# this was one of the learning projects
# i've found useful for starting Tkinter
# and for understanding concept of message encryption in a very very simple version..
# NB-NOTE: THE ORIGINAL PROJECT
# CAN BE FOUND IN THE FOLLOWING ADDRESS:
# https://www.geeksforgeeks.org/python-message-encode-decode-using-tkinter/


# This Project is redesigned and updated in a more understandable way
# by me! (/https://github.com/AmirHosseinRnj1)
# If you have any problem running or understanding this project,
# feel free to make contact with me...


#TKINTER MODULE SETUP
