Fixes bug#1355.
|
|
|
|
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.

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.
|
|
See ChangeLog for details. Key generation, signing and verification works.
Encryption does not yet work. Requires latest Libgcrypt changes.
|
|
Also nuked some trailing spaces.
|
|
Signing and verification using a new key works again.
|
|
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.

* configure.ac: Need Libgcrypt 1.4.6 due to AESWRAP.
(HAVE_GCRY_PK_ECDH): Add new test.

* cvt-openpgp.c (GCRY_PK_ECDH) [!HAVE_GCRY_PK_ECDH]: New.
[include/]
2011-01-21 Werner Koch <[email protected]>
* cipher.h (GCRY_PK_USAGE_CERT): Remove compatibility macros
because we now require libgcrypt 1.4.6.
(GCRY_PK_ECDH): Add replacement.

ECDSA.

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.
|
|
Check vor v1 card while signing.
|
|
A couple of forward ported changes.
Doc updates.
|
|
It builds fine and passes some of the tests but there are quite some
features which don't work yet.
|
|
stdio.
|
|
The code won't get confused anymore by extra packages following the
encrypted one.
|
|
|
|
|
|
Still one problem left; marked with a gcc #warning.
|
|
|
|
Fix zero length MPI reading.
|
|
Add some not yet code to app-nks.c
Changed batch mode expiration time computation
|
|
|
|
|
|
W32 gettext changes.
Comment and typo fixes.
|
|
Change default keyserver.
Allow key protection with Camellia.
|
|
Support Camellia for testing.
More audit stuff.
|
|
Removed intl/.
|

contains 'P', 'G', 'P', and nothing but. (parse): Call it here.
(skip_packet): No longer need to handle marker packets here.
|
|
* parse-packet.c (parse_signature): It's hex.
* getkey.c (merge_selfsigs_subkey): Avoid listing the contents of a
backsig when list mode is on. Noted by Timo Schulz.
|
|
|
|
reading even for corrupted packets.
* keygen.c (generate_user_id): Need to allocate one byte more.
Reported by Felix von Leitner.
|
|
|
|
packed s2k iteration count.
* main.h, options.h, gpg.c (encode_s2k_iterations, main), passphrase.c
(hash_passphrase): Add --s2k-count option to specify the number of s2k
hash iterations.

This prevents a memory allocation attack with a very large user ID. A
very large packet length could even cause the allocation (a u32) to wrap
around to a small number. Noted by Evgeny Legerov on full-disclosure.
|
|
(build_sig_subpkt_from_sig), getkey.c (fixup_uidnode,
merge_selfsigs_main, merge_selfsigs_subkey), keygen.c
(keygen_add_key_expire): Fix meaning of key expiration and sig
expiration subpackets - zero means "never expire" according to 2440,
not "expire instantly".
|
|
Still does not build.
|
|
The gpg part does not yet build.
|

cleaning from one convenient place.
* options.h, import.c (parse_import_options, clean_sigs_from_all_uids,
import_one): Reduce clean options to two: clean and minimize.
* parse-packet.c (setup_user_id): Remove. (parse_user_id,
parse_attribute): Just use xmalloc_clear instead.
|
|
parse_attribute_subpkts): Make a number of warnings verbose items.
These fire on many slightly mangled keys in the field, so the
warning is becoming burdensome.
|
|

|
|
about missing timestamp or keyid. In case we don't use that key
there won't be no further error and thus gpg does not need to
return with an error.

selfsig into both the pk and sk, so that someone importing their sk (which
will get an autoconvert to the pk) won't end up with two selfsigs.
(do_generate_keypair): Call it from here.
* parse-packet.c (can_handle_critical_notation): New. Check for
particular notation tags that we will accept when critical. Currently,
that's only [email protected], since we know how to handle
it (pass it through to a mail program). (can_handle_critical): Call it
from here. (parse_one_sig_subpkt): Sanity check that notations are
well-formed in that the internal lengths add up to the size of the
subpacket.
