Now that we've rechartered, we can adopt this document, pending working group
approval.

John Mattson presented about CBOR Certificates

Issue #84 - Should a tag be defined?
A tag was recently added to the draft

Michael Richardson prefers the CBOR Sequence mechanism
Carsten: +1
This means that we would use draft-ietf-cbor-file-magic
Uri Blumenthal supported this position
Michael Richardson will create a PR doing this

Issue #68 - Using same encodings for CRLs

Michael Richardson said that CSRs are more important than CRLs

Uri talked about the disconnected case

Göran asked what would go into this draft and what would go into a separate
draft

There was a discussion on using IETF-standard mechanisms versus proprietary
mechanisms

3. ~~IANA registrations policies~~

4. AOB

We will schedule the next interim meetings for 1/2 hour later than this one to
avoid a conflict with core interim meetings.
