Actually, it's not security they are after but rather are using encryption
as a means of "making data disappear". Some one wrote an article on them and
their technology, I'm not sure who. I don't know if they do a good job at
the cryptography or not, but the concept is not to secure data but rather to
make it go away, and using crypto to accomplish this. The real question is
what security measures are they using for the storage of the keys on the
server and the transmission of the key at decrypt time.
