WebThe RSA algorithm uses prime numbers to generate the public and private keys. The following are the steps involved in RSA Encryption: Choose two prime numbers, p and q. Calculate n = p * q. Calculate the totient of n, phi = (p-1) * (q-1). Choose an integer e (1 < e < phi) that is co-prime with phi (i.e., gcd (e, phi) = 1). WebIt isn't necessary to have a top-level section marker, so you can just remove that first line, and then it will work fine for both generating requests or certificate. $ openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt -extfile config.cnf.
