For certificates defined by the domain number, the types are single, multidomain, and wildcard. Certificates are processed by a Certificate Authority (CA), which is software designed specifically for running and granting these certificates.įor encryption and validation certificates, there are domain, organization, and extended validation. They each have three classifications, and can be applied for on the SSL website. The umbrellas that SSL certificates fall under are encryption and validation, and domain number. There are three types of certificates you can earn depending on the SSL you obtain. SSL certificates are categorized by the level of validation and encryption provided OR the number of domains or subdomains under the certificate. Having one means that the details you are collecting are private and ensures the customer that when they see that padlock and their privacy is safe. This is done using an encrypted link that connects the server and browser.Ĭompanies that request personal information from a user, such as an email address or payment information, should have SSL certificates on their website.
