Actually; not true.

There is an undocumented feature in the engine (goes back to IB) which
provides the ability to encrypt data in the database, using a UDF -- I
don't recall if it applies to individual records or complete database

The only problem, which is why it isn't really recommended, is that it
doesn't really help much:

If you can access the physical database file to begin with, you could
reasonably be able to access the encryption UDF!
