How to create username and password in mqtt mosquitto programatically in C#

[abhinav sharma]

I am new to mqtt mosquitto.i want to create some user in mosquitto programatically in C#, so that when i create topic only assigned users can subscribe to that topic.

• can i create x509certificate ,so that my device will install these certificate and i can authenticate at the time of subscribe message.if possible then how.
  
• if x509certificate is not supported by mqtt mosquitto so how authentication will work(by creation of user only or there is some other mechanism).
  
• when i am using this _client = MqttClientFactory.CreateClient(address, obj.ClientID,"username","password"); then broker connection error occur.
  
• with one topic how much user can be created

Thanks in advance
