* scd/app-openpgp.c (do_sign): Only prepend message digest block
for RSA or do_auth.
(do_auth): Remove message digest block for ECDSA.
--
If we don't need to check the message digest block by SCDaemon, we
don't requite the message digest block for ECDSA by gpg-agent.
* scd/app-openpgp.c (key_type_t): New.
(CURVE_NIST_P256, CURVE_NIST_P384, CURVE_NIST_P521): New.
(struct app_local_s): Change keyattr to have key_type and union.
(get_ecc_key_parameters, get_curve_name): New.
(send_key_attr, get_public_key): Support ECDSA.
(build_privkey_template, do_writekey, do_genkey): Follow the change
of the member KEY_ATTR.
(parse_historical): New.
(parse_algorithm_attribute): Support ECDSA.
--
Add ECDSA support to OpenPGP card.
* g10/keygen.c (append_to_parameter): New.
(proc_parameter_file): Use new func to extend the parameter list.
* g10/passphrase.c (passphrase_to_dek_ext): Print a diagnostic of
gcry_kdf_derive failed.
* g10/keygen.c (proc_parameter_file): Print a diagnostic if
passphrase_to_dek failed.
--
Due to an improper way of using the linked list head, all memory for
items allocated in proc_parameter_file was never released. If batched
key generation with a passphrase and more than ~200 keys was used this
exhausted the secure memory.
* configure.ac [freebsd]: Do not add /usr/local to CPPFLAGS and
LDFLAGS.
--
Back in ~2000 we introduced a quick hack to make building of Libgcrypt
on FreeBSD easier by always adding -I/usr/local/include and
-L/usr/local/lib . It turned out that this is a bad idea if one wants
to build with library version which is not installed in /usr/local.
The hack made was eventually (in 2003) copied from Libgcrypt to
GnuPG-2.
* agent/command.c (cmd_keytocard): Decrement KEYDATALEN.
* agent/findkey.c (agent_public_key_from_file): Increment for ELEMS.
--
For ECDSA and ECDH, there are 6 elements.
* g10/keygen.c (append_to_parameter): New.
(proc_parameter_file): Use new func to extend the parameter list.
* g10/passphrase.c (passphrase_to_dek_ext): Print a diagnostic of
gcry_kdf_derive failed.
* g10/keygen.c (proc_parameter_file): Print a diagnostic if
passphrase_to_dek failed.

* g10/gpg.c: Include shareddefs.h.
(main): Add option --pinentry-mode.
* g10/options.h (struct opt): Add field pinentry_mode.
* g10/passphrase.c: Include shareddefs.h.
(have_static_passphrase): Take care of loopback pinentry_mode.
(read_passphrase_from_fd): Ditto.
(get_static_passphrase): New.
(passphrase_to_dek_ext): Factor some code out to ...
(emit_status_need_passphrase): new.
* g10/call-agent.c (start_agent): Send the pinentry mode.
(default_inq_cb): Take care of the PASSPHRASE inquiry. Return a
proper error code.
(agent_pksign): Add args keyid, mainkeyid and pubkey_algo.
(agent_pkdecrypt): Ditto.
* g10/pubkey-enc.c (get_it): Pass new args.
* g10/sign.c (do_sign): Pass new args.
* g10/call-agent.c (struct default_inq_parm_s): New. Change all
similar structs to reference this one. Change all users and inquire
callback to use this struct, instead of NULL or some undefined but not
used structs. This change will help to eventually get rid of global
variables.
--
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.
* common/agent-opt.c: New.
* common/shareddefs.h: New.
* common/Makefile.am: Add new files.

* scd/iso7816.h (struct pininfo_s): Rename from iso7816_pininfo_s.
Change meaning of MODE.
(pininfo_t): Rename from iso7816_pininfo_t.

(ccid_transceive_secure): Follow the change of PININFO_T.
* scd/app.c: Include "apdu.h" after "iso7816.h".
* scd/iso7816.c (iso7816_check_keypad, iso7816_verify_kp)
(iso7816_change_reference_data_kp): Follow the change of API.
* scd/apdu.c (struct reader_table_s): Change API of CHECK_KEYPAD,
KEYPAD_VERIFY, KEYPAD_MODIFY to have arg of PININFO_T.

(create_blob_finish): Switch to SHA-1.
* kbx/keybox-dump.c (print_checksum): New.
(_keybox_dump_blob): Print the checksum and the verification status.
--
The checksum was never used in the past. Due to fast SHA-1
computations in modern CPUs we now use SHA-1. Eventually we will
support a First blob flag to enable the use of a secret or public
HMAC-SHA1. The first may be used for authentication of keyblocks and
the latter to mitigate collission attacks on SHA-1. It is not clear
whether this will be useful at all.
