There are other smaller changes not described above.
This change tries to avoid new error messages so not to increase the
the number of translated strings or break too many existing
translations. It also tries to use existing strings and changes the
quoting to the most common style used in gpg.
Key specifications should in general use double quotes. Other values
should use single quotes. However. sometimes it is not easy to
distinguish between values given on the command line and key
specifications. According to old GNU coding standards diagnostics
should not start capitalized - whether this is a good idea is a
different thing but we used this rules for most strings. However,
strings which are used interactively should be properly capitalized
and end with a dot.

Signed-off-by: Neal H. Walfield <neal@g10code.com>
Reported-by: NIIBE Yutaka <gniibe@fsij.org>
A new feature (e8c53fc) turned up a bug whereby checking if a search
term matches multiple keys in the keyring causes the cache to be
inconsistent.
When we look for a key on the keyring, we iterate over each of the
keyblocks starting with the keyblock following the last result. For
each keyblock, we iterate over the public key and any subkeys. As we
iterate over each key, we first insert it into the cache and then
check if the key matches. If so, we are done.
In pseudo code:
for (i = last_result + 1; i < num_records; i ++)
keyblock = get_keyblock (i)
for (j = 1; j < len(keyblock); j ++)
key = keyblock[j]
update_cache (key)
if (compare (key, search_terms))
return ok
cache_filled = true
return ENOFOUND
When we look for the next match, we start with the following keyblock.
The result is that any subkeys following the key that matched are not
added to the cache (in other words, when a keyblock matches, the inner
loop did not necessarily complete and the subsequent search doesn't
resume it).
This patch includes a straightforward fix: only indicate the cache as
complete if we started the scan from the beginning of the keyring and
really didn't find anything.

Previously, only one weak digest rejection message was shown, of
whichever was the first type encountered. This meant that if "gpg
--weak-digest SHA224" encountered both an MD5 digest and a SHA224
digest, it would only show the user that the MD5 digest was rejected.
In order to let the user know which algorithms were rejected, we
needed to move the "shown" flag into a per-weak-algorithm location.
Given this additional complication, it made no sense to continue to
treat MD5 specially, so it is added as a default weak algorithm in the
same opt.weak_digests data structure as any other.

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.

The keybox code doesn't work directly with keyblocks. As such, the

Commit e0873a33 started tracking whether key ids where definitely in
the database. This information is, however, never used and thus just
unnecessarily inflates the cache. This patch effectively reverts that
change (however, e0873a33 contains two separate changes and this only
reverts that change).

proper error code. This change helps GPGME to return better error

What we do here is to keep track of key searches by long keyids (as

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.

Note that although PKA is now always build, it will only work if
support for looking up via DNS has not been disabled.
The new PKA only works with the IPGP DNS certtype and shall be used
only to retrieve the fingerprint and optional the key for the first
time. Due to the security problems with DNSSEC the former assumption
to validate the key using DNSSEC is not anymore justified. Instead an
additional layer (e.g. Trust-On-First-Use) needs to be implemented to
track change to the key. Having a solid way of getting a key matching
a mail address is however a must have.
More work needs to go into a redefinition of the --verify-options
pka-lookups and pka-trust-increase. The auto-key-locate mechanism
should also be able to continue key fetching with another methods once
the fingerprint has been retrieved with PKA.

Reported-by: Guilhem Moulin <guilhem@fripost.org>
Needed for unattended key edits with --status-fd, because since 2.1
status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
not fflush(3), so the standard output may not be flushed before each
prompt. (Which breaks scripts using select(2) to multiplex between
the standard and status outputs.)
His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed. This patch now
replaces most of them in g10/. At some places stdio is still used,
but that is local to a function and should not have side effects.

--
The keyring DB code did not reject packets which don't belong into a
keyring. If for example the keyblock contains a literal data packet
it is expected that the processing code stops at the data packet and
reads from the input stream which is referenced from the data packets.
Obviously the keyring processing code does not and cannot do that.
However, when exporting this messes up the IOBUF and leads to an
invalid read of sizeof (int).
We now skip all packets which are not allowed in a keyring.

Without that it is possible to force gpg to allocate large amounts of

Another way to mitigate would be to change the MPI read function to
allocate memory dynamically while reading the MPI. However, that
complicates and possibly slows down the code. A too large key packet
is in any case a sign for broken data and thus gpg should not use it.

This bug can't be exploited: Only if the announced length of the

Allowing to use the abbreviated form for detached signatures is a long
standing bug which has only been noticed by the public with the
release of 2.1.0. :-(
What we do is to remove the ability to check detached signature in
--batch using the one file abbreviated mode. This should exhibit
problems in scripts which use this insecure practice. We also print a
warning if a matching data file exists but was not considered because
the detached signature was actually a standard signature:
gpgv: Good signature from "Werner Koch (dist sig)"
gpgv: WARNING: not a detached signature; \
file 'gnupg-2.1.0.tar.bz2' was NOT verified!
We can only print a warning because it is possible that a standard
signature is indeed to be verified but by coincidence a file with a
matching name is stored alongside the standard signature.

use these old and broken keys. Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.
We have also kept support for v3 signatures until now. With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures. What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures. The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages. These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

We now cache the userids using the fingerprint. This allows to print

eventually start to retire the use of all the old keyid based
functions. However, at some places we only have the keyid and thus
some of them will need to be kept (maybe changed with an indication to
show that more than several user ids are matching).

This is a cherry-pick of 534e2876ac from
STABLE-BRANCH-1-4 against master
Some older implementations built and used RSA keys up to 16Kib, but
the larger secret keys now fail when used by more recent GnuPG, due to
secure memory limitations.
Building with ./configure --enable-large-secmem will make gpg
capable of working with those secret keys, as well as permitting the
use of a new gpg option --enable-large-rsa, which let gpg generate RSA
keys up to 8Kib when used with --batch --gen-key.

The problem was reported by dkg on gnupg-devel (2014-10-07):
I just discovered a new problem, though, which will affect people on
systems that have gpg and gpg2 coinstalled:
0) create a new keyring with gpg2, and use it exclusively with gpg2
for a while.
1) somehow (accidentally?) use gpg (1.4.x) again -- this creates
~/.gnupg/pubring.gpg
2) future runs of gpg2 now only look at pubring.gpg and ignore
pubring.kbx -- the keys you had accumulated in the keybox are no
longer listed in the output of gpg2 --list-keys
Note that gpgsm has always used pubring.kbx and thus this file might
already be there but without gpg ever inserted a key. The new flag in
the KBX header gives us an indication whether a KBX file has ever been
written by gpg >= 2.1. If that is the case we will use it instead of
the default pubring.gpg.

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.
The changeset here removes these unnecessary libraries from linking.
Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.
* g10/keyid.c (keygrip_from_pk): Use log_info and clear array on error.

This may happen due to algorithms or curves not supported by
Libgcrypt. We should only print a warning and not have gpg return

In gpg2, the following options are only relevant for scdaemon:
reader-port
ctapi-driver
pcsc-driver
disable-ccid
but in gpg1, they are options for gpg itself.
Some users of gpg1 might have these options in their
~/.gnupg/gpg.conf, which causes gpg2 to fail hard if it reads that
config file.
gpg2 should not fail hard, though giving a warning (and suggesting a
move to scdaemon.conf) seems OK.
This patch does *not* reintroduce any documentation for these options
in gpg.texi, even to indicate that they are "dummy" options, since
scdaemon.texi contains the appropriate documentation.

This is actually not required because as of now the used OpenPGP and

This patch adds two features:
1. The key for the last passphrase successfully used for unprotecting
a key is stored away. On a cache miss the stored away passphrase is
tried as well. This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase. See the
code for more comments.
2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt. Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

These changes introduces import functions that apply a constraining
filter to imported keys. These filters can verify the fingerprints of
the keys returned before importing them into the keyring, ensuring
that the keys fetched from the keyserver are in fact those selected by
the user beforehand.
