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.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X. This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.
In part two we will address the functions
mkdtemp
setenv
unsetenv
strpbrk
which may bot be implemented on all platforms. They are not required
on a libc based system.

v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
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.

This is a cherry-pick of 534e2876acc05f9f8d9b54c18511fe768d77dfb5 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

In gpg2, the following options are only relevant for scdaemon:
reader-port
ctapi-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

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

confirmation).

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.

This is an extended and fixed versions of Stefan's patch. In addition
to the changes done in gnupg 2.0, namely the commits
5e933008beffbeae7255ece02383606481f9c169
044847a0e2013a2833605c1a9f80cfa6ef353309
088f82c0b5e39687f70e44d3ab719854e808eeb6
the symbol names have been changed to "screener" to void mixing them
up with the iobuf filter feature and it has been changed to be used
with the dirmngr based keyserver lookup.

* g10/sig-check.c (do_check): Move some code to ...
* g10/misc.c (print_md5_rejected_note): new function.
* g10/mainproc.c (proc_tree, proc_plaintext): Enable MD5 workaround
only if option --allow-weak-digest-algos is used.
* g10/gpg.c (oRFC1991, oPGP2): Remove
(opts): Remove --pgp2 and --rfc1991.
* g10/options.h (CO_PGP2, CO_RFC1991): Remove. Remove all users.
(RFC2440, PGP2): Remove. Remove all code only enabled by these
conditions.
* tests/openpgp/clearsig.test: Remove --rfc1991 test.
--
The use of PGP 2.c is considered insecure for quite some time
now (e.g. due to the use of MD5). Thus we remove all support for
_creating_ PGP 2 compatible messages.
* g10/gpg.c (oCompressKeys, oCompressSigs): Remove.
(opts): Turn --compress-keys and --compress-signs in NOPs.
* g10/options.h (opt): Remove fields compress_keys and compress_sigs.
* g10/export.c (do_export): Remove compress_keys feature.
* g10/sign.c (sign_file): Remove compress_sigs feature.
--
These features are disabled in GnuPG since the very early days and
they fulfill no real purpose. For now we keep the command line
options as dummys.
* g10/gpg.c (aQuickKeygen): New.
* g10/misc.c (is_valid_user_id): New stub.
* g10/keygen.c (quickgen_set_para): New.
(quick_generate_keypair): New.
--
Note that the validation of the specified user id has not yet been
implemented.
* g10/parse-packet.c (parse_attribute): Avoid xmalloc failure and cap
size of packet.
--
Tavis Ormandy reported a fatal error for attribute packets with a zero
length payload. This is due to a check in Libgcrypt's xmalloc which
rejects a malloc(0) instead of silently allocating 1 byte. The fix is
obvious.
In addition we cap the size of attribute packets similar to what we do
with user id packets. OpenPGP keys are not the proper way to store
movies.
* common/iobuf.c (direct_open): Add arg MODE700.
(iobuf_create): Ditto.
* g10/openfile.c (open_outfile): Add arg RESTRICTEDPERM. Change call
callers to pass 0 for it.
* g10/revoke.c (gen_desig_revoke, gen_revoke): Here pass true for new
arg.
* g10/export.c (do_export): Pass true for new arg if SECRET is true.

* g10/keygen.c (gen_elg): Enforce keysize 1024 to 4096.
(gen_rsa): Enforce keysize 1024 to 4096.
(gen_dsa): Enforce keysize 768 to 3072.
--
It was possible to create 16k RSA keys in batch mode. In addition to the
silliness of such keys, they have the major drawback that under GnuPG
and Libgcrypt, with their limited amount of specially secured memory
areas, the use of such keys may lead to an "out of secure memory"
condition.
* agent/cvt-openpgp.c (convert_to_openpgp): Use the curve name instead
of the curve parameters.
* g10/export.c (canon_pubkey_algo): Rename to ...
(canon_pk_algo): this. Support ECC.
(transfer_format_to_openpgp): Expect curve name.
* g10/compress.c (do_uncompress): Limit the number of extra FF bytes.
--
A packet like (a3 01 5b ff) leads to an infinite loop. Using
--max-output won't help if it is a partial packet. This patch
actually fixes a regression introduced on 1999-05-31 (c34c6769).
Actually it would be sufficient to stuff just one extra 0xff byte.
Given that this problem popped up only after 15 years, I feel safer to
allow for a very few FF bytes.
Thanks to Olivier Levillain and Florian Maury for their detailed
report.
* g10/gpg.c: Add option --with-secret.
* g10/options.h (struct opt): Add field with_secret.
* g10/keylist.c (public_key_list): Pass opt.with_secret to list_all

the token string from the wrong field 14 to 15.

This option is useful for key managers which need to know whether a
key has a secret key. This change allows to collect this information
in one pass.
* g10/keyid.c (hash_public_key): Take care of NULL keys.
* g10/misc.c (pubkey_nbits): Ditto.
--
This problem was mainly due to our ECC code while checking for opaque
MPIs with the curve name.
* g10/parse-packet.c (mpi_read): Change error message on overflow.
--
This gets gpg 2.x in sync to what gpg 1.4 does. No need to die for a
broken MPI.

* g10/getkey.c (get_user_id): Do not call xmalloc with 0.
* common/xmalloc.c (xmalloc, xcalloc): Take extra precaution not to
pass 0 to the arguments.
--
The problem did not occur in 1.x because over there the xmalloc makes
sure to allocate at least one byte. With 2.x for most calls the
xmalloc of Libgcrypt is used and Libgcrypt returns an error insteead
of silent allocating a byte. Thus gpg 2.x bailed out with an
"Fatal: out of core while allocating 0 bytes".
The extra code in xmalloc.c is for more robustness for the other
xmalloc calls.
* kbx/keybox-search.c (keybox_search): Add arg R_DESCINDEX. Chnage
both callers.
* g10/keydb.c (keydb_search): Always set DESCINDEX.
--
This only affects the new keybox for OpenPGP keys in 2.1. The bug
exhibited itself by running GPA's backup command on Windows.
* g10/decrypt-data.c (decrypt_data): Do not distinguish between a bad
MDC packer header and a bad MDC.
--
The separate diagnostic was introduced for debugging a problems. For
explaining an MDC error a single error message is easier to
understand.
* g10/keygen.c (ask_expire_interval): Get the current time after the

(convert_transfer_key): Follow newer (>= 1.6) libgcrypt API, which
does not distinguish the detail.
(do_unprotect, convert_from_openpgp_main): Don't call
map_pk_openpgp_to_gcry, as it's the value of libgcrypt API already and
not the value defined by OpenPGP.

* g10/call-agent.c (check_hijacking): New.
(start_agent): Call it.
(membuf_data_cb, default_inq_cb): Move more to the top.
--
Note that GUIs may use the gpg status line

to detect this and print an appropriate warning.
* g10/photoid.c (show_photos): Set namehash.

(keyserver_get): Print data source diagnostic.
--
It has often been requested that the actually used IP of a keyservers
is shown in with gpg --recv-key and --search-key. This is helpful if

not make sense to create a trustdb if there is no need for it.

By modifying a keyserver or a DNS record to send a secret key, an
attacker could trick a user into signing using a different key and
user id. The trust model should protect against such rogue keys but
we better make sure that secret keys are never received from remote
sources.

For ECC it seems to be better to show the name of the curve and not
just the size of the prime field. The curve name does not anymore fit
into the "<size><letter>" descriptor (e.g. "2048R") and a fixed length
format does not work either. Thus the new format uses
"rsa2048" - RSA with 2048 bit
"elg1024" - Elgamal with 1024 bit
"ed25519" - ECC using the curve Ed25519.
"E_1.2.3.4" - ECC using the unsupported curve with OID "1.2.3.4".
unless --legacy-list-mode is given. In does not anymore line up
nicely in columns thus I expect further changes to this new format.

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones. This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.
This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA. As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF. Note that EdDSA (Ed25519)
does not yet work and that more changes are required.
The ECC support is still broken right now. Needs to be fixed.

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent. This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme. With many secret keys this is quite some
usability hurdle. In particular if a passphrase is not instantly
available.
To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used. For example:
gpg2 --batch --import mysecretkey.gpg
works without any user interaction due to the use of --batch. Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk. The next time,
the internal format of the key is used.
This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

This new features allows to use gpg without a Pinentry. As a
prerequisite the agent must be configured to allow the loopback
pinentry mode (option --allow-loopback-pinentry). For example
gpg2 --pinentry-mode=loopback FILE.gpg
may be used to decrypt FILE.gpg while entering the passphrase on the

--
Gpg uses the key database at several places without a central
coordination. This leads to several scans of the keybox for the same
key. To improve that we now use a simple cache to store a retrieved
keyblock in certain cases. In theory this caching could also be done
for old keyrings, but it is a bit more work and questionable whether
it is needed; the keybox scheme is anyway much faster than keyrings.
Using a keybox with 20000 384 bit ECDSA/ECHD keypairs and a 252 byte
sample text we get these values for encrypt and decrypt operations on
an Core i5 4*3.33Ghz system. The option --trust-model=always is used.
Times are given in milliseconds wall time.
| | enc | dec | dec,q |
|-----------+-----+-----+-------|
| key 1 | 48 | 96 | 70 |

| key 20000 | 69 | 106 | 88 |
| 10 keys | 540 | 290 | 70 |
The 10 keys test uses a mix of keys, the first one is used for
decryption but all keys are looked up so that information about are
printed. The last column gives decryption results w/o information
printing (--quiet).
The keybox is always scanned sequentially without using any index. By
adding an index to the keybox it will be possible to further reduce
the time required for keys stored to the end of the file.

Import and key listing does now work with the keybox format. It is

The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.

compatibility mode.

--
To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation). It does not make sense to suggest the use of this
old 64 bit blocksize algorithm. However, there is old data available
where it might be helpful to have IDEA available.

The problem is that Libgcrypt has no more support for the alternate
RSA ids and thus if asking for the number of parameters, they will
return zero. Now, this leads to packing the key parameters into an
opaque MPI but because the algorithm id is actually known to GPG, it
assumes valid RSA parameters.

This works by specifying the keygrip instead of an algorithm (section
number 13) and requires that the option -expert has been used. It
will be easy to extend this to the primary key.

Subject: [PATCH] avoid use of freed pointer
If we free pk2 at the top of the for-loop, set it to NULL
so that we don't free it again just before returning.
* revoke.c (gen_desig_revoke): Don't use pk2 after freeing it.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg. This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.
Note: the card key generation in gpg is currently broken. The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card. We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card. Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.
Returning -1 as an error code is not very clean given that gpg error
has more descriptive error codes. Thus we now return
GPG_ERR_NOT_FOUND for all search operations and adjusted all callers.
The protection used in the exported key used a different iteration
count than given in the S2K field. Thus all OpenPGP keys exported
from GnuPG 2.1-beta can't be imported again. Given that the actual
secret key material is kept in private-keys-v1.d/ the can be
re-exported with this fixed version.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
This helps in the case of an unknown key algorithm with a corrupted
packet which claims a longer packet length. This used to allocate the
announced packet length and then tried to fill it up without detecting
an EOF, thus taking quite some time. IT is easy to fix, thus we do
it. However, there are many other ways to force gpg to use large
amount of resources; thus as before it is strongly suggested that the
sysadm uses ulimit do assign suitable resource limits to the gpg
process. Suggested by Timo Schulz.
Without Libgcrypt 1.5 is was not possible to use ECC keys. ECC is
major new feature and thus it does not make sense to allow building
with an older Libgcrypt without supporting ECC.
Also fixed a few missing prototypes.
This was a regression in 2.1 introduced due to having the agent do the
signing in contrast to the old "SCD PKSIGN" command which accesses the
scdaemon directly and passed the hash algorithm. The hash algorithm
is used by app-openpgp.c only for a sanity check.
The import test imports the keys as needed and because they are
passphrase protected we now need a pinentry script to convey the
passphrase to gpg-agent.
The basic network code from http.c is used for finger. This keeps the
network related code at one place and we are able to use the somewhat
matured code form http.c. Unfortunately I had to enhance the http
code for more robustness and probably introduced new bugs.
Test this code using
gpg --fetch-key finger:wk@g10code.com
(I might be the last user of finger ;-)
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
DECRYPTION_INFO <mdc_method> <sym_algo>
Print information about the symmetric encryption algorithm and
the MDC method. This will be emitted even if the decryption
fails.
Wrote the ChangeLog 2011-01-13 entry for Andrey's orginal work modulo
the cleanups I did in the last week. Adjusted my own ChangeLog
entries to be consistent with that entry.
Nuked quite some trailing spaces; again sorry for that, I will better
take care of not saving them in the future. "git diff -b" is useful
to read the actual changes ;-).
The ECC-INTEGRATION-2-1 branch can be closed now.
Import and export of secret keys does now work. Encryption has been
fixed to be compatible with the sample messages.
This version tests for new Libgcrypt function and thus needs to be
build with a new Libgcrypt installed.
Quite some changes were needed but in the end we have less code than
before. Instead of trying to do everything with MPIs and pass them
back and forth between Libgcrypt and GnuPG, we know use the
S-expression based interface and make heavy use of our opaque MPI
feature.
Encryption, decryption, signing and verification work with
self-generared keys.
Import and export does not yet work; thus it was not possible to check
the test keys at https://sites.google.com/site/brainhub/pgpecckeys .
Changed order of some conditional to make to put the special case into
the true branch. Indentation changes. Minor other changes to make the
ECC code more similar to the rest of our code.
It builds but many sefltests still fail. Need to fix that before
using it with an ECDH enabled libgcrypt.

The following works:
gpg2 --gen-key (ECC)
gpg2 --list-keys
gpg2 --list-packets ~/.gnupg/pubring.gpg
gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>
ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.
overflow when picking an algorithm (not a security issue since we
can't pick something not present in all preference lists, but we might
pick something that isn't scored first choice).
* pkclist.c (select_algo_from_prefs): Slightly improve the handling of
MD5 in preference lists. Instead of replacing MD5 with SHA-1, just
remove MD5 from the list altogether, and let the next-highest ranked
algorithm be chosen.
