Thanks, we find the solution with help of an user (Lee Elcocks), the problem
was to write an space between password and pipe.
Echo "mypasswd"| gpg.exe ...... use it without space between "mypasswd" and
|
Thanks for your effort, Werner, we're using the first one (only had to
remove empty space on the .bat) but your solution seems ok too.
Regards.
Gabi.

Note that --help does not show all options. See the man page for a
complete list.

It is the same on all platforms.
What you need to use is the command gpg-preset-passphrase to tell the
gpg-agent the passphrase in advance.
gpg-preset-passphrase [options] [command] keygrip
The gpg-preset-passphrase is a utility to seed the internal cache
of a running gpg-agent with passphrases. It is mainly useful for
unattended machines, where the usual pinentry tool may not be
used and the passphrases for the to be used keys are given at
machine startup.
Passphrases set with this utility don't expire unless the
--forget option is used to explicitly clear them from the cache
--- or gpg-agent is either restarted or reloaded (by sending a
SIGHUP to it). It is necessary to allow this passphrase
presetting by starting gpg-agent with the --allow-
preset-passphrase.
gpg-preset-passphrase is invoked this way:
gpg-preset-passphrase [options] [command] keygrip
keygrip is a 40 character string of hexadecimal characters
identifying the key for which the passphrase should be set or
cleared. This keygrip is listed along with the key when running
the command: gpgsm --dump-secret-keys. One of the following
command options must be given:
[...]
For use with gpg you can use
gpg2 --with-keygrip -K
to view the keygrip.
Salam-Shalom,
Werner
