The following errata report has been submitted for RFC8617, "The Authenticated Received Chain (ARC) Protocol".
-------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7910 -------------------------------------- Type: Technical Reported by: Steffen Nurpmeso <[email protected]> Section: 4.1.2 Original Text ------------- arc-ams-info = instance [CFWS] ";" tag-list arc-message-signature = "ARC-Message-Signature:" [CFWS] arc-ams-info Corrected Text -------------- arc-ams-info = instance [FWS] ";" tag-list arc-message-signature = "ARC-Message-Signature:" [FWS] arc-ams-info Notes ----- The RFC claims in 4.1.2 The AMS header field has the same syntax and semantics as the DKIM- Signature field [RFC6376], with three (3) differences: but the three differences do not denote the FWS->CFWS change. CFWS is to be parsed very differently than FWS, given its potentially infinite recursion behaviour, and the possibility to use quoted-pair's, ie, "escapability", something which (like almost RFC 5322 as such in practice) the DKIM RFC circumvents by using VALCHAR, a corruption of VCHAR as of RFC 5234. In effect neither of these standards adhere to neither of RFC 5322 (plain atext, quoted-string, quoted-pair) nor RFC 2045 (K=V without whitespace; quoted-printable or base64 for 7-bit clarity etc etc), making them very hard to parse, to mention my humble opinion. Instructions: ------------- This erratum is currently posted as "Reported". (If it is spam, it will be removed shortly by the RFC Production Center.) Please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party will log in to change the status and edit the report, if necessary. -------------------------------------- RFC8617 (draft-ietf-dmarc-arc-protocol-23) -------------------------------------- Title : The Authenticated Received Chain (ARC) Protocol Publication Date : July 2019 Author(s) : K.
