GlobalPlatformPro (GPPro) is your go-to tool for loading and managing applets and keys on JavaCards, all from the comfort of your command line or Java project. This user-friendly platform provides a “Do What I Mean” approach, ensuring that most operations are straightforward and hassle-free. In this article, we’ll guide you through the basics of using GlobalPlatformPro, and provide troubleshooting tips to help you sail smoothly.

Getting Started

To begin using GlobalPlatformPro, you’ll need to install it first. Follow these steps:

• Clone the repository or download the latest release from here.
• Follow the setup instructions found in the Getting Started guide.

Installing an Applet

Once you’ve set up GlobalPlatformPro, installing an applet is as easy as pie. Here’s a simple command you can use:

$ gp -install HelloWorld.cap -privs CardReset -params 48692074686572652C2077686174277320796F7572206E616D653F

This command initializes the installation of the applet `HelloWorld.cap` with CardReset privileges.

Understanding the Output

When you run the installation command, you will receive output similar to the following:

Warning: no keys given, defaulting to 404142434445464748494A4B4C4D4E4F
HelloWorld.cap loaded: com.example.helloworld A048656C6C6F576F726C64
$ gp -l
Warning: no keys given, defaulting to 404142434445464748494A4B4C4D4E4F
ISD: A000000151000000 (OP_READY)
Parent:   A000000151000000
From:     A0000001515350
...

To explain this, think of GlobalPlatformPro as a librarian in a vast library of applets (books). When you ask the librarian (run a command) to find a specific book (install an applet), the librarian first checks if you have the key (authentication). If not, they’ll default to their usual keys (404142434445464748494A4B4C4D4E4F) to keep things secure but accessible. The librarian then confirms the book’s arrival (app installation) and gives you a detailed list of all available books (installed applets) in the library.

Getting Information About Loaded Applets

To view loaded applets on your JavaCard, simply run:

$ gp -l

This will display all the currently loaded applets along with their privileges and parent information.

If you encounter any issues while using GlobalPlatformPro, here are a few troubleshooting ideas:

• Check that you have all required permissions and keys set up properly.
• Ensure you are using the latest version of GlobalPlatformPro by checking for updates on GitHub.
