I am the assigned Gen-ART reviewer for this draft. For background on Gen-ART, please see the FAQ at < http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq>. This review is in response to a request for early Gen-ART review. Document: draft-ietf-tls-session-hash-04 Reviewer: Russ Housley Review Date: 2015-04-01 IETF LC End Date: 2015-04-13 IESG Telechat date: unknown Summary: Ready Major Concerns: None Minor Concerns: The most recent RFC Editor style guide places normative and informative references in top-level sections. In this document, the normative references should be Section 9, and the informative references should be in a new Section 10. Other Comments: For absolute clarity, I suggest a small addition to Section 5.1. It says: "Thus, the entire encoding of the extension is 00 17 00 00." I would add to the end of the sentence: "(in hexadecimal)". Typo correction in Section 6.3: "sent by the server/". Please replace the slash with a period.
