(Reply-to is > set to the kitten WG list.) This is a helpful document. Herewith a few comments. §2 For the SCRAM-SHA-256/SCRAM-SHA-256-PLUS SASL mechanisms, servers SHOULD announce a hash iteration-count of at least 4096. Because (per RFC 5082) it is mandatory for the server to announce a hash iteration-count, I'm wondering if that could be better expressed as: For the SCRAM-SHA-256 and SCRAM-SHA-256-PLUS SASL mechanisms, the hash iteration-count announced by a server SHOULD be at least 4096. §3 It might be helpful here (or in the introduction) to describe why we need these mechanisms, i.e., presumably they might have stronger security properties or greater predicted longevity than the SCRAM mechanisms based on SHA-1. Nits: §1 mechanism are defined -> mechanisms are defined §4 I doubt that we need RFC 2119 language in the form. Peter
