--

Key generation direct from the card used to work for all cards except
the OpenPGP cards. The key generation from card using an OpenPGP card
is special because the fingerprint is stored on the card and we must
make sure that the newly created key has the same fingerprint.  This
requires that we take the key creation date as stored on the card into
account.

Along with the recent change in gpg-agent this change also fixes a
problem with existing stub files.

Note that with a key take from a card the self-signature are created
with the current time and not the creation time.  This allows to
better distinguish keys created using the same card.

This allows to first create keys on the card (e.g. using gpg-card)
even without having any public key for OpenPGP.  Then the key
generation option 14 (cardkey) can be used to create a primary OpenPGP
key from the key on the card.

There are still a couple of problems related to the agent which
creates the stub key and may run into problems if creating a second
key from the card.  This will be fixed in a future patch.

This does now allows to create a single OpenPGP key optioanlly with a

Using option --force will overwrite and already existing key.
scdaemon does here take care of swicthing the key attributes before
generating the key.

TODO: We need to add some more stuff to app-openpgp so that the user
is not annoyed by beeing asked to enter the Admin-PIN twice (change
the key attributes clear the verification state).  gpg's key
generation also needs some tweaks for using an existing card key which
has no key stub in private-keys-v1.d.

--

It seems to be possible to play tricks with packet structures so that
log_error is not used for a bad input data.  By actually checking the
return code and let the main driver in gpg call log_error, we can fix
this case.

Note that using gpg --verify-files and relying solely on gpg's return
code is at best a questionable strategy.  It is for example impossible
to tell which data has been signed.

This function is intended as a more general version of gpg's

uses static table of algorithm strings instead.  There should be only
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all

card: Allow switching of cards and applications.
* tools/card-call-scd.c (struct card_cardlist_parm_s): Add field
with_apps.
(card_cardlist_cb): Handle the new with_apps flag.
(scd_switchcard): New.
(scd_switchapp): New.
(scd_applist): New.
(scd_serialno): Pass --all also in --demand mode.

* tools/gpg-card.c (cmd_list): Simplify switching of cards.  Add
switching of alls.  Print a list of apps per card.
--

Note that the output format of "list --card" slightly changes: The
current card is indicated with an asterisk.  That should not harm any
robust parsers which might already be in use.  It is anyway a
development version.

These new commands allow to switch between known cards and are in
particular useful for the gpg-card tool.

gpg: Print better debug info in case of broken sig subpackets.
* g10/parse-packet.c (enum_sig_subpkt): Print a hexdump.
--

A test key for this is 02DF08F5FD356BF27F5F7B838921B5DCCD15A883 .
A key listing in verbose mode will now yield

  gpg: DBG: buffer shorter than subpacket (10/9/25);\
       dump: 19100d87e54973647cff

The error here is that the packet length is 0x19 but what follows is a
long keyid (subpacket 16) which is shorter.  The debug output might be
helpful to better analyze broken signatures.

8edd4b8b8c gpg: Use "SCD KEYINFO" to get available card keys.
* g10/skclist.c (enum_secret_keys): Don't use agent_scd_cardlist and
agent_scd_serialno, but agent_scd_keyinfo.

--

When there are multiple cards/tokens, this change can avoid switching
card of foreground access.
