Chapter 15.3, Problem 15.12CP
Explanation of Solution
Event handler:
An event handler is a module is implemented in python
- If user need a program to execute an operation at that time a particular event occurs, user must create an event handler that reply at that time of event takes place.
- Event can be pressing the key or mouse operation by the user. To deal this type of operation is considered as event handlers.
- If the defined event occurs, then call the handler function with help of object of event...

For encryption, let user input the key in Hexadecimal number, the plain text in Hexadecimal number, output the ciphertext (in hexadecimal numbers). For decryption, let user input the key in Hexadecimal number, the ciphertext (in hexadecimal numbers), output the decrypted message (Hexadecimal number). Both encryption and decryption should output the different operation results for each round like the following: For example: Round 1: E(R0) = ...... (Hex or Binary) K1 = …… E(Ro) xor K1 = S-box outputs = …… f(Ro1, K1) = ….. L2 =R1 =……. La = Ra Round 2: .....• No Encryption/Decryption libraries or functions provided by the third party are allowed.
