Here is how to list all subkeys expiring in the year 2061:

 gpg --list-keys --list-filter
      'select= sub/key_expires_d -gt 2061-01-01 \
               && sub/key_expires_d -lt 2061-12-31'

To list all primary key expirations, use the "pub/" prefix and to list
all expiration dates use no prefix.

--

If a key is searched by fingerprint or keyid and it happens that this
is an ADSK (subkey with the RENC usage), we need to skip this key
because it is not the key we actually want to encrypt to.  The actual
ADSK key is taken later by looking at all subkeys of the actual
selected key.

The problem showed up because in 2.4 we changed the standard ECDH
parameter some years ago.  Now when trying to write an ECDH key
created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong
fingerprint and thus gpg was not able to find the key again by
fingerprint.

The patch also avoids updating the stored fingerprint in certain
situations.

This fix is somewhat related to

If a Yubikey has been used in PIV mode the initial listing does not
look correct.  Although we explicitly switch to the OpenPGP app when
needed, we don't want to do this in listing mode.  Instead we offer a
new command "openpgp" to force the openpgp mode.  The ultimate goal
will be to enhance the gpg-card tool to completely take over the
--card-edit features.  But we are not yet there.

It may happen that the active card was last used for PIV and in that

Fortunately we have a pretty central place to assure that the right
app has been selected.

The bug can be easily noticed on Windows.

This used to work using the gpg-agent: learn we called at "save" time.

learn if a regular key still exists.  Now we do an explicit delete key
at save time.  This syncs the behaviour with the description of the

This makes use of a new encryption flag:

  automatic selection of encryption keys.  It is only found on a
  subkey signature (type 0x18), one that refers to the key the flag
  applies to.

gpg: New export option "mode1003".

(command_has_option): Ditto.
* g10/build-packet.c (do_key): Implement mode 1003.
* g10/parse-packet.c (parse_key): Ditto.

(secret_key_to_mode1003): New.
(receive_seckey_from_agent): Add arg mode1003.
(do_export_one_keyblock): Pass option down.
--

This option allows to export a secret key in GnuPG's native format.
Thus no re-encryption is required and further the public key parameters
are also authenticated if a protection passphrase has been used.

Note that --import is not yet able to handle this new mode.  Although
old version of GnuPG will bail out with "invalid packet" if a mode1003
exported secret key is seen.

* g10/import.c (impex_filter_getval): Add scope support and new
property names "key-size", "algostr", "origin", "lastupd", and "url".
--

This option is pretty useful to select keys based on their properties.
The scope thing can be sued to limit a selection to just the primary
key or to subkeys.  For example:

  gpg -k --list-filter 'select=revoked-f && sub/algostr=ed25519'

Lists all non-revoked keys with an ed25519 (signing)-subkey.

AEAD_ALGO_OCB.

parsing.
* g10/options.h (opt): Remove def_aead_algo and personal_aead_prefs.
--

Due to the meanwhile expired patent on OCB there is no more reason for
using EAX.  Thus we forcefully use OCB if the AEAD feature flag is set
on a key.

misplaced revocations.
(import_revoke_cert): Allow to pass an entire list.
(import_one): Import revocations found by delete_inv_parts.
--

It might be useful to distribute revocations of old keys along with
new keys.  This is in particicualrr useful for WKD stored keys.  This
patch allows to put unrelated standalone revocations into a key.  For
example they can simply appended to a keyblock.  Right now it is a bit
inaesthetic to see diagnostics about misplaced or bad revocation
signatures.

compiled with libgcrypt 1.11.0 can't work with older libgcrypt
runtime.

* g10/encrypt.c (encrypt_crypt): Use FILEFD directly.

--

Before 8402815d, original code was with iobuf_open_fd_or_name, which
used gnupg_fd_t for the file descriptor (FD2INT was relevant at that
time).  After the change, because it's not gnupg_fd_t but int, use of
FD2INT is irrelevant.

I have seen to many of these diagnostics and in particular the first
one seems to be a connected to the others.  Thus it does not make
sense to show them in standard verbose mode.

The ISO timestamp is much easier to read than than the localized
timestamp and switching from localtime to UTC should not harm.

The original check was too strong because it is in fact compliant to
encrypt with a symmetric key and and public key.  Thus decryption
should issue a compliance status.

In addition we now check that the cipher algorithms used to
symmetrically encrypt the session key are all compliant.  This is
similar to our check for all public key encrypted session key packets.

g10: Fix garbled status messages in NOTATION_DATA
* g10/cpr.c (write_status_text_and_buffer): Fix off-by-one
--

Depending on the escaping and line wrapping the computed remaining
buffer length could be wrong.  Fixed by always using a break to
terminate the escape detection loop.  Might have happened for all
status lines which may wrap.

This makes it possible to specify the user ID to revoke as UID hash when

gpg: Emit an ERROR status as hint for a bad passphrase.
* g10/mainproc.c (proc_symkey_enc): Issue new error code.
(proc_encrypted): Ditto.
--

This allows GPGME to return a better error message than "bad session
key" to the user.  Technically we could get run into these errors also
in other cases but this more unlikley.  For the command line use we
don't do anything to not change the expected output of the command
line interface.

* sm/gpgsm.c (main): Ditto.
* tools/gpg-connect-agent.c (main): Ditto.
* tools/gpgconf.c (main): Ditto.
(show_other_registry_entries): Print "DefaultLogFile".
--

The intention of this mostly forgotten registry entry was to allow for
easy debugging of the tools.  However, with the global config file
common.conf things are anyway better.  We disable the use for the
commonly used tools so that it does not look like calling gpg on the
command line seems to block with no output if the log
server (e.g. tcp://1.2.3.4:11111) is not reachable.

gpg: Remove restrictions for the name part of a user-id.
* g10/keygen.c (ask_user_id): Allow for the name to start with a
digit.  Allow names shorter than 5.
--

The reason for this change is that we don't enforce these constraints
in the --quick-gen-key interface.  I added the constraints right in the
beginning of gnupg to make sure that we have a uniform style for
user-ids.  However, this is all problematic with non-Latin names
and we prefer to use mail addresses anyway.

It is more than unlikely that EAX will ever be used in practice and

gpg: Print info about the used AEAD algorithm in the compliance msg.
* g10/misc.c (openpgp_cipher_algo_mode_name): New.
* g10/decrypt-data.c (decrypt_data): Use function here.
--

Note that openpgp_cipher_algo_mode_name is different from the version
2.2 becuase we append ".CFB" here.

Without this change we would see

  gpg: cipher algorithm 'AES256' may not be used in
  --compliance=de-vs mode

This is confusing because AES256 is compliant.  Now we see

  gpg: cipher algorithm 'AES256.OCB' may not be used in
  --compliance=de-vs mode

which gives a hint on the problem.

gpg: Allow decryption of symencr even for non-compliant cipher.
* g10/decrypt-data.c (decrypt_data): Add arg compliance_error.  Adjust
all callers.  Fail on compliance error only in --require-compliance
mode.  Make sure to return an error if the buffer is missing; actually
that should be an assert.
* g10/mainproc.c (proc_encrypted): Delay printing of the compliance
mode status.  Consult the compliance error now returned by
decrypt_data.
--

The actual case here is that we fail hard if a message has been AEAD
encrypted with one AEAD capable key and also with one passphrase.  In
general the preference system takes care of not using AEAD if one
recipient's key does not support it.  However, if the sender uses her
own AEAD-capable key _and_ a passphrase the message will be AEAD
encrypted.  This change allows to decrypt that anyway along with a
warning message.

Note that this does currently not work in 2.3 due to a non-compliant
libgcrypt.  We will however, backport this to 2.2.
