* g10/gpg.c (print_mds): Replace openpgp_md_test_algo.
--
This is actually not required because as of now the used OpenPGP and
Gcrypt hash algorithm numbers are identical. But that might change in
the future.
This changes the behavior of GnuPG in case it has been build with
some algorithms disabled: If those algorithms are available in
Libgcrypt, their results will be used printed anyway.
* g10/keyedit.c (subkey_expire_warning): New.
(keyedit_menu): Call it when needed.
--
GnuPG-bug-id: 1715
The heuristic to detect a problem is not very advanced but it should
catch the most common cases.
* agent/cache.c (last_stored_cache_key): New.
(agent_get_cache): Allow NULL for KEY.
(agent_store_cache_hit): New.
* agent/findkey.c (unprotect): Call new function and try to use the
last stored key.
* g10/revoke.c (create_revocation): Add arg CACHE_NONCE and pass to
make_keysig_packet.
(gen_standard_revoke): Add arg CACHE_NONCE and pass to
create_revocation.
* g10/keygen.c (do_generate_keypair): Call gen_standard_revoke with
cache nonce.
--
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).
* common/openpgpdefs.h (PUBKEY_ALGO_EDDSA): Change to 22.
* g10/keygen.c (ask_curve): Reword the Curve25519 warning note.
--
In the hope that the IETF will eventually assign 22 for EdDSA using
the draft-koch-eddsa-for-openpgp-01 specs we start using this number.
* dirmngr/ks-engine-hkp.c (cert_log_cb): Move to ...
* dirmngr/misc.c (cert_log_cb): here.
* dirmngr/ks-engine-http.c (ks_http_fetch): Support 307-redirection
and https.
--
Note that this requires that the root certificates are registered using
the --hkp-cacert option. Eventually we may introduce a separate
option to allow using different CAs for KS_FETCH and keyserver based
requests.
* common/http.c (http_session_ref): Allow for NULL arg.
--
We always test for a an existing session and thus passing NULL as
session object should be allowed.
Reported-by: Jens Lechtenboerger
* common/openpgp-oid.c (struct oidtable): New.
(openpgp_curve_to_oid): Rewrite and allow OID as input.
(openpgp_oid_to_curve): Make use of the new table.
--
Due to the previous change we now usually store the OID with the
private key and not the name. Thus during import we do not anymore
need to map the name to an oid but can use the oid directly. We fix
that by extending openpgp_curve_to_oid to allow an oidstr as input.
* agent/cvt-openpgp.c (get_keygrip): Special case EdDSA.
(convert_secret_key): Ditto.
(convert_transfer_key): Ditto.
(apply_protection): Handle opaque MPIs.
(do_unprotect): Check FLAG_OPAQUE instead of FLAG_USER1 before
unpacking an opaque mpi.
--
The key transfer protocol between gpg and gpg-agent uses gcrypt
algorithm numbers which merge all ECC algorithms into one. Thus it is
not possible to use the algorithm number to determine the EdDSA
algorithm. We need to known that because Libgcrypt requires the
"eddsa" flag with the curve "Ed25519" to actually use the Ed25519
signature specification.
The last fix is for correctness; the first case won't be used anyway.
* agent/protect.c (PROT_CIPHER): Rename to GCRY_CIPHER_AES128 for
clarity.
(do_decryption): Add args prot_cipher and prot_cipher_keylen. USe
them instead of the hardwired values.
(agent_unprotect): Change to use a table of protection algorithms.
Add AES-256 variant.
--
This patch will make a possible future key protection algorithm
changes smoother. AES-256 is also allowed although there is currently
no way to encrypt using it.
* g10/passphrase.c (passphrase_get): Replace sprintf by xasprintf.
--
Without that at least the French translation does not always work
because it requires positional parameters. Windows for example does
not support them as they are not defined by C99 but by POSIX.
* build-aux/getswdb.sh: New.
* build-aux/speedo.mk: Get release version numbers from swdb.lst.
--
This should make maintaining GnuPG installations easier. Running
make -f /foo/gnupg/build-aux/speedo.mk TARGETOS=native WHAT=release
downloads all GnuPG related packages and builds them. The gnupg
directory may be a GIT checkout but in that case please run
./autogen.sh on it first. Note that currently swdb.lst is always
downloaded from gnupg.org and thus monitoring the network or the gnupg
machine reveal information on who is currently building GnuPG. If
there is an easy way to detect that TOR is enabled this can be changed
to directly download from the GnuPG hidden service.
* kbx/keybox-blob.c (_keybox_create_openpgp_blob): Remove restriction.
--
Although self-signature and key binding signatures are required by
OpenPGP, we should not enforce that in the storage backend.
* g10/main.h (DEFAULT_CIPHER_ALGO): Chhange to AES or CAST5 or 3DES
depending on configure option.
* g10/gpg.c (main): Set opt.s2k_cipher_algo to DEFAULT_CIPHER_ALGO.
* doc/yat2m.c (variablelist): New.
(set_variable): New.
(macro_set_p): Also check the variables.
(proc_texi_cmd): Support the @value command.
(parse_file): Support the @set command.
(top_parse_file): Release variablelist.
* common/estream-printf.c, common/estream-printf.h: Change license.
* common/estream.c, common/estream.h: Ditto.
--
g10 Code is the sole copyright holder of Libestream and thus as CEO I
have the rights to to change the license. This copy here in GnuPG is
currently the most current one thus the change is recorded in this
repository. This change is also deemed valid for all older versions.

* sm/gpgsm.h (opt): Add field "no_homedir_creation".
* sm/gpgsm.c (main): Set it if --no-options is used.

g10/openfile.c.
(maybe_create_keybox): New. Similar to the one from g10/keydb.c.
(keydb_add_resource): Replace some code by maybe_create_keybox.
* g10/main.h (import_screener_t): New.
* g10/import.c (import): Add screener callbacks to param list.
(import_one): Ditto.
(import_secret_one): Ditto.
(import_keys_internal): Ditto.
(import_keys_stream): Ditto.
* g10/keyserver.c (struct ks_retrieval_screener_arg_s): New.
(keyserver_retrieval_screener): New.
(keyserver_get): Pass screener to import_keys_es_stream().

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.

This is an extended and fixed versions of Stefan's patch. In addition
to the changes done in gnupg 2.0, namely the commits

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.

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.
