Automatically Generate Unique IoT Device Certificates Using Prevalidated Domains

Introduction:

SSL.com provides a domain prevalidation capability that speeds up the process to issue certificates. The process is extended to all subdomains to the left of the validated domain.

Why is This Important:

SSL.com, in support of industry standards, will not issue an SSL/TLS certificate for a domain and its subdomains until it has been validated. Prevalidating a domain satisfies this requirement while speeding up the process.

With the growth of IoT devices on the internet, the challenge of properly securing thousands of devices can be overwhelming. The ability to prevalidate the domain not only speeds up the certificate issuing process but also provides a consolidated portal to manage large quantities of certificates.

How to Prevalidate a Domain:

  • Sign on to your SSL.com account.
  • Proceed to the Domains Tab and click to open.
  • You will find a secondary link titled [learn about pre-validating domains]

  • This references the process to follow.

If you choose to use the command line, an example sequence is here:
