Krypto Manual
************

This program encrypts and decrypts .txt files. 

*First specify which file you want encrypting\decrypting using the browse 
button next to the first text box or typing the file location directly into the box.

*Next specify what you would like the encrypted text file to be saved as 
using the second browse button or typing the file destination directly into the box.

*Third you must enter a unique keyword that will be used to encrypt/decrypt your
your files. Remember the keyword you use as it is needed to decrypt the text file
again. The keyword must be 3 to 6 characters in length, it may contain letters,
numbers and special characters (such as ! " @  % $ ^)

*Once both files have been specified with a valid word press the 
"Encrypt\Decrypt" button, this will produce the encrypted or decrypted 
file in the specified location.

WARNING - If you select the same file for both options then the old file 
will be replaced by the new file.
