Hi Justin - TBH I'm not sure what the word is you're looking for - perhaps 'passphrase'?

Scott - the issue is that the web interface uses JSON, while the Perl library wants a Perl hashref, so the syntax is different. I'm not making any promises, but I might be able to alter the Perl so it accepts a JSON string or a Perl hashref. I've added it to my list of things to look at over the Christmas holidays.
