Topic: PSK

Hello everybody,
I wanna to use PSK in DTLS.  I chose wolfDTLS_client_method().

If use PSK, is it supposed as session key? I'm confused, how session key is produced?



Hello lili,

Thanks for your post. PSK is used to negotiate the first connection handshake. If sessions are enabled, the server will provide a session key (or ticket) that can be to quickly resume the connection without the full handshake.

Here is an example: … s-resume.c

Kind regards,
