- This is taken from the DiskProtection documentation to give you
- a more detailed impression of the program. See the file
- "Announce.readme" on where to find the program.

-
- 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.
-
- Encryption uses IDEA, FEAL or DES. If the XPK-interface to
- sublibraries was improved, it would be possible to encrypt with these
- or other algorithms via XPK. Any number of passwords can be used.
-
- Passwords are requested from the user on demand. They may be made
- resident in order to avoid requests after a reset. Therefore
- DiskProtection can be used for mailboxes without permanent
- control. Alternatively passwords can be hidden in arbitrary files. The
- computer may be protected from unauthorized use.
-
- There is a preferences program with GUI. The encryption of a
- partition can be changed anytime: It is automatically encrypted
- renewedly, so unencrypted data can be converted.
-
- DiskProtection needs an Amiga with at least OS 2.0. It has a
- graphic user interface designed with Triton V1.3. Locale is supported,
- catalogs and translations of the complete documentation exist in
- English and German. The documentation is included in AmigaGuide-,
- ASCII- and DVI-format and can be displayed as contextsensitive online
- help.

- Concept of DiskProtection
- *************************
-
- Approach of DiskProtection
- ==========================
-
- There are a lot of programs encrypting files in many different ways.
- Most the time the disadvantage is that one can only use the file again
- in other programs after manually decrypting it or has to use programs
- capable of reading the file.
-
- One far more comfortable and flexible way to protect one's data is a
- filesystem or handler, encrypting data or controlling access to files.
- Solutions of this kind are e.g. MultiUserFilesystem and XFH, that
- supports the XPK libraries "IDEA" and "FEAL" for encryption. However,
- the directory and all filenames are still readable without knowing the
- correct password. So a stranger can still see what is on one's
- harddrive and gets some hints on the contents of a file. This knowledge
- could even be used for an attack.
-
- DiskProtection chooses a different approach. Its core is an exec
- device that encypts every single disk before it is written to floppy
- disk or harddrive. That way any filesystem can be used. Without this
- device and the password used to encrypt the disks one only gets an
- `Unreadable Disk", without any filename, directory or file contents
- readable in clear.
-
- This concept has a different disadvantage, though: Preferences can
- only be set for one unit and therefore only for one partition or disk
- as a whole. Different encryption in different directories or of
- different files is not possible.
-
- Licence
- =======
-
- DiskProtection is distributed as shareware. The package may be
- distributed freely, as long as the following conditions are met:
-
- 1. Any distribution has to contain all files of this archive without
- any changes.
-
- 2. This package may be freely distributed in mailboxes,
- InterNet/UseNet, software libraries like the one from Fred Fish,
- Aminet CD-ROMs and similiar electronic chanels.
-
- 3. Disk magazines and other service providers that take additional
- fees for transmitting the data are not allowed to distribute it
- without permission of the author!
-
- Is you want to use the program regularly you should send me at least
- 20,-DM or an equivalent amount in a different currency. Please keep in
- mind that cheques drawn on foreign banks are difficult to cash. Euro
- cheques and cash are prefered.
-
- In case the payment of the shareware fee is to difficult or the
- program is used to rarely to pay, I'm satisfied with an interessting
- postcard or any other small gift. Bank account and address are given
- in Address.
-
- This version of DiskProtection is not crippled in any way.
- Therefore the shareware fee is a payment for the goods you already have
- received, but also gives permission to use any future version.
- Registered users can be send the most recent version by email. However,
- this is only possible with post if the nescessary postage is refunded,
- too.
-
- New, improved versions will be produced if I'm motivated enough and
- this concept works. Otherwise it might be possible that future releases
- will only be fully functional with a keyfile.
