                               Encryption Program
                                  Version 1.20


	Encryption Program is an encryption program for Windows 95.  It can
be used to encrypt and decrypt any files.  It can be distributed and used
freely.

	Encryption Program uses bitwise exclusive OR encryption.  Thus,
running a file through it once with a given password changes the contents
with a filter specific to the password, and running the new file through
with the same password creates a file with the same content as the original.
The operation for encrypting and decrypting is the same; the encryption
process is functional, producing an unique answer each time.

	You can encrypt a file by adding it to the list box on the left
side of the Encryption Program window.  Press the "Add a file..." button
and select the file you want or drag a file or files from another window and
drop them in the Encryption Program window.  You will see the file name(s)
appear in the list box.  If you decide you don't want to encrypt a file,
you can remove it from the list by selecting it and pressing the "Delete
File" button.

	When you've put all the files you want to convert in the file list,
type your password into the password and confirmation boxes.  Your password
must be six characters in length or greater, and must be identical in both
boxes.  When these conditions are met, and there are files in the file list,
the "Run" button will become available.  Press it, and the files in the
list will be encrypted/decrypted and will disappear from the list.  If the
encryption fails for some reason, a message box telling you this will appear
and the name will remain on the list.

	By default, Encryption Program checks to see if the files you have
given it have the extension "cpt".  If they do, the newly converted file
will have the same name with the "cpt" removed.  If they don't, the "cpt"
extension will be added.  Thus, when you first encrypt a file it will be
designated by the "cpt" extension, and when you decrypt a "cpt" file the
original filename will be restored.

	Also by default, the "Ask before overwriting a file" check box is
checked.  When the encryption program runs, it will ask whether you want to
overwrite any files which will be overwritten in the process.  If you don't
want such prompting, you can deselect this button.  However, you must be
careful if you do; your old files may be overwritten without your consent.

	You can click on the "Exit" button to quit the program.

Author's note:

	I hope you like this little program.  It took me only a little time
to write, so I won't bother you for money or anything like that.  I plan to
use it myself for files exposed to the Internet and intranets I don't want
other people to read.  It's fast and safe, and virtually impregnable.

	If you have any questions or comments or suggestions, please e-mail
me at ccarrill@fas.harvard.edu.  I don't get to check my mail very often,
but I promise I'll get back to you as soon as I am able.  In reality I do
get to everyone, so if you have anything to say feel free to send me a note.
It doesn't take much time, really.

	Be forewarned, though.  I'm not responsible if you encrypt
command.com and your system doesn't boot, or you encrypt an important
document and forget the password.  If this program causes any other
problems, be they your fault or its own, I'm similarly not responsible.
You use it at your own risk.

	Other than that I have nothing much to say.  Safe and happy computing
to you.  I hope this program comes in handy in some way.  I like simple
programs you can get for free and use easily that solve a specific problem,
saving you the time of writing something yourself.  That's what this is
designed to be: a little utility for people who need fast encryption.
Given, there are a lot of encryption algorithms out there, and you could
buy any of a number of utility packs and get an array of them.  But this
is free, and it's here.  Use it in good health.
