--
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.

We do not use this weirdo CREATE_UNICODE_ENVIRONMENT flag because it
does not make any sense to have non-ASCII names in the environment. I
can't imagine why this should be used at all and rationale for this

With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly. However, this seems to work only

PKA (Public Key Association) was a DNS based key discovery method
which looked up fingerprint by mail addresses in the DNS. This goes
back to the conference where DKIM was suggested to show that we
already had a better method for this available with PGP/MIME. PKA was
was later superseded by an experimental DANE method and is today not
anymore relevant. It is anyway doubtful whether PKA was ever widely
used.

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: 3ddd4410aef928827e1c8d4fb02c1ccd3f8eaea5
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.

For keys stored on NetKey cards or PIV cards we do not necessarily

is requested with the special algo "card" or, in case of the extended
unattended mode, with an algo like "card/sign".

This fixes a encrypt+sign case like: One recipient key has SHA512 as

curve. Because we don't want to use a truncated hash with ECDSA, we
need to have an exact match - this is in particular important for
smartcard which check that the hash matches the curves.

--
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
used digest algorithm is deduced from the preferences of the
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.
