There are other smaller changes not described above.
This change tries to avoid new error messages so not to increase the
the number of translated strings or break too many existing
translations. It also tries to use existing strings and changes the
quoting to the most common style used in gpg.
Key specifications should in general use double quotes. Other values
should use single quotes. However. sometimes it is not easy to
distinguish between values given on the command line and key
specifications. According to old GNU coding standards diagnostics
should not start capitalized - whether this is a good idea is a
different thing but we used this rules for most strings. However,
strings which are used interactively should be properly capitalized
and end with a dot.

v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
use these old and broken keys. Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.
We have also kept support for v3 signatures until now. With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures. What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures. The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages. These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

* configure.ac: Added --enable-large-secmem option.
* g10/options.h: Add opt.flags.large_rsa.
* g10/gpg.c: Contingent on configure option: adjust secmem size,
add gpg --enable-large-rsa, bound to opt.flags.large_rsa.
* g10/keygen.c: Adjust max RSA size based on opt.flags.large_rsa
* doc/gpg.texi: Document --enable-large-rsa.

This is a cherry-pick of 534e2876acc05f9f8d9b54c18511fe768d77dfb5 from
STABLE-BRANCH-1-4 against master
Some older implementations built and used RSA keys up to 16Kib, but
the larger secret keys now fail when used by more recent GnuPG, due to
secure memory limitations.
Building with ./configure --enable-large-secmem will make gpg
capable of working with those secret keys, as well as permitting the
use of a new gpg option --enable-large-rsa, which let gpg generate RSA
keys up to 8Kib when used with --batch --gen-key.

GnuPG-bug-id: 1732
* g10/gpg.c (aFullKeygen): New.
(opts): Add command --full-key-gen.
(main): Implement it.
* g10/keygen.c (DEFAULT_STD_ALGO): Replace wrong GCRY_PK_RSA although
the value is identical.
(DEFAULT_STD_CURVE): New.
(DEFAULT_STD_SUBALGO): New.
(DEFAULT_STD_SUBKEYSIZE): New.
(DEFAULT_STD_SUBCURVE): New.
(quick_generate_keypair): Use new macros here.
(generate_keypair): Add arg "full" and fix call callers. Do not ask
for keysize in non-full node.
(ask_user_id): Add arg "full" and simplify for non-full mode.
* agent/cache.c (last_stored_cache_key): New.
(agent_get_cache): Allow NULL for KEY.
(agent_store_cache_hit): New.
* agent/findkey.c (unprotect): Call new function and try to use the
last stored key.
* g10/revoke.c (create_revocation): Add arg CACHE_NONCE and pass to
make_keysig_packet.
(gen_standard_revoke): Add arg CACHE_NONCE and pass to
create_revocation.
* g10/keygen.c (do_generate_keypair): Call gen_standard_revoke with
cache nonce.

This patch adds two features:
1. The key for the last passphrase successfully used for unprotecting
a key is stored away. On a cache miss the stored away passphrase is
tried as well. This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase. See the
code for more comments.
2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt. Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).
* common/openpgpdefs.h (PUBKEY_ALGO_EDDSA): Change to 22.
* g10/keygen.c (ask_curve): Reword the Curve25519 warning note.
--
In the hope that the IETF will eventually assign 22 for EdDSA using
the draft-koch-eddsa-for-openpgp-01 specs we start using this number.
* g10/gpg.c (oRFC1991, oPGP2): Remove
(opts): Remove --pgp2 and --rfc1991.
* g10/options.h (CO_PGP2, CO_RFC1991): Remove. Remove all users.
(RFC2440, PGP2): Remove. Remove all code only enabled by these
conditions.
* tests/openpgp/clearsig.test: Remove --rfc1991 test.
--
The use of PGP 2.c is considered insecure for quite some time
now (e.g. due to the use of MD5). Thus we remove all support for
_creating_ PGP 2 compatible messages.
* g10/gpg.c (aQuickKeygen): New.
* g10/misc.c (is_valid_user_id): New stub.
* g10/keygen.c (quickgen_set_para): New.
(quick_generate_keypair): New.
--
Note that the validation of the specified user id has not yet been
implemented.
* common/iobuf.c (direct_open): Add arg MODE700.
(iobuf_create): Ditto.
* g10/openfile.c (open_outfile): Add arg RESTRICTEDPERM. Change call
callers to pass 0 for it.
* g10/revoke.c (gen_desig_revoke, gen_revoke): Here pass true for new
arg.
* g10/export.c (do_export): Pass true for new arg if SECRET is true.

GnuPG-bug-id: 1653.
Note that this works only if --output has been used.
