help needed desperately: gpg --decrypt hanging

OK. Perhaps I was the brain dead one <<and with Halloween running rampant
through the company today it could be contagious>>.
Perhaps you already know this and I just didn't pick it out from the Perl
script. However, the data to be encrypted and the passphrase cannot both
come through STDIN (or FD 0). I would suggest that you send the passphrase
through STDIN (and use the --passphrase-fd 0 command line option) and send
the data to decrypt through a named pipe. Perhaps something like:
mknod mydata p
cat info_to_decrypt > mydata &
cat my_pass_phrase | gpg --no-tty --passphrase-fd 0 --decrypt mydata >
Does that help or am I still barking up the wrong tree?

Sorry Steve, I don't think I explained the problem well enough. If I
run, on the command line:
Then I pass it the encrypted text to decrypt, and then I give it the
password, it just hangs! It sits and sits and sits...and we get
Thanks for your help!
