[X2Go-User] Does x2go work with signed certificates

Hello, just wondering if X2GO has capabilities to work with signed certificates. I am currently using x2go to connect to a centos 6.1 server with essentially an interface to mysql. The connection is done through public and private keys, with authorised key file(public key) on the users home directory on the server. I want to switch to signed certificates, will x2go support this?

I use vault by hashicorp to sign my certificate after public key is sent to it, then I authenticate using private key and signed certificate to the host. The command is: ssh -i signed-cert -i ~/.ssh/id_rsa username@ip_address
