Whether its a blog or a business application, you certainly need an SSL certificate to tighten the security of your application. SSL are of two categories: paid or free. The free certificates is normally a domain validated certificate, while the paid ones are either organization or extended validated certificates. There are some types that I need to document the category of certificate being used by an organization.

Below are ways I differentiate between them:

Extended validated: Instead of just a padlock preceding the address, modern browsers also displays the name of the company the domain was issued to.

Organization validated: Click to view the certificate information, if you see the displayed value for policy identifier as 2.23.140.1.2.2, then its OV

Domain validated: Click to view the certificate information, if you see the displayed value for policy identifier as 2.23.140.1.2.1, then its DV

How do you differentiate between the different types of certificates???
