There used to be a possible support of Ed25519 with ECDSA, (instead of
EdDSA). To distinguish key for Ed25519 for EdDSA, we use the
flag: (flags eddsa). Ed448 has no support for ECDSA and defaults to
EdDSA even if no such flag.

* scd/app-piv.c (app_select_piv): Allow for full AID.
--
It appears that SP-800-73-x is not too clear about the format of these
objects. Many current cards (such as the Yubikey 5 series) apparently
have only the PIX in DO 0x4F and only the RID in object 0x79/0x4F.
However, other cards as well as the PivApplet Javacard applet have the
full AID in 0x4F (which actually seems closer to what the standard
says). PivApplet also has the full AID in 0x79/0x4F, but this is
probably incorrect. (Here is a long discussion of the matter from an
OpenSC author:
https://github.com/arekinath/PivApplet/issues/43#issuecomment-772649709)

This patch gets us back to a unique serial number for cards and
provides a stable serial number as printed for Yubikeys.
Because we use a slightly different serial number now for Yubikeys and
cards only supporting OpenPGP card we need to come up with another
change so that the version number of OpenPGP serial numbers are
ignored when comparing card serial numbers. This is so that existing
stub keys of gpg-agent will continue to work.

this hack works on Windows, which has different implementation of

It's better to send the ESC command by the driver explicitly, at the

This can be used with gpg-card to write the 3 extra certificates of a
Telesec TCOS Signature Card v2. The card with the qualified signature
is distributed with the keys for encryption and advanced signatures
but without the certificates. The certificates can be downloaded from
the website after an mail confirmation. Unpacked the downloaded
zipfile has these certificates:
auth_zert.crt
sig_zert.crt
enc_zert.crt
Using gpg-card issue these commands:
writecert NKS-NKS3.4531 <sig_zert.crt
writecert NKS-NKS3.45B1 <enc_zert.crt
writecert NKS-NKS3.4571 <auth_zert.crt

There is no need to read the list of options from the components
unless they convey a default value. It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed. Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

has been done. Clearing the PIN cache is also not fully

Better safe than sorry.
We should also review the card reference counting to see whether we

This change will allow us to easier integrate an app swithcing logic.
The change should have no user visible effect. The error checking we
do now with the card locked will rarely be asserted. It is the
correct thing to do anyway.

In another patch we will need apptype_t in the ctrl object and thus we
need to reorganize things a bit now. Given that most files need
app-common anyway it makes sense to always include it.

Although quite large, this is a straightforward change to separate
card/token related data from card application related data. Before
this change there was a one-to-one relation between card and
application and no way to represent several applications on a card.
The new data structure will allow for such a representation.

instead of accessing the counter directly.
--
This is better in case we need to debug stuff. There is a real change
however: We now lock and unlock the app before changing the reference
count.
The whole app locking business should be reviewed because we pass
pointers along without immediately bumping the refcount.

in general never happen but if so we now return an error instead of
success.

There was the card-timeout option in GnuPG 2.0, but it was never
implemented correctly. The intention of this option was to allow
sharing smartcard among multiple applications, but this didn't work
well as user's expectation (it only worked with DISCONNECT command).
This is because other parts of scdaemon assumes exclusive access. In
GnuPG 2.1, the support of the option was removed, improving
"DISCONNECT" command always works well without this option.

This feature allows to quickly get the keygrip and in most cases also
the usage flags for one specific keyref. Example:

We already have $AUTHKEYID to locate the keyref of the key to be used
with ssh. It will also be useful to have default keyref for
encryption and signing. For example, this will allow us to repalce
the use of "OPENPGP.2" by a app type specific keyref.

Having the version of the yubikey is important to select which other

prefix. This does not affect app-openpgp becuase there we use the app
specific serial number.

This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.
