psk authentication scheme

Asked by Dora Esmephi

Hi,

I am working with constrained devices and trying to use the psk scheme for authentication but the documentation on it is rather scarce. I am unsure, for instance, of the use of the psk hint. I also assume the scheme consist in a challenge/response dialog and would like to know more about the specifics of this challenge.

Thank you in advance

You might be better off discussing this on the mosquitto-dev mailing list so people with experience of using psk can chip in.

The documentation on psk-hint is scarce even outside of mosquitto, I suggest you read this: http://stackoverflow.com/questions/8678199/psk-hint-with-openssl

The RFC linked to there should give you all the information you need regarding the scheme.
