gpg: New option --default-new-key-algo.
* common/openpgp-oid.c (openpgp_is_curve_supported): Add optional arg
R_ALGO and change all callers.
* common/util.h (GPG_ERR_UNKNOWN_FLAG): New error code.
* g10/options.h (struct opt): Add field DEF_NEW_KEY_ALGO.
* g10/gpg.c (oDefaultNewKeyAlgo): New enum.
(opts): New option "--default-new-key-algo".
(main): Set the option.
* g10/keygen.c: Remove DEFAULT_STD_ FUTURE_STD_ constants and replace
them by ...
(DEFAULT_STD_KEY_PARAM, FUTURE_STD_KEY_PARAM): new string constants.
(get_keysize_range): Remove arg R_DEF and return that value instead.
Change all callers.
(gen_rsa): Use get_keysize_range instead of the removed
DEFAULT_STD_KEYSIZE.
(parse_key_parameter_part): New function.
(parse_key_parameter_string): New function.
(quick_generate_keypair): Refactor using parse_key_parameter_string.
(generate_keypair): Ditto.
(parse_algo_usage_expire): Ditto.

This new option is intended to be used in the forthcoming
--set-profile command of gpgconf.  It allows to provide a gpg
configuration with custom defaults for a new key using the simple
commands which use the default algorithm set.

Now, sdcaemon answer for KEY-ATTR is in the canonical curve name
instead of the alias.  Since it is used of key generation for
card encryption key with backup, it should be canonical name.

NIIBE Yutaka 980c037bed g10: smartcard keygen change.
* g10/call-agent.c (scd_genkey_cb_append_savedbytes): Remove.
(scd_genkey_cb): Only handle KEY-CREATED-AT and PROGRESS.
(agent_scd_genkey): Remove INFO argument.  CREATETIME is now in/out
argument.
(agent_readkey): Use READKEY --card instead of SCD READKEY.
* g10/keygen.c (gen_card_key): Use READKEY --card command of the agent
to retrieve public key information from card and let the agent make
a file for private key with shadow info.
--

This change removes gpg's KEY-DATA handling for SCD GENKEY.  Information
with KEY-DATA is simply not used.  Instead, it is read by READKEY --card
command of gpg-agent.  This can consolidate public key handling in a
single method by READKEY.

The --openpgp flag for gpg-agent's EXPORT_KEY actually forces
encryption in a certain (RFC 4880-compatible format).  This changeset
exposes that functionality in internal functions, and clarifies
functionality in the agent's help text.

--

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent.  This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme.  With many secret keys this is quite some
usability hurdle.  In particular if a passphrase is not instantly
available.

To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used.  For example:

   gpg2 --batch --import mysecretkey.gpg

works without any user interaction due to the use of --batch.  Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk.  The next time,
the internal format of the key is used.

This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

This new features allows to use gpg without a Pinentry.  As a
prerequisite the agent must be configured to allow the loopback
pinentry mode (option --allow-loopback-pinentry).  For example

  gpg2 --pinentry-mode=loopback FILE.gpg

may be used to decrypt FILE.gpg while entering the passphrase on the
tty.  If batch is used, --passphrase et al. may be used, if
--command-fd is used, the passphrase may be provided by another
process.  Note that there are no try-again prompts in case of a bad
passphrase.

Werner Koch 096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.

Werner Koch 37228cfa05 Allow generation of card keys up to 4096 bit.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg.  This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.

Note: the card key generation in gpg is currently broken.  The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card.  We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card.  Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.

Werner Koch 1c09def22d Fix usage of SHA-2 algorithm with OpenPGP cards.
This was a regression in 2.1 introduced due to having the agent do the
signing in contrast to the old "SCD PKSIGN" command which accesses the
scdaemon directly and passed the hash algorithm.  The hash algorithm
is used by app-openpgp.c only for a sanity check.
