    prime factorization. Assume that zoy wants to send a message to sam. sam generates public and private keys using RSA Encryption algorithm and publishes the public key (n=4717, e=19). zoy has a secret message M to send. Nobody knows the value of M. She encrypts the message M using the public key and sends the encrypted message C=1466 to sam. alex is an intruder who knows RSA and prime factorization well. She captures the encrypted message C=1466. She also has...
