CHAPTER  6

                        FILE  ENCRYPTION   



  A special feature of The WALMYR Pen Pal  is  a  procedure  that
enables  you  to  encrypt  any  text  file provided that the file 
consists of strict ASCII  text.   The  procedure  is  useful  for
protecting sensitive records of any kind.  It can also be used to
de-crypt any of the completed questionnaires that are produced by
the program.


ENCRYPTING A FILE   

  In  order  to  ENCRYPT  a data file or message, choose option A 
from the encryption menu of the program.  Then enter the name  of
the  file  that  you wish to ENCRYPT.  Then enter the name of the 
output file where you want the encrypted data file or message  to
be  stored.  When you do that, the program will immediately begin
to encrypt your file.


DECODING MESSAGES  

  In order to DECODE a datafile or message, choose option B  from
the  encryption  menu  of the program.  You will then be asked to 
enter the name of the file that you wish  to  decode.   You  will
then be asked to enter the name of the output file where you want
the  DECODED message to be stored.  When you do that, the program
will immediately begin to decrypt your file.


VIEW AN ENCRYPTED FILE 

  Option C of the encryption menu allows you to view an encrypted 
file on screen  without  storing  the  decrypted  version  on  an
external  file.  When you choose this option you will be asked to 
enter the name of the file that you wish to view.   When  you  do
that  the file will be decrypted and displayed on screen for you.


  You may exit instantly by pressing the * key beside  the  shift
key on the right side of your keyboard.  This will help to insure
privacy  while you are viewing confidential data or messages.  If 
someone approaches who should not see the file, just press the  *
key and you will return immediately to the main menu.
