that is the value of Internet Drafts that many of us IETFers have 
figured out.  draft versions can just keep on going and the tools will 
take you to the current draft.  IDs have become neat working documents, 
though there is more github work coming along.  More workgroups are 
doing requirements docs that will never be published as RFCs; they will 
stay as IDs.  Much better source of why did the wg do? than plow through 
the old mailing list archives.  The IESG is actually encouraging such a 
use of IDs.

I will take a look at this.  It did not come up in my google searches a 
year ago.  Guess just not asking the right question or github is 
protected from google...

In testing situations I have been in, intermediate CAs, revocation, the 
like are needed.

Plus getting more interest in 802.1AR certs with vendors (can't get 
certs to test out my product design).

I will be interested to see how you handle DER, as I found cases where 
the command line was broken.  Read my caveat section.  In some cases you 
have to make the file in PEM then convert to DER.  Plus there is no DER 
way to handle cert chains as was discussed here a year ago.  So I will 
be interested to see how you handle cert chains non-PEM.

I will take a look.

Nice.  See https://github.com/rgmhtt/draft-moskowitz-ecdsa-pki

I am right now adding an algorithm variable to support ed488.

This actually does not work right with 1.1.1-pre9, as PR 6901 did not 
make that build, so I have to do my command and .cnf patches still.  If 
I publish prior to 9/11 (2nd day of Rosh Hashana, so I won't be doing 
any work the beginning of next week), I will have to include text (that 
a later draft version will remove) about this caveat.  Given what I have 
to do this week, I will probably not publish until middle of next week.  
IEEE 802.1 will be meeting in Oslo, so I will be working remotely to get 
a PAR going to rev 802.1AR to support EDDSA based on my work.  Now there 
is a standards org that has real challenges with advances like this.  
802.1AR-2018 only supports RSA and ECDSA p256 and p384.
