Thanks. Will fix it.

There are some folks who believe that we should align our crypto-mathematics with how its done in IS-IS and RIP (https://www.ietf.org/proceedings/08nov/slides/ospf-5.pdf). However, the other argument is that though it did make a trifle bit of sense in doing it for IS-IS and RIP, it makes none, none at all, for OSPF. 

It is only this that's stalling the document from moving ahead which is otherwise ready for WG LC.

Cheers, Manav
