Is there a way that the SSN or SIN numbers can be better hidden? I looked at the dump for the tables and I can see the SSN/SIN numbers in plain-text stored in the tables. With these numbers being pretty important and the possibility that some might install this on a a web server, I think it's better that this is looked into and converted into a Hash value like the passwords are using the value given in the salt.

Passwords are encrypted with a one-way encryption, they can never be decrypted, so this would make storing SIN/SSN's useless if we did that as we would never be able to decrypt them to print them on tax forms.
