And given that the most common OpenPGP and keyserver – and probably all – implementations are already caseless there is nothing wrong with following their lead. This isn't just about email. A large percentage of the sigs I verify are obtained though methods unrelated to smtp. Detatched sigs are quite common, and OpenPGP is or can be used when sending short messages, such as via xmpp, sip or even ss7. Using dnssec as an additional – or in many cases the only – trust path when verifying a sig can only improve things. It is not a perfect trust path of course, but it is better than nothing. Given all of that, taking (base32 (utf8 (lc (localpart address)))) and splitting it by – working with presentation format — putting a . every N chars from the right seems like the ideal plan. Unless reversibility is undesirable. I've written otherwise in the past, but only because I forgot that the OpenPGP world is caseless. And I did so because I only ever use and only remember seeing miniscule addresses when dealing with OpenPGP. -JimC -- James Cloos <[email protected]> OpenPGP: 0x997A9F17ED7DAEA6 _______________________________________________ dane mailing list [email protected] https://www.ietf.org/mailman/listinfo/dane
