Also known as: RFC 8315
A header scheme, standardized in RFC 8315, letting a poster prove authority to cancel or supersede an article. The original carries a hash commitment, and a later cancel carries the matching secret for servers to verify. It replaces the classic arrangement in which any party could forge a cancel for anyone else's article, and it explains why many servers now discard unauthenticated cancels.
