Commit 91b826a388 was not enough to
avoid all sign extension on shift problems.  Hanno Böck found a case
with an invalid read due to this problem.  To fix that once and for
all almost all uses of "<< 24" and "<< 8" are changed by this patch to
use an inline function from host2net.h.

371c2b14b0 gpg: Warn about (but don't fail) on scdaemon options in gpg.conf.
* g10/gpg.c: Add config options that should belong in scdaemon.conf
* g10/main.h, g10/misc.c (obsolete_scdaemon_option): New.

--

In gpg2, the following options are only relevant for scdaemon:

 reader-port
 ctapi-driver
 pcsc-driver
 disable-ccid

but in gpg1, they are options for gpg itself.

Some users of gpg1 might have these options in their
~/.gnupg/gpg.conf, which causes gpg2 to fail hard if it reads that
config file.

gpg2 should not fail hard, though giving a warning (and suggesting a
move to scdaemon.conf) seems OK.

This patch does *not* reintroduce any documentation for these options
in gpg.texi, even to indicate that they are "dummy" options, since
scdaemon.texi contains the appropriate documentation.

We have a similar feature in GnuPG-1.  Although we don't shrink the

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones.  This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.

This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA.  As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF.  Note that EdDSA (Ed25519)
does not yet work and that more changes are required.

The ECC support is still broken right now.  Needs to be fixed.

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.

b4d9f8dbc8 Add tweaks for the not anymore patented IDEA algorithm.
* g10/keygen.c (keygen_set_std_prefs): Include IDEA only in PGP2
compatibility mode.
* g10/misc.c (idea_cipher_warn): Remove.  Also remove all callers.
* common/status.h (STATUS_RSA_OR_IDEA): Remove.  Do not emit this
status anymore.
--

To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation).  It does not make sense to suggest the use of this
old 64 bit blocksize algorithm.  However, there is old data available
where it might be helpful to have IDEA available.

30ec869b8c gpg: Fix segv with RSA_S keys.
* g10/misc.c (pubkey_get_npkey, pubkey_get_nskey)
(pubkey_get_nsig, pubkey_get_nenc): Map all RSA algo ids to
GCRY_PK_RSA.
--

The problem is that Libgcrypt has no more support for the alternate
RSA ids and thus if asking for the number of parameters, they will
return zero.  Now, this leads to packing the key parameters into an
opaque MPI but because the algorithm id is actually known to GPG, it
assumes valid RSA parameters.

An example key with RSA_S is 0x5434509D.
