WebThe RSA algorithm uses the following steps to generate the public and private keys. Choose two prime numbers, p and q. We must try to take large prime numbers to ensure the high security of our data. Compute the modulus for encryption and decryption denoted by n, equal to the product of p and q. Hence, n = p * q.
