Security Certificates Overview
How Certificates Work
X.509 certificates are a security technology that assists networked computers in determining whether to
trust each other.
● A single, centralized certificate authority (CA) is established. Typically, this is either an enterprise’s IT
department or a commercial certificate authority.
● Each computer on the network is configured to trust the central certificate authority.
● Each server on the network has a public certificate that identifies it.
● The certificate authority signs the public certificates of those servers that clients should trust.
● When a client connects to a server, the server shows its signed public certificate to the client. Trust
is established because the certificate has been signed by the certificate authority, and the client has
been configured to trust the certificate authority.

System
X.509 certificates come in several forms (encoding and protocol). The following table shows the forms that
