OpenPGP-Card

Open source implementation of the OpenPGP smart card version 2.0 on a java card.

Card Requirements

Java card version 2.2.2 (2.2.1 might work but it is untested)
2048 bit RSA key support
Global platform 2.1.1 or above to use the loading scripts.

The applet was developed and tested on a JCOP 2.4.1 card (NXP J2A080).

Brief instructions

Make sure that the card reader is working.
The easiest way is to use GlobalPlatformPro to install the CAP file
The harder way is to use the GlobalPlatform tools
- Install the GlobalPlatform and gppcscconnectionplugin libraries from http://sourceforge.net/projects/globalplatform/files/GlobalPlatform%20Library/GlobalPlatform%20Library%206.0.0/
- Install GPShell from http://sourceforge.net/p/globalplatform/wiki/GPShell/
- Load the applet on the card

The actual parameters used to load the applet on the card depend on the card manufacturer, version and state. If using a JCOP 2.4.1 cards with test keys, the 'installJCOP41GPG.gpshell' script can be used:

gpshell installJCOP41GPG.gpshell

Warning! Too many failed authentications when trying to load the applet can lock the card and make it unusable.

Once the applet is initialized gpg / gpg2 can be used to initialize the card.
GnuPG 2.0.22 or above is recommended (older versions do not support importing RSA keys in the CRT format).

gpg2 --card-edit

The user PIN is '123456' and the admin PIN is '12345678' and it changing them is recommended.
