Static strings in gpg-agent need to be translated according to the
locale set by the caller. This is required so that a gpg-agent can be
started in one locale and a gpg can be run in another. If we don't do
this the static strings (prompt, buttons) are not or in the wrong
locale translated while dynamic strings (e.g. key description) uses
the locale of gpg.
This is only the first part of the change the actual local switching
still needs to be implemented.

Given that extract_private_key is not file local it is good to have some

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).

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.

A test case leading to a segv in Libgcrypt is
gpg-connect-agent \
"READKEY 9277C5875C8AFFCB727661C18BE4E0A0DEED9260" /bye
The keygrip was created by "monkeysphere s", which has a comment.
gcry_sexp_build_array expects pointers to the arguments which is quite
surprising. Probably ARG_NEXT was accidentally implemented wrongly.
Anyway, we can't do anything about it and thus need to fix the check
the users of this function.
Some-comments-by: Werner Koch <wk@gnupg.org>
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.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
Quite some changes were needed but in the end we have less code than
before. Instead of trying to do everything with MPIs and pass them
back and forth between Libgcrypt and GnuPG, we know use the
S-expression based interface and make heavy use of our opaque MPI
feature.
Encryption, decryption, signing and verification work with
self-generared keys.
Import and export does not yet work; thus it was not possible to check
the test keys at https://sites.google.com/site/brainhub/pgpecckeys .
The following works:
gpg2 --gen-key (ECC)
gpg2 --list-keys
gpg2 --list-packets ~/.gnupg/pubring.gpg
gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>
ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.
char * vs. unsigned char * warnings. The GNU coding standards used to
say that these mismatches are okay and better than a bunch of casts.
Obviously this has changed now.
