Hi @a8Chcx.,
I apologize for any inconvenience this may cause, but we do not have examples of an HTTP server with digest authentication for Kinetis K66.
My recommendation would be to start with the httpsrv_freertos example. You can find APIs in the httpsrv folder that can assist with the implementation.
Please note that the implementation will need to be done on your end.
Best Regards,
Pablo
