Unfortunatly another problem is what other FREE for comercial use cyphers
are there? IDEA is not free... :)
This DES has an NSA backdoor has been hashed in and out on sci.crypt
forever... What appeared to be a common theme was that, yes, the NSA

to run Triple-DES, as it is more secure than Single 56bit DES.
Follow ups should go to sci.crypt... :)
