvn clean test)
• Build the project with $ mvn clean package

This will build an executable jar and a library folder containing all necessary dependencies in the target/ folder. The program can be run by just double-clicking the jar file or by running the command $ java -jar target/bitmagasin-gui.jar (doing it the latter way will enable you to see the Java log in the terminal).

A zip file containing the bitmagasin-gui.jar file and the necessary dependencies (in the library folder called lib) can be downloaded by clicking the "Release" tab in the menu above.
