OpenSSH with X509 certificates HOW TO

In this post I will explain how to test a connection with OpenSSH using PKIXSSH fork from Roumen Petrov.

The full process followed to test a SSH connection between a client and a server machine using X509 certificates will be detailed. To make the test we will use a third machine, that we will call control machine, machine that will act as a “Certification Authority”, which is the entity that will validate the authenticity of the certificates presented by the user who wants to make a connection and by the destination server.
