Hi, i got paho java client working with a mosquitto broker without ssl.

I am trying to set the psk-identity and psk values in the paho client but i am failing.
Using the mosqquitto_sub with --psk-identity and --psk works very well.

I assume i need to use some sort of sslsocketfactory but i havent found any good example to use (very new to ssl also).

Any help or pointers are greatly appreciated.

Thank you.

Hi Johan, apologies for taking so long to respond but I don't always keep an eye on the web forums as much as on the mailing list.

Does this help at all?

Hi Tushar, did you see the reply to the same issue you reported on the Github Gist posted by Sharon?

https://gist.github.com/sharonbn/4104301

It sounds like you could have a corrupt certificate file or an issue with the platform you are on?

Hi Tushar, did you see the response Sharon posted to this same issue you reported against his original Gist?

https://gist.github.com/sharonbn/4104301

It looks like you may have a corrupt certificate or an encoding issue?

What platform are you on, and what JVM?
