Where is SecureDevice? wuarchive directory missing..

Hello, all! I have just changed jobs within the company, and now I find that my PC is not as secure as I'd like. (Long story.) I'm looking for SecureDevice, hoping that it will let me create a secure area on my hard drive. I ftp'ed to wuarchive.wustl.edu, changed directory to /pub/msdos_uploads, then tried to change directory to cryptography only to find that the directory does not exist! Pointers? Suggestions? Thanks for your time! Philippe Nave P.S. Does anybody have a FAQ or something about how to integrate PGP with Microsoft Mail? (Note the lack of a PGP signature while I'm getting my act together..)
