Attention: This is not the program DiskProtection itself!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Due to USA export restrictions for cryptographic software the program may
not be distributed on AmiNet. This archive contains only the announcement
sent to c.s.a.announce together with the chapter of the documentation
describing the program.

If you are interested in the program, look at the AmiNet site
"ftp.uni-paderborn.de" or "kelly.uni-paderborn.de" in the directory
"util/crypt" for the last official version. You will also find the most
recent (beta-)version on my WWW home page:
http://www.uni-karlsruhe.de/~un60


Description
~~~~~~~~~~~
DiskProtection encrypts data totally invisible for the user while writing to
disk. All blocks are encrypted, so the directories are protected, too.
DiskProtection supports all exec devices, i.e. harddrive partititions,
floppy disks, but not the RAM-disk. Any filesystem can be used.

It features:
 - encryption with IDEA, FEAL, DES
 - (XPK-)interface for additional algorithms
 - configurable with easy to use preferences program
 - encryption can be changed anytime
 - resident passwords (for use with mailboxes)
 - access protection
 - builtin screenblanker
 - GUI driven, localized
 - German and English documentation (ASCII, DVI, AmigaGuide)
 - context sensitive online help
 - ...

Changes
~~~~~~~
 - new: fast, but unsafe encryption algorithm
 - new: DPInit, a tool to start DiskProtection without mounting anything
 - new: an example source code for your own encryption libraries
 - bug fixes: "Hide in File" was somehow buggy,
              sorting order of XPK libraries was reversed

Requirements
~~~~~~~~~~~~
DiskProtection requires OS2.0 and Triton-Library 1.4. A minimum distribution
is included in this archive, but you should better look out for the complete
archive "util/libs/tri14usr.lha" on AmiNet.
