This document describes a mechanism for creating, encoding, and
verifying digital signatures or message authentication codes over
components of an HTTP message. This mechanism supports use cases
where the full HTTP message may not be known to the signer and where
the message may be transformed (e.g., by intermediaries) before
reaching the verifier. This document also describes a means for
requesting that a signature be applied to a subsequent HTTP message
in an ongoing HTTP exchange.

This document is a product of the HTTP Working Group of the IETF.

This is now a Proposed Standard.

for improvements.  Please refer to the current edition of the Official
