Types of SSL certificates

These can be grouped into 3 categories based on validation:

  1. Domain Validated (DV) SSL certificates

These kinds of certificates have a least-strict level of validation. The CA or certificate authority simply verifies that the concerned domain is controlled by a valid organization to provide a DV certificate. This the cheapest way to obtain an SSL certificate and can be obtained easily via email. To verify, you can alter the DNS record associated with the domain or upload a file that is supplied by CA to the domain. This is usually an automated process.

When these certificates are granted, a padlock is shown to the left of the address window. This kind of certificate is a good option for blogs, small businesses, or portfolio sites, especially when the site is not involved in selling products and are looking just to launch HTTPS quickly.

  1. Organization Validated (OV) SSL certificates

These kinds of certificates have a modest level of verification and mostly involve a manual vetting process. The certificate authority verifies the organization and makes an application, though not very deeply. Further, they investigate more and contact the organization to make sure that it is authenticated. This is done by humans, so it costs comparatively more than DV certificates. This process may take a few days. The certificate authority issues an SSL certificate for the ownership of the domain, and information such as address is included.

When these certificates are granted, a certificate is shown with the concerned details of the website. These OV certificates are commonly used for document signing, code signing, client authentication, and S/MIME email certificates.

  1. Extended validated (EV) SSL certificates

These kinds of certificates have the strictest level of validation. The certificate authorities perform a full background check of the organization, which has asked for an SSL certificate. The authority validates the physical location, ownership, and legal existence of the company. It also ensures whether the organization is aware of the SSL certificate request and only then approves it. Due to high human involvement, it costs the most. This process may take some weeks because proper verification has to be done.

When these certificates are granted, the browser URL turns green. These certificates are usually bought by companies that handle sensitive customer data such as passwords, addresses, credit card numbers, etc. For example, banks, large enterprises, and other e-commerce stores.
