  1. Create Certificate with existing Private Key. Openssl req -key priv1024.pem -new -x509 -days 365 -out domain.crt. Extract Public Key from Cert as PEM file. Openssl x509 -pubkey -noout -in stackexchangecom.crt pubkey.pem. Strip the Generic Header and Footer.
  2. If you would like to obtain an SSL certificate from a certificate authority (CA), you must generate a certificate signing request (CSR). A CSR consists mainly of the public key of a key pair, and some additional information. Both of these components are inserted into the certificate when it is signed.
