Focus on running existing code in a modern container, instead of emulating an old environment to the dumbest details. Fully open source!

vJCRE is a vritual Java Card Runtime Environment that allows to run Java code targeting the smart card platform inside a standard desktop Java virtual machine. Ideal for fast development, testing or experimentation.

Features

• Easy interfacing with any APDU-like interface:
• CommandAPDU from javax.smartcardio
• Generic byte[] exchange, like Android Host Card Emulation
• JavaCard 2.2.2+, usage of Extended APDU encouraged
• HostApduService proxy for Android
• Includes all packages with essential interfaces and abstract classes up to JavaCard v3.0.4:
• javacard.framework.*
• javacard.security.*
• javacardx.apdu.*
• javacardx.crypto.*
• Simple, thin and modular codebase to the finest extent possible.
• Minimal one-liner pollution in javacard*.*. The only allowed import is from pro.javacard.vre.*;
• No Javadoc or license for API specification. Go read the original API docs. (hint)
• Implements necessary JCSystem and APDU, cryptography provided either by standard JCE or BouncyCastle.
• Applet management interface, not unlike GlobalPlatform
• No support for:
• Transactions
• RMI
• Services
• Logical channels
• Future versions
• More algorithms, including JavaCard 3.0.X features
• Multiple independent VJCRE instances in a single VM
• Saving and loading VM instances (real "virtual cards")
• Works great with the rest of the open source smart card stack.
• Made in Estonia

Usage

import pro.javacard.*;
        
VRE vre = VRE.getInstance();
AID aid = new AID(FakeEstEIDApplet.aid);
vre.load(FakeEstEIDApplet.class, aid); // Load the applet with the specified AID
vre.install(aid, default); // Make a default selected instance of the applet with same AID
TerminalFactory tf = TerminalFactory.getInstance("PC/SC", vre, new VJCREProvider());
CardTerminals terms = tf.terminals();
// Now use javax.smartcardio as you would do when talking to a real smart card

Get it now!

Version 0.1 will be released early March 2014 together with FakeEstEID Android version. Until that time feel free to look around in the repository.
