Challenge Problems
Push your limits with advanced challenges
You are given the public key (N = 221, e = 15) and a ciphertext (c = 38). Calculate the original message m assuming it was encrypted with the RSA algorithm.
💡 Hint: Focus on factoring N first and then use the steps of RSA.
Create an RSA scenario with your chosen large primes: p = 61, q = 53; demonstrate encryption of the message 'Hello' represented as an integer.
💡 Hint: Represent the message well and remember to apply the proper RSA formula.
