Passing a device certificate to provisioning client on linux

[mathias-nickl]

Hi there!

I am trying to provision devices with the python provisioning sdk on a linux machine. However I am not able to pass the device certificate to the provisioning client. In C# the provisioning client provides a parameter to pass the certificate via a security provider. But I am struggling to build an equivalent example in python.

How can I pass the device certificate to the provisioning device client in python?

@mathias-nickl @1-Peter unfortunately i have no satisfying answer for now:

Because the current SDK is built on the C SDK, the way to do this is to implement a custom HSM module. See:
https://github.com/Azure/azure-iot-sdk-c/blob/master/provisioning_client/devdoc/using_custom_hsm.md

This entails developing a custom HSM module in C, then rebuilding the C+Python SDK while linking to the HSM module.

we're absolutely conscious of the fact that this is not a good python experience which is why we're working on a new implementation of the SDK that doesn't rely on the C SDK (here) rather than investing in trying to patch this version of the SDK, given this design obviously doesn't work for 99% of users.

I believe we've responded to this question in #272 : the new v2 client deals with certificate a lot better than v1.
