Devise your own RSA system: Choose two different primes p and q between 50 and 100. Use n = pq for your system. Give a pair of secret and public keys. Show how to encode and decode the message M = 1337 using these keys. For computing the inverse, you can use the implementation of the Extended Euclid algorithm on PlanetCalc. For computations of the kind abmodc, use Wolfram Alpha.
