Build A Base64 Encrypt and Decrypt Tool – Python Tkinter GUI Tutorial 216

In this video we’ll build a Base64 Encrypt and Decrypt tool for Tkinter and Python.

Converting text to Binary is pretty easy with Python and Tkinter. In this video we’ll create an encrypter and decrypter tool using pybase64.

You’ll need to pip install pybase64.

Python Code: enc.py
(Github Code)

from tkinter import *
import pybase64
from tkinter import messagebox

root = Tk()
root.title('Codemy.com - Encrypt/Decrpt Base64')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x400")

def clear():
	#Clear boxes
	my_text.delete(1.0, END)
	my_entry.delete(0, END)

def encrypt():
	# Get text from text box
	secret = my_text.get(1.0, END)
	# Clear the text box
	my_text.delete(1.0, END)

	# Logic for password
	if my_entry.get() == "elder":
		# Convert to byte
		secret = secret.encode("ascii")
		# Convert to base64
		secret = pybase64.b64encode(secret)
		# Convert it back to ascii
		secret = secret.decode("ascii")
		# Print to text box
		my_text.insert(END, secret)

	else:
		# Flash a message if wrong password
		messagebox.showwarning("Incorrect!", "Incorrect Password, Try Again!")

def decrypt():
	# Get text from text box
	secret = my_text.get(1.0, END)
	# Clear the screen
	my_text.delete(1.0, END)
	
	# Logic for password
	if my_entry.get() == "elder":
		# Convert to byte
		secret = secret.encode("ascii")
		# Convert to base64
		secret = pybase64.b64decode(secret)
		# Convert it back to ascii
		secret = secret.decode("ascii")
		# Print to text box
		my_text.insert(END, secret)

	else:
		# Flash a message if wrong password
		messagebox.showwarning("Incorrect!", "Incorrect Password, Try Again!")
