Ho, cyphernauts! My $.02 votes for SecureDevice as an MS-DOS encryption mechanism because: 1) It works within a file (or files) rather than requiring a dedicated hard disk partition; you can put up and take down encrypted "drives" without wiping out the whole disk drive and repartitioning. (VERY handy when you suddenly need to increase the size of your "drive" *RIGHT NOW*). 2) It keeps a regular DOS directory structure within the "drive" file; you set up the "drive" one time and then just throw stuff in it at will. You can encrypt single files a variety of ways, but then you have to manage them all - this way, you just chuck 'em in the safe together. 3) In a pinch, you can move the whole encrypted "drive" from place to place - since it's a self-contained data file and is encrypted throughout, you can FTP it all over the place as a binary file without hurting it. The only time I've gotten in trouble with it was when I had SmartDrive turned on for the encrypted "drive" and went down hard; now, I have a SMARTDRV -D: or whatever in my AUTOEXEC so that SmartDrive won't try to buffer I/O to the encrypted drive. My one and only gripe - it won't work under Windows NT 3.5 ! I have to boot DOS (blech!) to get at the encrypted drive. (Hint, Hint, Hint....) -Philippe
