Here is the python code … WebActually, with RSA as you describe, there is a problem with a very small e: if you use e = 3 and encrypt the very same message m with three distinct public keys, then an attacker can recover m. But that's not really due to using a small e; rather, it is due to not applying a proper padding. Share Improve this answer Follow WebWe call N the RSA modulus, r the public exponent, and s the private exponent. The pair (N;r) is the public key. As its name suggests, it is public and is used to encrypt messages. The pair (N;s) is called the secret key or private key, and is known only to the recipient of encrypted messages. The secret key enables decryption of ciphertexts. A ... churches barry
