SSL SSlstream Support in .Net Compact Framework

Question

Im working on WinCE 2013 and want to use mqtt protocol with SSL/TLS. But it seems like that the SSL StreamCLass is not supported in .Net CF3.9. Could anyone please let me know if there is anyway the SSL/TLS can be enabled in .NCF3.9 for communication. I want to use the SSL Stream class and the

using System.Net.Security;
using System.Security.Authentication;

but couldnt do so...

Answer 1

看看： https ://m2mqtt.wordpress.com/ 这是一个随时可用的 MQTT 实现，如果它不符合您的需求，您至少可以看看 SSL 在 .NET CF 中是如何实现的。

Answer 2

In order to enable SSL/TLS on M2Mqtt you need to define SSL symbol. For example, if you see the Net MF 4.3 project file ( https://github.com/eclipse/paho.mqtt.m2mqtt/blob/master/M2Mqtt/M2Mqtt.NetMf43.csproj ) there is this section :

<DefineConstants>DEBUG;TRACE,MF_FRAMEWORK_VERSION_V4_3,SSL</DefineConstants>

As you can see there is the SSL symbol. It enables the build with SSL support.

I added OPENSSL suppport for Compact Framework 2.0 / 3.5 / 3.9 in M2MQTT library. Check https://github.com/bpastore/paho.mqtt.m2mqtt/tree/dev

I am having the same issue in NETCF3.5 and when I tried to open this link for the solution it is now gone:

I am running WEC7 with netcf3.5 but I need to add encryption. Anybody help on this???
