Certification Authorities

There are 2 types of certification authorities:

1. Certificates issued by widely accepted public certification authorities - These are certificates issued by public companies (such as GlobalSign, Comodo, etc.). The issuance of a certificate signed by such a certification authority is a paid service.
2. Self-signed certificates - These are certificates issued by a private (personal) certification authority. A private certification authority in a company is usually maintained by the IT department. Certificates issued by such an authority can be used for various purposes, they are free and can be created independently. Large companies sometimes create their own private certification authority infrastructure and issue certificates signed by it.
