Hi Everyone,

Following the discussions around draft-bartle-tls-deprecate-ffdh and
draft-aviram-tls-deprecate-obsolete-kex, and after consulting the chairs,
we have merged the two drafts into draft-aviram-tls-deprecate-obsolete-kex
<https://datatracker.ietf.org/doc/draft-aviram-tls-deprecate-obsolete-kex/>.

The merged draft prescribes the following:
1. RSA key exchange is a MUST NOT.
2. Non-ephemeral finite-field DH is a MUST NOT.
3. Non-ephemeral ECDH is a SHOULD NOT.
4. Ephemeral finite-field DH (DHE) is a MAY, only when fully ephemeral, and
only using a well-known group of size at least 2048 bits.

We added greater justification for point 3
<https://www.ietf.org/archive/id/draft-aviram-tls-deprecate-obsolete-kex-01.html#name-security-considerations-2>
above to address concerns previously raised on the list.

We'd love to hear your thoughts.

best wishes,
Carrick and Nimrod
