(release_list): Free that list.
(proc_symkey_enc): Record infos from symmetric session packet.
(proc_encrypted): Check symkey packet algos
--
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/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.

nodes of the keyblock.
* tests/openpgp/quick-key-manipulation.scm: Add test for revoking a

This makes it possible to specify the user ID to revoke as UID hash when
calling --quick-revoke-uid.
GnuPG-bug-id: 5936
* 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.
GnuPG-bug-id: 5943
* g10/keyedit.c (menu_adduid): Move linefeed character to the format
string.
--
This fixes a literal '\n' in the error message and a missing line feed
after the error message.

* 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.
* 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.
* g10/gpg.c (main): Remove note about rfc4880bis.
* g10/keygen.c (keygen_set_std_prefs): Use only OCB in the AEAD
preference list.
--
It is more than unlikely that EAX will ever be used in practice and
thus we remove it from the preference list.
* 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.
* 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.
* g10/sign.c (sign_symencrypt_file): Insert correct version and AEAD
information into symkey packet.

Remove "(src_len == 0)" check in filter_flush which was

flush problem in compress filters.

When encrypting with AES256.OCB on AMD Ryzen 5800X, memcpy shows as

There is one important use case for this: For systems configured
globally to use de-vs mode, Ed25519 and other key types are not
allowed because they are not listred in the BSI algorithm catalog.
Now, our release signing keys happen to be Ed25519 and thus we need to
offer a way for users to check new versions even if the system is in
de-vs mode. This does on purpose not work in --batch mode so that
scripted solutions won't accidently pass a signature check.

Note that --use-keybox still works but prints a warning. We will
eventually remove this option becuase it was marked as an experimental
feature anyway.
It would be too confusing if gpg and gpgsm use different key storages.
Further, other components (e.g. dirmngr or gpg-wks-client) which call
gpg or gpgsm need to be aware that the keyboxd is used and pass that
option on the command line. Now that common.conf is always read (even
if --no-options is used) those tools will work instantly.

--
This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.
This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf. Other
configured keyservers are ignored.
Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key. This is currently supported for OpenPGP
cards and certain PKCS#15 cards.

(keyedit_menu): Implement.
--
The plumbing is done in two parts: the agent is modified to understand
a KEYTOTPM assuan command taking the key grip as an argument. This
simply obtains the key s expression and calls the existing writeky
diversion to the tpm2daemon. The daemon reponds with the TPM
conversion of the key and that key is then stored in the keyfile as a
shadowed-private-key with "tpm2-v1" type.
To effect the conversion, all the user does from gpg --edit-key is
select which private key they wish to move (or move the primary if no
key is selected) and type keytotpm. The conversion to TPM form is
instantaneous and once converted, the actual key cannot be recovered,
meaning that if you want your gpg key to move to a new laptop you must
keep an unconverted backup copy in a safe location.
When you do a list command, all TPM keys show up as
card-no: TPM-Protected
The key is stored encrypted to the TPM2 storage seed and since each
TPM has a unique seed, only the single TPM contained in your laptop
can now read the key. This means you cannot simply copy the shadowed
key file over to a new laptop, you must copy over the backup copy and
then convert it to TPM form on the new laptop.
To decomission your laptop, execute a tssclear command which
regenerates the storage seed and effectively shreds all keys. Note
when you have done this *every* TPM2 shadowed private key becomes
unreadable by any TPM and all are effectively destroyed.

The pgpSignerID has no use in the LDAP and thus don't store it.
David's idea back in 2004 was
/* This bit is really for the benefit of people who
store their keys in LDAP servers. It makes it easy
to do queries for things like "all keys signed by
Isabella". */
See-commit: 3ddd4410ae
I consider this dangerous because such a query is not able to validate
the signature, does not get revocation signatures, and also has no
information about the validity of the signatures. Further many keys
are spammed tehse days with faked signatures and it does not make
sense to blow up the LDAP with such garbage.

--
Because we used the RFC4880 mode as base for the de-vs mode we got
3DES as symmetric encryption algorithm. With the default gnupg mode
that was already used. The new extra compliance checks are added to
detect whether a --personal-cipher-preference or --cipher-algo option
tried to override the algorithms. They are still possible but now
non-compliant algorithms will throw an error.
Manual testing can be done with commands like this:
gpg --no-options --compliance=de-vs \
--personal-cipher-preferences "S1 S7" \
--pinentry-mode loopback -v --passphrase abc -ac </etc/motd
Here the command fails due to IDEA (S1) being the preferred cipher
algorithm. Using "--s2k-digest-algo SHA1" instead of
--personal-cipher-preferences will also fail.

If a message is signed and encrypted to several recipients, the to be

recipient. This is so that all recipients are able to check the the
signature. However, if the sender has a declared an algorithm as
week, that algorithm shall not be used - in this case we fallback to
the standard way of selecting an algorithm.
Note that a smarter way of selecting the algo is to check this while
figuring out the algorithm - this needs more testing and thus we do it
the simple way.
