[Question] TLS PSK Authentication

[nolwad]

Is this library compatible with PSK Authentication? The MQTT server that my company has is set up for PSK based authentication and encryption and as such, I believe it doesn't use a root certificate, but rather a psk identity and key to be passed in when connecting as a client. As an example, when connecting from the terminal I'd put in this command to subscribe:

mosquitto_sub -h 160.36.60.20 -t 'test' -u username -P password -p 8883 --psk-identity user --psk 123456789

It works fine, but with the Arduino I can't input the psk information. Is there a way to do it with this library, or does psk need to be on the Arduino's crypto chip itself?

The code must be sending the server IP, topic, username, password, and port. Is there a way I can force my code to send my psk information along with it?
