WebApr 13, 2024 · Asymmetric Encryption Example Alice wants to send a secure message to Bob. In order to send the message, Alice must first be able to identify how to contact Bob. With asymmetric encryption, the sender of a message (Alice) needs to know the public key of the recipient (Bob). Web1st prime p = 2nd prime q = For the algorithm to work, the two primes must be different. Public key The product n is also called modulus in the RSA method. n = p × q = 143 ( 8 bit) For demonstration we start with small primes. To make the factorization difficult, the primes must be much larger.
