SLSA + Python Notes

Created example project: https://github.com/sethmlarson/python-slsa-release-test

Python doesn't have a specific builder yet. Only have source attestation using the generic builder. Used: slsa-framework/slsa-github-generator/.github/workflows/generator_generic_slsa3.yml

Attestation "subject.name" is taken as input from sha256sum, so check the output of that to ensure it's what you want (ie package.tar.gz vs dist/package.tar.gz) For this I had to include a cd dist/ && before the sha256sum * call. Not sure where this matters though?

Success:
