I'm using google translate, so sorry if it's weird English.
I didn't know how to make it compatible with x86.

But I don't think there are any users who use x86 right now, so I made a pull request for x64 only.

In actual operation, I think it is better to enable the cache as @ShadowJonathan wrote. However, I didn't write it there because I don't know if I can pull-request it due to copyright issues.

Hi, thanks for the PR! Were you able to verify that the wheel generated by the CI job result in a functional installation of the package? E.g. with a fresh python virtual env the following runs without issue?

pip install <fastecdsa windows wheel>
python -m fastecdsa.benchmark

[wakiyamap]

Sorry for the late response.

As far as I tested it, it seems to be fine.

No worries, the CI/CD jobs passing is a good start, but it would be good to verify the wheels produced actually work when installed on a fresh environment on Windows.

Thanks!
I have verified that it works locally.
Also, commands executed by CIBW_TEST_COMMAND_WINDOWS are executed in a fresh environment created by virtualenv.

Did you decide not to use wheel?

I've removed the current actions as they were still breaking intermittently and were causing pretty long running jobs (that sometimes ultimately failed) to get kicked off when adding new (non-release related) commits. I'm looking at adding them back, but only running conditionally on tagged (i.e. new release version) commits.
