gpg: Switch to AES256 for symmetric encryption in de-vs mode.
* g10/gpg.c (set_compliance_option): For AES256 and SHA256 in de-vs
mode.
* g10/encrypt.c (setup_symkey): Add extra compliance check.
(encrypt_simple): Avoid printing a second error oncplinace failure.
--

Because we used the RFC4880 mode as base for the de-vs mode we got
3DES as symmetric encryption algorithm.  With the default gnupg mode
that was already used.  The new extra compliance checks are added to
detect whether a --personal-cipher-preference or --cipher-algo option
tried to override the algorithms.  They are still possible but now
non-compliant algorithms will throw an error.

Manual testing can be done with commands like this:

  gpg --no-options --compliance=de-vs \
   --personal-cipher-preferences "S1 S7" \
   --pinentry-mode loopback -v --passphrase abc -ac </etc/motd

Here the command fails due to IDEA (S1) being the preferred cipher
algorithm.  Using "--s2k-digest-algo SHA1" instead of
--personal-cipher-preferences will also fail.

gpg: Do not use weak digest algos if selected by recipient prefs.
* g10/misc.c (is_weak_digest): New.

* g10/sig-check.c (check_signature_end_simple): Use it.
* g10/sign.c (hash_for): Do not use recipient_digest_algo if it is in

--

If a message is signed and encrypted to several recipients, the to be
used digest algorithm is deduced from the preferences of the
recipient.  This is so that all recipients are able to check the the
signature.  However, if the sender has a declared an algorithm as
week, that algorithm shall not be used - in this case we fallback to
the standard way of selecting an algorithm.

Note that a smarter way of selecting the algo is to check this while
figuring out the algorithm - this needs more testing and thus we do it
the simple way.

--

In iobuf_read_line the parameter to pass and return the current buffer
length is controlled by the buffer parameter.  Thus there should be no
problem because the assert call check s buffer first.  For yet unknown
reasons when using the standard GNU libc assert valgrind complains
about an uninitialized variable.  That does not happen with our
log_assert.  Tested with gcc 8.3.0 and valgrind 3.14.0.

It is a bit surprising that nothing happens if no key is specified to

might have expected that it behaves like --export and deletes all

This patch allows to decrypt data encrypted using the new AEAD
mechanism as specified in rfc4880bis.  Although preferences are used
to enable this new mode, it is useful to have at least a decryption
option in case a user switches between GnuPG 2.2 and newer versions.

The new AEAD mechanism is much faster than the current CFB+MDC and
thus 2.2 will allow faster decryption of symmetric only decryption.

This patch is based on the current master (2.3) code base and includes
a few other patches.  In particular

gpg: Fix key expiration and usage for keys created at the Epoch.
* g10/getkey.c (merge_selfsigs_main): Take a zero key creation time in
account.
--

Keys created at the Epoch have a creation time of 0; when figuring out
the latest signature with properties to apply to a key the usual
comparison A > B does not work if A is always 0.  We now special case
this for the expiration and usage data.

This is is the second part to support the new Key Block subpacket.
The idea is that after having received a signed mail, it is instantly
possible to reply encrypted - without the need for any centralized
infrastructure.

There is one case where this does not work: A signed mail is received
using a specified signer ID (e.g. using gpg --sender option) and the
key block with only that user ID is thus imported.  The next time a
mail is received using the same key but with a different user ID; the
signatures checks out using the key imported the last time.  However,
the new user id is not imported.  Now when trying to reply to that
last mail, no key will be found.  We need to see whether we can update
a key in such a case.

This patch adds support for a to be proposed OpenPGP ferature:

  Introduce the Key Block subpacket to align OpenPGP with CMS.

  This new subpacket may be used similar to the CertificateSet of
  CMS (RFC-5652) and thus allows to start encrypted communication
  after having received a signed message.  In practice a stripped down
  version of the key should be including having only the key material
  and the self-signatures which are really useful and shall be used by
  the recipient to reply encrypted.

  #### Key Block

  (1 octet with value 0, N octets of key data)

  This subpacket MAY be used to convey key data along with a signature
  of class 0x00, 0x01, or 0x02.  It MUST contain the key used to create
  the signature; either as the primary key or as a subkey.  The key
  SHOULD contain a primary or subkey capable of encryption and the
  entire key must be a valid OpenPGP key including at least one User ID
  packet and the corresponding self-signatures.

  Implementations MUST ignore this subpacket if the first octet does not
  have a value of zero or if the key data does not represent a valid
  transferable public key.

--

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.

Bug is in 2.2.18 only.

The semantics of the enum_secret_keys function changed in master.
When back porting this for 2.2.18 I missed this change and thus we ran

We need to change the enum_secret_keys interface to avoid such a

* g10/options.h: Add flags.use_only_openpgp_card.
* g10/call-agent.c (start_agent): Implement option.
--

With the previous patch we switch to autoselect an application
instead of requesting an openpgp card.  This option allows to revert
this in case of use use cases which expected the former behaviour.

* g10/mainproc.c (check_sig_and_print): Print a hint on how to make

The use of the the keyid for lookups does not make much sense anymore
since for quite some time we do have the fingerprint as part of the
signature.

gpg: Add "self-sigs-only" and "import-clean" to the keyserver options.
* g10/gpg.c (main): Change default.
--

Due to the DoS attack on the keyeservers we do not anymore default to
import key signatures.  That makes the keyserver unsuable for getting
keys for the WoT but it still allows to retriev keys - even if that
takes long to download the large keyblocks.

To revert to the old behavior add

  keyserver-optiions  no-self-sigs-only,no-import-clean

to gpg.conf.

This change avoids error message like

  gpg: error retrieving 'foo@example.org' via None: No public key

A 'None' mechanism is something internal.

* g10/keylist.c (public_key_list): Add arg 'no_local'.

--

This new command is a shortcut for

  --auto-key-locate nodefault,clear,wkd,... --locate-key

and uses the default or configured AKL list but does so without local.

This option is intended to help against importing keys with many bogus
key-signatures.  It has obvious drawbacks and is not a bullet-proof
solution because a self-signature can also be faked and would be
detected only later.
