We have attempted to contact various chairs, but given the challenges of mail volume, spam, and centralization of mail providers, I worry that the lack of response to date from them, that they are not even seeing the emails. For instance, I've found with IETF lists that I can't use gmail the way I normally do, and have to send differently. > Finally, we would like advice from Dispatch on the best way to register > our > > cryptographic-focused CBOR tags used in Envelope with IANA, namely > whether > > we should do so now, or whether we should wait for later in the IETF > > process. > > I've followed the CBOR work some, and in general there's no shortage of > tags. So registering it early is likely to be OK.

We have listed our requests for them in our I-D under IANA considerations https://www.ietf.org/id/draft-mcnally-envelope-00.html#name-iana-considerations However, in particular with the core envelope tag, having it be even smaller could be quite advantageous, as some of our developers are using very constrained silicon where every byte counts. As the design of envelopes is "envelopes of envelopes," there can be quite a few of these tags. This would require support from a working group (or another standards org, which may also be possible). OTOH, if further work on Gordian Envelope is likely to change the > details of the specifications of your tag, you aren't violating the > rules if you register it FCFS; few will care if you update the > definition or abandon it entirely.

We have a a short video introducing our concepts at https://www.youtube.com/watch?v=OcnpYqHn8NQ, and you'll see some paper-world examples. I've been seeking a CC-BY photo of a letter locking envelope to add to our imagery ;-) -- Christopher Allen
