“Hardware problem” with OpenPGP smart card

[Nicolas Boullis]

Hi,

I’ve been using GnuPG with my private keys stored in an OpenPGP 
smartcard since year 2014. Suddenly, it stopped working yesterday.

The smartcard is an ID000-cut version 2 OpenPGP smartcard, that I put 
in a Gemalto Shell Token v2 card reader.

Whenever I try to decrypt a file with gnupg, it asks me for the pin 
code, and then fails with:

gpg: public key decryption failed: Hardware problem
gpg: decryption failed: No secret key

But gpg2 --card-status looks fine:

Has anyone experienced such a problem?
Any suggestion how I can sort this out?


Cheers,
