Some experience


Code signing is coming to the Python packaging ecosystem, in the form of Sigstore: individual package maintainers and users will be able to sign for and verify the authenticity of their Python packages, respectively, without the historical and technical baggage of PGP.

This talk will serve two purposes: (1) as a introduction to Sigstore, and its security model, to Python developers, and (2) as a technical overview of ongoing efforts to integrate Sigstore into Python packaging.

Attendees will be introduced to the cryptographic fundamentals of codesigning, how Sigstore accomplishes codesigning without long-term key material (a critical downside to PGP), as well as the guarantees they can derive from strong codesigning in the Python packaging ecosystem. They'll also be introduced to the technical aspects of Sigstore's integration into Python packaging, including a peek behind the scenes at the standardization process and other foundational efforts required to introduce a new codesigning format to one of the world's largest packaging ecosystems.
