Create the "recovery URL" for ephemeral labeling

[BjarniRunar]

... or maybe not? Perhaps this is a "passcrow.org" thing.

Anyway, the idea is that you can print a label for a drive or laptop, and the label is an URL and a recovery code - something people recognize and know what to do with (the word "passcrow" will mean nothing to most people, but people know what URLs are for).

When they visit the URL they should be given instructions on how to install passcrow and use the code to initiate recovery.
