Problem installing OpenPGP applet onto A22CR card

Post by tay00000 » Tue Sep 27, 2016 11:29 pm

Hi,

I recently received the latest batch of A22CR cards I purchased and I am unable to install the OpenPGP applet from the "OpenPGPApplet Instructions & Applet Source Code" post.

I am getting the SW: 6985 whenever I attempt to install them on my latest batch of A22CR cards.

Any help would be much appreciated.

Did you debug your applet using JCIDE, it has the simulator of A22CR card?
You can debug with A22CR simulator and find out where the exception raised.

A new update on the situation.

I have retried to download again and now it manages to be loaded. Either the previous download was problematic or a wrong CAP file was loaded.

Manage to load OpenPGP applet with latest A22CR successfully.

Here's my finding on the compatibility on the many versions of OpenPGP applet.

Yubico's OpenPGP is incompatible with A22CR due to it's buffer using too much RAM memory.

Latest version of Javacard-OpenPGP (original author of the javacardopenpgp applet) is incompatible with A22CR as well due to RAM memory use increased in the latest versions.

Only the OpenPGP applet from "OpenPGPApplet Instructions & Applet Source Code" post works for now on the A22CR.

Anyone wanting to use OpenPGP applet should stick to the one found on this forum for stability purposes.

Yup. It's working now. Maybe I mixed up all the different variants openpgpapplet while in an attempt to debug and install one out of the many versions for my own use.
