![]() It details the methods of attacks along with security principles. The aim of this course is to explore security fundamentals related to computer data, information and Network. Many organizations will identify information as an area of their operation that needs to be protected as part of their system of internal control.Ĭomputer and Network Security is the collection of technologies, standards, policies and management practices that are used in order to obtain a high level of security. The threats to information systems from criminals and terrorists are increasing. The public is increasingly concerned about the proper use of information, particularly personal data. Plaintext = decrypt(self.cipher_entry.In today's high technology environment, organizations are becoming more and more dependent on their information systems. Self.cipher_clear = tk.Button(master, text="Clear",Ĭommand=lambda: self.clear('cipher'), font=FONT).grid(row=2, column=3)Ĭiphertext = encrypt(ain_entry.get(), key) crypt_button = tk.Button(master, text="Decrypt",Ĭommand=lambda: crypt_callback(), font=FONT).grid(row=2, column=2) Textvariable=self.ciphertext, width=50, font=FONT) Self.cipher_label = tk.Label(master, text="Ciphertext", fg="red", font=FONT).grid(row=2, column=0) Self.key_entry = tk.Entry(master, textvariable=self.key, width=10, font=FONT).grid(row=1, column=1, Self.key_label = tk.Label(master, text="Key", font=FONT).grid(row=1, column=0) ain_clear = tk.Button(master, text="Clear",Ĭommand=lambda: self.clear('plain'), font=FONT).grid(row=0, column=3) Self.encrypt_button = tk.Button(master, text="Encrypt",Ĭommand=lambda: self.encrypt_callback(), font=FONT).grid(row=0, column=2) Textvariable=aintext, width=50, font=FONT) ain_label = tk.Label(master, text="Plaintext", fg="green", font=FONT).grid(row=0, column=0) Self.ciphertext = tk.StringVar(master, value="") zip file containing the code for this app here: Caesar Cipher Tkinter App. This basic application contains many of the elements you will need in your own applications, and provides an excellent starting point for learning Python Tkinter GUI programming. The code below uses the Python Tkinter library, which is very popular for building graphical user interfaces (GUIs). It is based on the idea of shifting the letters in a message by a certain number of positions along the alphabet, and looping back the the start if the shift moves a letter beyond the end of the alphabet. The Caesar Cipher was an early encryption method apparently actually used by the Emperor Julius Caesar. Hi folks, here is your Python Tkinter GUI Programming sample application to kick-start your Tkinter Skills. ![]()
