Open Message to Werner Koch:
The OpenPGP Smartcard page says a FAQ is in production. While I'm pretty
sure you can come up with enough questions, I pose the following questions
which have occurred to me, and in the cases where I was able to make a
decent sounding response, I have included an answer. Please feel free to use
these in the FAQ.
Also I encourage others to post questions they have (or have had).
Q: What cards does GPG support?
A: GPG supports any card that Implements the OpenPGP Card spec. The only
current implementation is available from Kernel concepts.
TECH NOTE: If you implement the spec in the form of software for an already
existing card, please consider sharing it. In such an event you must apply
for a free manufacture ID from FSF Europe e.V., also ensure that there is
some mechanism by which each card can have a different serial number.
Q: What card readers can GPG use?
Q: Can I use algorithms other than RSA?
A: The OpenPGP spec currently allows only RSA keys; however, it was created
to allow other key types to be added later.
Q: Can I use RSA keys larger than 1024 bits?
A: The spec allows for keys of 1024 bits or larger. The current card only
supports 1024 bit keys.
Q: If the card locks up from invalid pins can it be unlocked?
