Load and manage applets on compatible JavaCards from command line or from your Java project with a Do What I Mean approach.

Provides an easy to use and high level interface that most of the time JustWorks^(TM), is flexible and 100% open source!

Beware: until v0.5 is released, both command line and Java API are subject to change without notice. Check back often.

Command line samples assume default test keys of 40..4F. If you need custom keys, specify them with any or all of the following options: -keyid -keyver and -enc -mac -kek or -key (for a single master key). You need to know the details or ask your card provider. Some cards require key diversification with -emv or -visa2 (you should be notified if that's the case).

• Show some basic information about a card (failsafe):

   java -jar gp.jar -info
  

  • On Windows just replace java -jar gp.jar with gp.exe like this:

       gp.exe -info
    

  • On Linux it is easier to add an alias to the shell like this:

       alias gp="java -jar $PWD/gp.jar"
       # Now you can avoid typing java -jar and gp works from any folder
       gp -h
    

• List applets (this and following commands open the secure channel and thus can brick your card with wrong keys!):

   gp -list # or gp -l
  

• Delete current default applet:

   gp -delete -default
  

• Delete module D27600012401 and all applets from it:

   gp -delete D27600012401 -deletedeps
  

• Install applet.cap as default applet (with AID information from the CAP):

   gp -install applet.cap -default
  

• Install applet.cap (with AID information from the CAP):

   gp -install applet.cap
  

• Unistall applet.cap (with AID information from the CAP):

   gp -uninstall applet.cap
  

• Set 010B0371D78377B801F2D62AFC671D95 key to a card with default 40..4F keys:

   gp -lock 010B0371D78377B801F2D62AFC671D95
  

• Set default 40..4F keys to card that was previously locked with key 010B0371D78377B801F2D62AFC671D95:

   gp -key 010B0371D78377B801F2D62AFC671D95 -unlock
  

• Set the default 40..4F keys to a card that uses EMV diversification (like G&D):

   gp -emv -unlock
  

  * note that you will have to use --relax option after this operation to get rid of the warning about probably needed diversification, which is not true any more.

• Set the default 40..4F keys to a card that uses VISA2 diversification with the well-known mother key on a Gemalto card:

   gp -visa2 -key 47454D5850524553534F53414D504C45 -unlock -mode clr
  

• Show APDU-s sent to the card:

  add -debug or -d to your command

• Be more verbose about decisions and conditions:

  add -verbose or -v to your command

• Don't use MAC on commands (plain GlobalPlatform syntax):

  add -mode clr to your command (not supported on all cards)

• Show all options recognized by gp utility:

  add -help or -h or --help to your gp command

• For now consult the command line utility source code
• Rudimentary Javadoc
• General rules:
  • Expect RuntimeException-s when things go unexpectedly wrong
  • CardException-s when link layer fails
  • GPException-s when protocol layer fails

• NEW! JavaCard Buyer's Guide of 2015
• See TestedCards
• Generally speaking any modern JavaCard that speaks GlobalPlatform 2.1.1+
• Available cards from all major vendors have been tested for basic compatibility: Athena, Gemalto, Giesecke & Devrient, Infineon, NXP (JCOP), Oberthur
  • If you are a smart card vendor please do get in touch for clarification and better support!

The ancestor of this code is GPJ (Global Platform for SmartCardIO) which is (still) available from http://gpj.sourceforge.net. I started the project because I felt that messing with cryptic script files was not nice and I wanted to have a simple, open source, usable and native-to-the-rest-of-development-environment (Java) toolchain.

The promise of OpenKMS is similar^* to OpenSSL:

Why buy a smart card software kit as a black box when you can get an open one for free?

In regard to GlobalPlatform, the goal is to make simple operations like installing and removing applets and locking the card with new keys as easy as next-next-done - you don't have to know the whole Global Platform specification by heart for that or buy a piece of proprietary software for a few hundred euros! For all those features that are not described in the GlobalPlatform specification that actually make your card work... you still have to use those proprietary commands, but OpenKMS GlobalPlatformPro toolkit's flexibility (and its license) should allow you to do that as well.

* _{With the difference that OpenKMS thrives for a easily usable and pleasantly readable, auditable and secure codebase. And yes, you have probably already sold your soul to the devil...}
