Dear Robert Moskowitz,

To follow up on the issue of using RUST code from/together with Python:

The easiest alternative that we have found is using the functionality
offered by PyO3, https://pyo3.rs/v0.21.1/. The user guide includes a
step-by-step example of how RUST functions can be exported and used within
a Python environment.

Our current RUST demo implementation is just printing the c509-encoded
certificate to screen, a functionality which is easy to wrap but perhaps of
limited usefulness. The ongoing work to provide also a c509 to X.509
converter will not bring the implementation beyond demo status, but we
intend to format it with an API that would make it easier to test in
different environments, for instance through a PyO3 wrapper.

Best Regards

Joel Höglund
