Trusted CAs are usually listed on the host The client can then check that the server has a (CAs) certificates to issue certificates, which keeps the client-side configuration moreĪ server certificate using its private key. Servers usually rely on Certificate Authorities If the server is a third-party web service, such as a web browser or email app, it's more difficult to know when to update the client app. The server configuration change necessitates updating the clientĪpp. However, servers might use key rotation to change their certificate's
