JavaCard Tutorial

Examples from Eric Vétillard's tutorial re-arranged in a Gradle project using JavaCard gradle plugin with additional tests

Each example is referenced as a Gradle module with :

• source under main sourceSet (sdk version can be selected from build.gradle)
• simulation tests using JCardSim
• unit test using JUnit
• tests on smartcard device using jnasmartcardio with apdu4j logger
• quick testing scripts defining some gradle task to send defined apdu sequence

It's also possible :

• to use GPTool and GlobalPlatform class under test which provide the same power as GlobalPlatformPro tool
• to use GPExec gradle task to call GlobalPlatformPro from gradle to create custom tasks

Setup

git clone git@github.com:bertrandmartel/javacard-tutorial.git
cd javacard-tutorial
git submodule update --init
