This document defines the Digest and Want-Digest header fields for HTTP, thus allowing client and server to negotiate an integrity checksum of the exchanged resource representation data. This document obsoletes [RFC3230]. It replaces the term "instance" with "representation", which makes it consistent with the HTTP Semantic and Context defined in [RFC7231].
