Could you show the step in details

This question involves decoding using a brute force decryption mechanism. Brute Force decryption: Brute force is a trial-and-error method used by application programs to decode encrypted data such as passwords. Consider the following table: Using Brute Force, you need to keep shifting until a readable message is found. Our problem Consider the following secret message: IBA THU PZ UVA THKL MVY KLMLHA H THU JHU IL KLZAYVFLK IBA UVA KLMLHALK It has been encoded with a secret shift key that is not provided in this question. a) What is the total number of shifts in a Worst-Case Scenario. b) Decode the cipher message, writing it in lowercase letters. c) Encode the obtained text message using a left shift and the shift key value is found from GCD (1701,3768). d) Show all the details of your work
