MQTT SSL Support

[noelgeorgi]

@hek @Anticimex is there any way to add SSL support for MQTT client on nodemcu(esp8266). I know that esp8266 supports SSL(from node-mcu custom builds http://nodemcu-build.com/). I am using domoticz as controller and it already has MQTT SSL support. I am planning to run domoticz on my VPS so SSL support for MQTT is required.

No idea. I have only looked at security from a node2node node2gw perspective. Not controller2gw. That is too controller specific to be generalized efficiently. But there probably exist ssl libs out there which you could look at.

Thanks for the reply but the controller already supports ssl, its the mysensors eso8266mqtt client that doesnt support ssl!!!

We're using the pubsubclient library for the MQTT communication:
https://github.com/knolleary/pubsubclient

From what I can tell it doesn't support the WiFiClientSecure at the moment. But I could be wrong.. just did a quick search among their issues on github.

@noelgeorgi Yes, but I am not doing controller specific adaptations to the library for signing/encryption. So your ssl feature in your specific gw is specific to you (and all others who happen to need ssl for MQTT).

Thanks for the fast replies. This is the only forum i have seen with the fastest replies. @hek @Anticimex there really exist an mqtt library for esp8266 supporting SSL, any way to change to this: https://github.com/tuanpmt/esp_mqtt

Please, go ahead and create your own GatewayTransport variant. Will probably be appreciated by others as well.

Already work in progress, esp8266 2.1.0 library added support for having ca certificates in SPIFFS memory, not enough documentation on using it....

https://github.com/knolleary/pubsubclient will not support for SSL. https://github.com/knolleary/pubsubclient/issues/23

[noelgeorgi]

you just have to change WiFiClient client; to WiFiClientSecure client;

finally succeeded in implementing ssl for MQTT with esp8266!!!!!!! will post in Development...... http://forum.mysensors.org/topic/3385/ssl-support-for-mqtt-on-esp8266

Did you have any success to implement SSL support to the mqtt broker?
