No, you'll have to pipe it through a file descriptor with --passphrase-fd. But with the echo command it can be done on a commandline too on fd 0: echo password | gpg --passphrase-fd 0 --decrypt / --encrypt. For some reasons I don't completely understand the GnuPG developers feel this is less insecure than a normal commandline (you're certainly not the first to ask this...). > In my program, I can only use command line to execute the commands.

I don't know what language your application is in, but for C or C++, see pipe(), dup2() and fork(). -- ir. J.C.A.
