First, this is a proof of concept of the implementation. It is stable and we are actively using it in our current project. However, we believe it is necessary to contribute these changes upstream, as they affect two projects:
azure-iot-sdk-pythonto support PyOpenSSL andpaho.mqtt.python.Reference/Link to the issue solved with this PR (if any)
Description of the problem
There is currently no straightforward way to use a TPM with the azure-iot-sdk-python.
Description of the solution
This PR leverages PyOpenSSL to provide a custom context with OpenSSL PKCS#11 support, enabling the use of a TPM. This requires changes to both the azure-iot-sdk-python and paho.mqtt.python to support the PyOpenSSL context.
