What is DeepCrypt?

     DeepCrypt is a tool to encrypt/decrypt your files and data.
     Every file encrypted with DC is safe and I mean safe. If you
     forget your keynumber your files can be lost for ever!

     The DeepCrypt archive may only distributed in its unchanged, original form.
     DeepCrypt is free-/giftware. Spread it!


     The contents of the DC archive are:
     

          DeepCrypt...............the executable
          DeepCrypt.info..........the icon (ugly but mine)
          DeepCrypt.doc...........german docs
          DeepCrypteng.doc........this document (a little bit smaller:-)
          Neu.font................the font :-)
          neu (dir)...............the font directory
          Changes.................listed changes from V1.1 - *


System requirements:

     OS2.0 (V37.xxx) / OS3.0
     AMIGA :-)     
     Enough mem....


DeepCrypt gadgets:

    DeepCrypt has a small number of gadgets. Namely there are:

     
     "Load"         Load a file
     
     "Save"         Save an encrypted or unencrypted file

     "Crypt"        Enrypt a file

     "Decrypt"      Decrypt a file

     "BClear"       Clear the actual filebuffer. The buffer will be cleared
                    whether the files has been processed or not.
     
     "Keynumber"    You should enter your crypt/encrypt keynumber here.
                    The keynumber may be eight digits long. 

     "Shrink"       Shrink DCs window. 

     "Icon|
      Menu "        Toggle if Dc appears as a DockIcon or as a ToolsMenu.

     "SpeedUp
      Buffer "      You can select several types of buffer-handling.
                    Select "Adaptive" for automatic buffer adaption.
                    On low-memory-AMIGAs you can also select "20KB" or
                    "50KB", but it is not recommendet to user of an
                    1-or-above-Meg AMIGA.
   
     Every gadget can be accessed pressing the corresponding key ( the one
     underlined in the gadget-text).
     
     It is now possible to load a file by drag`n`droping its icon over DCs
     window.
     
     If you shrink DCs window with the selected "Icon" function you can
     do the same with the DockIcon (I mean Drag`n`Drop). If you doubleklick
     the DockIcon DC will appear in unchanged form, except for the SpeedUp-
     buffer-gadget, it will show "Adaptive" (the default).

     If you shrink DC with the "Menu" option, a Menuitem named "DeepCrypt"
     (wow!:-) will appear in the WB-"Tools" menustrip. Select "DeepCrypt"
     to expand the window again.

The display:

     "Avail.Mem is."     Shows the available memory.

     "Filesize is"       Shows the size of the loadet file.

     "To do"             A progress indicator. It starts at the actual
                         filesize and counts to zero.


How does DeepCrypt work?

     DeepCrypt uses a Algorithm used by military forces within the NATO.
     Many Voice/Document cryptors work with it (the german elcovox for 
     example).

     DeepCrypt is able to crypt files several times with several keynumbers.
     To decrypt a file you must decrypt it in exactly the same order as 
     you crypted it.

     
How to use it:

     You load a file into the buffer then you can enter a keynumber
     (it should be an easy-to-remember value).
     At the moment you select "crypt", the file will be processed.
     After crypting the file you can save it or recrypt it (even with the
     same keynumber).
     
     NOTE: If you crypt a file five times with "123456" you must encrypt it
           five times with "123456" too!

     To decrypt a file you must do the same with the "decrypt" function.
     If you have crypted a file and you don`t want to save it with the 
     actual entered keynumber, you can select "BClear" to clear the buffer
     or you start "decrypt" and enter a new keynumber AFTER "decrypt".


Endnote:

     Pffffff......ok if anyone is able to debug :-) my english docs he should
     do that. :-))  (Like Daniel did)

     In later versions DeepCrypt should be able to process whole devices like
     a disk or a HD-patition for example....but till then........
