MacUser Security 1.1

I came across the following in the comp.sys.mac.etc faq under security:

If you need to protect sensitive data I recommend that you encrypt it with software such as MacUser Security 1.1.

Does anyone know anything about this program and whether or not it is worth a damn? Would this be more on-topic at sci.crypt or comp.security? Walter Mitty <na26540@anon.penet.fi>
