AID weirdness on J3R180 #51

Closed 65a closed 1 year ago

65a commented 1 year ago

Card is J3R180. Close this bug if I somehow mangled my custom AID.

If I use the default AID, I can generate keys and use the card as expected.

If I use (I believe) a formally valid random AID such as D276000124010304FFD6EB4A3E2600, any attempt to generate keys results in an error: gpg: error checking the PIN: Invalid ID

scdaemon trace of this failure condition (with a different random AID) looks like:

Indeed, my custom AID is mangled. RFU section is 2 bytes, but 4 zeros.
