Server certificate stores

[MaciejBober]

Hi everybody,
I am using the command line tools to connect to a Prosys OPC UA simulation server, using certificates for a secure connection(e.g. by using uasubscribe). My question is, is there a default store/directory where the server certificate would be saved/stored? I can see the client's certificate in the simulation server app and in the logs I see that the server certificate is passed but I can't find any place that the server certificate would be stored to see if it's trusted or rejected etc.
