This document describes the support for performing SSH authentication with X.509 certificates. Authentication to SSH can be completed using a number of different methods. Public key, password and keyboard interactive are supported in EOS. Certificate login is a type of public key authentication in which the public key does not have to be stored on the server. Instead certificates belonging to trusted certificate authorities (CAs) are installed.

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. A user can manage certificates, keys and also multiple SSL profiles. An SSL profile is a configuration which includes certificate, key and trusted CA certificates used in SSL/TLS communication. An SSL profile configuration can be attached to another EOS configuration which supports SSL/TLS communication. Individual EOS features that use this infrastructure will document the details of using an SSL profile in their configuration.
