What I Did to Install an SSL Certificate When Building a Website for a Client
Overview
While building a website ordered by a client, I needed to install an SSL certificate. This post summarizes the steps I followed at that time.
Prerequisites
Since free SSL or self-signed SSL certificates raise security concerns, I decided to obtain a certificate from thawte, which issues SSL certificates with a high market share.
I also obtained the client’s approval regarding the cost.
thawte is the world’s second largest certificate authority by market share, providing various server authentication and code signing certificates to customers around the world.
ToDo
- Check the domain owner information with WHOIS
- Confirm the DUNS number held by the client
- Issue a CSR
- Apply for SGC Super Certs
- Install the SSL certificate
Steps
1. Check the domain owner information with WHOIS

WHOIS displays the owner information for the domain you search.
Save this information.
It will be used later when issuing the CSR.
2. Confirm the DUNS number held by the client

3. Issue a CSR

4. Apply for SGC Super Certs

5. Install the SSL certificate
