Step 2: Generate the CA private key file. The certificate snap-in in mmc can create public/private key pairs. 2, Create a server. OpenSSL Convert P7B. openssl req -key [PVK_file] -new -out [CSR_filename] –config [your_openssl. /something-CA. You can use the OpenSSL toolkit to generate a key file and Certificate Signing Request (CSR) which can then be used to obtain a signed SSL certificate. OpenSSL also supports converting. Keep the password safe. Since the public key stays the same on a simple renewing, this fingerprint will be the same too.
