f1cf799a37 scd: Better handling of timeout and time extension.
* scd/ccid-driver.c (CCID_CMD_TIMEOUT_LONGER): Remove.
(ccid_transceive): Don't use x4 blindly for bBWI, but use dynamically
determined value.  Use value from variable wait_more for bulk_in.
Set wait_more by the value of time extension request.

gpg: Improve the code to decrypt using PIV cards.
* g10/call-agent.c (agent_scd_keypairinfo): Add arg 'keyref'.
* g10/keygen.c (ask_algo): Adjust.
* g10/skclist.c (enum_secret_keys): Request the keyref directly.
--

This improves commit ec6a677923 to avoid
looping over all keypairinfos.  This way scdaemon does not need to
compute all the keypairinfos for all keys of a card.  This patch is
possible due the enhanced READKEY command in scdaemon.

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

 <- readkey --info-only  PIV.9D
 -> S KEYPAIRINFO FC6061FB457224370B85C6F34DD56CD29E669620 PIV.9D e

We already have $AUTHKEYID to locate the keyref of the key to be used

encryption and signing.  For example, this will allow us to repalce
the use of "OPENPGP.2" by a app type specific keyref.

--

The old algorithm limited the length of a bucket chain by purging the
last 50% or the entries.  Thus the first domains entered into the
cache were never purged.  The new algorithm is a bit better: It also
limits the chain length on overflow to 50% but tries to keep the
entries indicating that a WKD is available in the cache.  If there is
still space to keep more, those which clearly do not support WKD are
also kept.

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

The PGP desktops exported secret keys are really stupid.  And they

out (section 11.2):

  [...]  Implementations SHOULD include self-signatures on any user
  IDs and subkeys, as this allows for a complete public key to be
  automatically extracted from the transferable secret key.
  Implementations MAY choose to omit the self-signatures, especially
  if a transferable public key accompanies the transferable secret
  key.

Now if they would only put the public key before the secret
key. Anyway we now have a workaround for that ugliness.

When importing an invalid secret key ring for example without key
binding signatures or no UIDs, gpg used to let gpg-agent store the
secret keys anyway.  This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key.  After importing
the public key the secret keys suddenly showed up.

This changes the behaviour of

This prepares the support for OpenPGP v5 keys.  The new version 2 blob
format is needed for the longer fingerprints and we also use this
opportunity to prepare for storing the keygrip in the blob for faster
lookup by keygrip.  Right now this is not yet functional.

Avoiding CIPHER_ALGO_AES192 is intentional here.

common: Minor rework of tty_get.
* common/ttyio.c (do_get): Re-indent and remove the checking for char
values larger than 0xa0.  Use explicy control character checking.
--

The code is really old (mid 1998) and with the checking for 0xa0 it
has an implicit assumption of utf-8 or latin-1.  Worse, the check was
for c > 0xa0 and not c == 0xa0 so it never worked as intended.
