Can't seem to get #2 to work - do you have an example?

possible. I get a "Broken pipe" printed to STDOUT and my script cannot
continue. Is there a way to catch the fact that the passphrase was bad
before attempting to print the encrypted file's contents to stdin as
in the GnuPG::Interface examples?
Three things you can do, off of the top of my head:
1: Get the PID of the running GnuPG process (the return from "decrypt"),
and check if it's still running (send a signal of 0).
2: Read the status-fd from GnuPG; it would report a bad/good passphrase
before you had to send in the input.
3: Use the test_default_key_passphrase method of GnuPG::Interface to
pre-check the passphrase.
