Assignment:
Consider the RSA encryption system given by p=43,q=59, and e=13
i) Find d such that ed ≡ 1 (mod (p-1)(q-1))
ii) Decode the message : 1552 2069 1178 1637 1975
Using the convention A = 00, B = 01, …, Z = 25
Provide complete and step by step solution for the question and show calculations and use formulas.
