I thought I had indicated my intention to take the advice offered and
put the important password (a master password) in a separate file and
source it from the script.

The script itself does not need encrypting if the master password is
not in it. However, I would not want the separate file unencryted
because the master password gives access to passwords for all sorts of
websites.

Users actually have to know this master password. It is a long phrase,
not too hard to memorise but tedious to type. As I have said, encrypting
the separate file with scrypt allows me to get the decryption password
down to a more user-friendly 14 characters. The prompting for the
password is done by scrypt. There is no point in multiple people having
different passwords. All users here are trusted.
