The kernel, along with several other important projects, continue to use fully decentralized means of collaboration that is based on sending patches and code reviews via email. Existing end-to-end email attestation mechanisms, such as PGP/MIME or S/MIME, have important drawbacks that limit their usefulness when it comes to attesting structured content like patches. Patatt is a small library that adopts the DKIM standard to introduce end-to-end cryptographic signing of patches. When incorporated into maintainer tools like b4, it allows for full end-to-end attestation of code, as well as public keyring management via the git repository itself.
