64 bit OS brings at least one advantage, if you use it with full ASLR you are essentially immune to buffer overflow attacks. That is a huge security advantage. Also you can run full hardware virtualization solutions without hardware virtualization support if the product uses binary translation, like virtualbox does. Anyone who can click next and enter a password can get the same exact benefits just by using Truecrypt without all of this other trash attached to it well documented unless they have your password (again shut your mouth and lawyer up) or key (very difficult and unlikely) You know that whirlpool is a hashing algorithm right? It can be used with AES but it isn't adding another layer of symmetric encryption to do so. He who puts money over security will be raped in jail
