gpg and gpgv treat signatures made over MD5 as unreliable, unless the
user supplies --allow-weak-digests to gpg. Signatures over any other
digest are considered acceptable.
Despite SHA-1 being a mandatory-to-implement digest algorithm in RFC
4880, the collision-resistance of SHA-1 is weaker than anyone would
like it to be.
Some operators of high-value targets that depend on OpenPGP signatures
may wish to require their signers to use a stronger digest algorithm
than SHA1, even if the OpenPGP ecosystem at large cannot deprecate
SHA1 entirely today.
This changeset adds a new "--weak-digest DIGEST" option for both gpg
and gpgv, which makes it straightforward for anyone to treat any
signature or certification made over the specified digest as
unreliable.
This option can be supplied multiple times if the operator wishes to
deprecate multiple digest algorithms, and will be ignored completely
if the operator supplies --allow-weak-digests (as before).
MD5 is still always considered weak, regardless of any further
--weak-digest options supplied.

It is in general a bad idea to use honor-keyserver-url but if Dirmngr

Dirmngr know about the use of this option and let Dirmngr tell use

A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.

The keybox code doesn't work directly with keyblocks. As such, the
matched user packet is not readily available to pass to
DESC[n].SKIPFNC. But, we do know the index of the user id packet that
matched. Thus, pass that instead. If the skip function needs the

Due to the new keyalgo/size format the UID was not anymore printed
properly aligned to the creation date. Although we can't do that in
any case, this change does it for common algos like "rsa2048",
"dsa2048", and "ed25519".

If an expired key is directly followed by a legacy key in the keyring,
the lookup function incorrectly returned "legacy key" instead of
"unusable key". We fix it by handling not found identical to a legacy
key if the last finish lookup failed.

What we do here is to keep track of key searches by long keyids (as
stored in all signatures) so that we do not need to scan the keybox
again after we already found that this keyid will result in
not-found. As soon as we change gpg to run as a co-process we should
store this table per session because other instances of gpg may have
updated the keybox without us knowing.
On a test ring with
gpg: 94721 good signatures
gpg: 6831 bad signatures
gpg: 150703 signatures not checked due to missing keys
gpg: 5 signatures not checked due to errors
gpg: keydb: kid_not_found_table: total: 14132
this new cache speeds a --check-sigs listing up from 28 minutes to
less than 3 minutes.
