Challenge Problems
Push your limits with challenges.
Question 1
Given the prime numbers p = 61 and q = 53, calculate N and Euler's totient function, φ(N). How does knowing these values help in an RSA encryption process?
💡 Hint: Focus on the relationships between prime numbers and their roles in encryption.
Question 2
If you have a public key (N, e) = (3233, 17) and wish to encrypt a message m = 65, how would you encrypt this message using RSA? And explain what happens if someone knows the public key?
💡 Hint: Consider the steps for encryption!
