This extends the long available OCB and EAX decryption feature. 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.
In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.

Note that this allows to create a new OpenPGP key from an initialized

with the TCOS Netkey card. Right now a stub file for the cards might
be needed; this can be achieved by running "gpgsm --learn" with the
card plugged in.

The problem here was that future-default gives the primary and subkey
algorithm. However, when using future-default for adding a key, the
second part was always used which is for encryption. If the caller
now wanted to create a signing subkey using the future-default
parameters this did not worked.
gpg --batch --passphrase "" --quick-add-key FPR future-default encr
aready worked as did
gpg --batch --passphrase "" --quick-add-key FPR ed25519 sign
but
gpg --batch --passphrase "" --quick-add-key FPR future-default sign
does only work with this fix.

* g10/keygen.c (keygen_set_std_prefs): when producing default internal
personal-digest-preferences, keep the same order. When publishing
external preferences, state preference for SHA512 first.
--
SHA-512 has a wider security margin than SHA-256. It is also slightly
faster on most of the architectures on which GnuPG runs today. New
keys should publish defaults that indicate we prefer the stronger,
more performant digest.
Specifically, this changes --default-preference-list from:
SHA256 SHA384 SHA512 SHA224
to:
SHA512 SHA384 SHA256 SHA224
This patch deliberately avoids touching --personal-digest-preferences
(which itself would affect the default of --digest-algo and
--cert-digest-algo), so that public-facing cleartext signatures and
identity certifications will continue to be made with SHA256 by
default.

* g10/keygen.c (generate_subkeypair): Ignore error code issued for

We try to verify the primary key and thus seed the passphrase cache
before generating the subkey. However, the verification does not yet
work for on-card keys and thus the PASSWD --verify send to the agent
returns an error. This patch detects this error and continues without
a seeded passphrase cache. After all that pre-seeding is just a
convenience.

At least the the extra leading space the left angle bracket is wrong.

just a plain mail address. Using just a mail address is anyway the
