No problem.  GPGME does it this way.  The trick is the option
--enable-special-filenames and to pass the fd in this format "-&N".

  gpg --enable-special-filenames --verify --batch -&5 -&6

Assuming you have them in fds 5 and 6.

Using GPGME is of course easier because it has this secret knowledge ;-)



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
