Playground for open source JavaCard applets! All work and no play makes Jack a dull boy.

Applet Playground

AppletPlayground is an educational repository for getting to know JavaCard development by learning from existing open source software.

It includes various open source applets from the internet, bundled into ready to use package. Everything you need to edit, compile and load the applets to real JavaCard-s or test with an emulator.

Time to experiment!

FEASIBILITY NOTICE

The above applets and the overall package comes "AS-IS". I make no claims about the feasibility, usability, security, correctness whatsoever of the whole package or any of the components. Use at your own risk. Everything here is only for educational purposes.

What you need ?

• Preferrably a Unix-like operating system like a recent Linux or OS X with installed JDK 1.7+ (but works also with Windows)
• A working smart card reader* with a driver - preferably a well-behaving CCID one
• A JavaCard card* (v2.2.2 or better)
  • a list of webshops and compatible JavaCards
• Eclipse - get from eclipse.org

* you can work with source code without a card and reader, but for actual testing having one is preferable.

Included extras:

• ant-javacard - for building CAP files (MIT)
• GlobalPlatformPro - for loading the applets to the card (LGPL3)
• JavaCard SDK 2.2.2 and 3.0.3 (Oracle-owns-you-and-your-grandma license)

How to use

• Import this project from Git (or directly into Eclipse) and execute the "toys" ANT target.
• Or use command line and issue ant
• Use the included GlobalPlatform utility to load any of the generated applets (.cap files) to a card

In the pipeline:

• Automatic code hardening with http://sourceforge.net/projects/cesta/ (BSD)
• Automatic card simulation with vJCRE (MIT/GPL)
• Automatic card simulation with jcardsim

Problems with loading OpenPGP applet to NXP JCOP card

Strictly speaking this is not an issue, since this repo is just a collection of applets. But I cannot install most of the applets to my card, so I want to ask here for insights.

Describe the bug
When I'm trying to install OpenPGP or some other "heavy" applets like PKIApplet from AppletPlayground, GlobalPlatformPro fails with SCardTransmit got response 0x80100016 (SCARD_E_NOT_TRANSACTED: An attempt was made to end a non-existent transaction.)

Applets load successfully (package appears in --list), but I cannot create any instances of such applets.

Information about your card
NXP JCOP v2.4.1 R3, appears to have ~1706 bytes of RAM and ~53K of EEPROM (numbers taken from AlgTest applet which loads and runs successfully).

GlobalPlatformPro git hash: f38abc7f0a5ce6bec3a49e3f09cac117f97c7b5d
I tried to reproduce it with different readers and different host OSes, all attempts failed with same (or similar in case of Windows) error.

Expected behavior
Applet is expected to install successfully.

Java card applet installation

Hi
I created an applet in javacard and thats running okay. I can see the CLA, INS etc after building but how can i see the output in netbeans. How is sending the apdu and receiving the output done?

Make a pull request with compilation warnings removed from MuscleApplet and CoolKeyApplet

visible from a command line build with

ant clean toys

Add https://github.com/vletoux/GidsApplet

It is based on IsoApplet and seems relevant here.

Securty hole in the OpenPGP applet

Hi folks,

You should probalby apply this patch:

Yubico/ykneo-openpgp@01fdcc1

openpgpcard has moved to github

More info.
https://sourceforge.net/p/javacardopenpgp/code/14/

Now it's accessible by this URL.
https://github.com/jderuiter/javacard-openpgpcard

Add OpenEMV

http://sourceforge.net/p/openemv/code/HEAD/tree/trunk/src/openemv/

Can I recommend another one?

Not sure if you've seen this. https://github.com/makinako/OpenFIPS201

Encryption/Decryption using java card

I have tried to create a java card applet which performs encryption using AES 128 CBC cipher.I used the Cipher class update() and doFinal() methods for the same. The applet is not encrypting more than 128 bytes.It shows error 6f00 when I send data beyond 128 bytes.Any reason why?

Also I was trying to use Random Data class to generate random data.I was trying to create ALG_SECURE_RANDOM instance but am unable to do so hence I had to use ALG_PSEUDO_RANDOM instance.Can you please help me with the same.

Add https://github.com/LedgerHQ/ledger-u2f-javacard maybe?

Haven't tried it and not an expert in this area, but it seems legit to me.

Update applet codebases
