1. ASCII code is a fixed-length coding scheme. Using the 7-bit ASCII code table [3] or any other references, find the corresponding code for the first letter of your first name, add 1 to the left position of the most significant bit (MSB), for example your name is Xxxx Ssss, the first letter is X, its ASCII is 1011000, adding 1 to the left position of MSB yields to 11011000. These bits sequence is the message that you will encrypt using the Simplified DES algorithm.

2. Based on the understanding of Q3 of Bart B, use the 10 bits password (1100110010) to generate the keys (K1 and K2).

Your answer should be detailed, you should show each output of each step of the algorithm besides the final answers.

3. Based on the understanding of Q4 of Bart B, use the generated keys of Q2 - Part C to encrypt the message of Q1 - Part C using the Simplified DES algorithm.

Your answer should be detailed, you should show each output of each step of the algorithm besides the final answer.
