In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with mod_ssl.

Key, CSR and CRT File Naming Convention

I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. This makes it easier to identify and maintain.

  • Instead of server.key, I use www.thegeekstuff.com.key
  • Instead of server.csr, I use www.thegeekstuff.com.csr
  • Instead of server.crt, I use www.thegeekstuff.com.crt

1. Generate Private Key on the Server Running Apache + mod_ssl

You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.

4. Get a Valid Trial SSL Certificate (Optional)

Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. i.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works, you can either decide to purchase it from Thawte or any other SSL signing organization.

This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.

Go to Thwate trial certificate request page and do the following:

  • Select “SSL Web Server Certificate (All servers)” under the “select your trial certificate”.
  • Do not check the PKCS #7 check-box under the “configure certificate”
  • Copy/Paste the *.csr file that you generate above in the textbox under “certificate signing request (CSR)”
  • Click on next at the bottom, which will give you a 21-day free trial certificate.
