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.


Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
