Challenge Problems
Push your limits with advanced challenges
You are given N = 221 and e = 5. Factor N, find ϕ(N), and determine d if you need d to be coprime to ϕ(N).
💡 Hint: Use the Euclidean algorithm to find d.
Explain why using larger key sizes (e.g., 2048 bits) enhances RSA security. Include potential vulnerabilities of smaller key sizes.
💡 Hint: Consider how computational power affects cryptotherapy.
