What is an SSL certificate? An SSL Certificate binds together:

  • A domain name, server name or hostname.
  • An organizational identity, such as company name and location.
The depth of details bound to an SSL certificate vary based upon the type of validation performed by the Certificate Authority (CA) before issuing the SSL certificate.

An SSL Certificate is a set of one or more small data files that digitally bind a cryptographic key to an organization's details. When installed on a web server, it activates the padlock, the https protocol and allows secure connections from a web server to a browser. When installed on a service, such as API Gateway, it secures communications between systems.

Types of SSL Certificates

  • DV - Domain Validated - CABF OID
  • OV - Organization Validated - CABF OID
  • EV - Extended Validated - CABF OID
  • Misc types such as Self Signed, Individual Validated, Test, Code Signing, etc.

SSL ceriticates can also be single domain, mutiple domain, and wildcard for each type. This is really just a marketing feature as all SSL certificates support one or more domain names including wildcard domain names.
