Project: 1 One of the main challenge to use a security key algorithm such as RC4 is the key exchange. Very often the key exchange must be done offline, otherwise you run the risk of the key being eavesdropped by a hacker. Now implement Diffie-Hellman Key Exchange Algorithm in Ctt.A user will be asked to enter two prime numbers g and p, in the range 4000 to 10000. Then user A enters a number a, and user B enters a number b, both in the range of 40 to 100. Now compute the security keys generated by user A and user B respectively, and verify they are the same. Be aware that if you use the powl) function or something similar, your calculation will most likely go out of bounds. As any good program would do, your program should verify the inputs. 1. Source code (please give Ans in C++) 2. A screen shot showing the keys generated by A and B
