This is the OPS-DIR review of draft-moonesamy-sshfp-ed25519 . The version that I reviewed is http://www.ietf.org/id/draft-moonesamy-sshfp-ed25519-01.txt .   The OPS-DIR reviews are focused on the operational and manageability aspects of the documents using RFC 5706 as guidance. Please consider these comments together with the other IETF Last Call comments.   This document  Informational RFC status. It extends the IANA "SSHFP RR Types for public key algorithms" registry by adding an algorithm number for Ed25519. There are no manageability or operational implications related to this document. None of the checklist items listed in RFC 5706 apply.   A number of nits will be easily corrected by the RFC Editor:   -           [RFC6594] is not referred in the document in the bracketed format, resulting into a ‘reference not used’ error -           [FIPS180-4] is listed as a Normative Reference but not used -           Ed25519 and ED25519 are inconsistently used in the document. I recommend settling on one way to write it.   Regards,   Dan
