azure - IoT Hub - modify complex token creation (via MQTT) -


as per heading doing this, let me explain why.

history : have done full host , client , working 100% on via .net. big our clients in field running on microcontroller (not microprocessor) has poor encryption libraries (embedded c, in particular pic). our firmware engineer guy battling hmac part of sas token generation work. other pieces of hub possible (mqtt, tls, url encoding, epoch etc) hmac sha256 struggle.

i aware of protocol gateway offered can replace gateway’s authentication provider. have sample code/guide can follow. dev guide offered microsoft seems limited or maybe im being silly , missing plot.

thanks help!

light bulb moment ;) going keep our tcp channel open , unit auth on channel. ack key (will encrypt in simpler way ;))
