Encrypted bank account info

[Chris Travers <..hidden..>]

Hi all;

I was reviewing the requirements for 1.3 from a security perspective
and thinking we really should encrypt customer/vendor bank account
info.  If nothing else, I think this should be in a recommended add-on
if not in the main branch.

Anyone have any ideas as to the best way to do this?

I have a few ideas but still not quite completely formed.....

Best wishes,
Chris Travers
