Automatic certificate management provides support for retrieving signed x509v3 certificates from a server under the Enrollment over Secure Transport (EST) protocol, described in RFC 7030. The feature provides only EST client capabilities.

This is an infrastructure that provides management of SSL certificates, keys and profiles. SSL/TLS is an application-layer protocol that provides secure transport between client and server through a combination of authentication, encryption and data integrity. SSL/TLS uses certificates and private-public key pairs to provide this security.
