Signature-based Integrity [1] relies on user agents properly handling `Unencoded-Digest` headers [2] which deliver a server's assertions about the integrity of a given response's body. This patch extracts the relevant algorithms from [1], spelling out the processing model for the header, and verifying response integrity at the end of Main Fetch, alongside SRI's existing check. This is one step of the Signature-based Integrity upstreaming work detailed in [3].

Hey folks! I'd like to start upstreaming signature-based integrity checks; this seemed like the simplest self-contained place to start. Assuming folks are on board, I'll file implementation and MDN bugs, and put up more PRs against SRI and CSP. |
