When attempting to run the "provisionconfig" CLI tool on macOS High Sierra, an "Error initializing ctypes" error is displayed and none of the provisioning artifacts - private key, certificates, or configuration - are created. Here a sample output from running this command:
› python -m dxlclient provisionconfig sample myeposerver client

oscrypto._ffi.FFIEngineError: Error initializing ctypes
I saw the error both with Python 2.7.10 and 3.7.0. I was also able to reproduce the issue with two different SSL versions - LibreSSL 2.2.7 (default SSL installed with High Sierra) and a Homebrew-installed OpenSSL 1.0.2p (14 Aug 2018). In each case, I had the latest oscrypto release, 0.19.1, installed.
This was raised as an issue to the oscrypto project, wbond/oscrypto#22. The issue has been fixed but has not been delivered in a new release of the oscrypto library yet.
In each case, I was able to perform the provisionconfig command successfully by performing either (or both) of the following:
Run pip install cffi.
Run pip uninstall oscrypto, followed by pip install git+https://github.com/wbond/oscrypto@af778bf.
oscrypto version af778bf was the head of the master branch at the time I ran the test.
A separate PR which would include cffi as a formal project dependency, #35, has been proposed.
The text was updated successfully, but these errors were encountered:
