Greetings, I saw all problem statements in your document. Frankly I was able to do 5 of them.
Do you have any study material for this homework for the reference. I am sure I can do all questions if I get to know your study material.
I am pretty good at Cryptography. Even though I am a student, I could give you a very intuitive idea for a very affordable price. I feel you are being cheated for a very high bid. i want you to help you out i.e. the only reason why I put the minimum bid.
