gpg: Print warning when rejecting weak digests
* g10/misc.c (print_md5_rejected_note): Rename to ..
(print_digest_rejected_note): this.  Parameterize function to take an

76afaed65e allowed extra --weak-digests,
but removed the one call to print_md5_rejected_note().  This replaces
and generalizes that warning.

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.

gpg: Fail decryption for AES etc message w/o MDC.
* g10/mainproc.c (proc_encrypted): Fail for modern messages w/o MDC.
--

This change turns the missing MDC warning into an error if the message
has been encrypted using a cipher with a non-64 bit block length cipher
and it is not Twofish.

We can assume that such messages are created by code which should have
been able to create MDC packets.  AES was introduced with 1.0.3 on
2000-09-18 shortly after MDC (1.0.2 on 2000-07-12).  We need to
exclude Twofish because that might have been used before MDC.

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
whether TOR mode is active so that we can print a hint to disable that
keyserver option.

user may still override that and thus we better check.

--
Signed-off-by: Neal H. Walfield <neal@g10code.com>.

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
user id packet, it can use the key id to look up the key block and
find the appropriate packet.

Calling exit from an exit handler is undefined behaviour.  It works on
Linux but other systems will hit an endless loop.  That is indeed
unfortunate but we can't do anything about it.  Calling _exit() would
be possible but that may lead to other problems.  Thus we change to
call a custom exit function :-(.

Using "make check verbose=1" is supported by tests/openpgp and thus
we add the same mechanism here.

--

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".

Change the function so that caller can select canonical name of curve

gpg: Do not return "Legacy Key" from lookup if a key is expired.
* g10/getkey.c (lookup): Map GPG_ERR_LEGACY_KEY.
--

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.

This also fixes a problem in the --with-colons mode.  Before this
patch the --with-colons output of --edit-key always showed pub/sub
regardless of the old toogle state.  Now it also prints sec/sbb.
