SecureDrive 13x Low-level (Disk block level) encryption for MS-DOS You can enciper a logical or physical drive (A, B, D, etc.), after which, it can only be accesssed via "logging in" with the LOGIN command. Once done, a TSR is loaded that transparently decrypts the information on the fly, so you can access the otherwise encrypted information from DOS, Windows, etc, and it's totally transparent to you, your applications, etc. Recommended but not included utility is FIPS09.ZIP which can be found in any SIMTEL20 REPOSITORY mirror (ie: wuarchive.wustl.edu) for non-destructivly partitioning an existing drive. THis is great for shared computers, notebook/laptop machines and disks passed from person to person containing sensitive material.
