Hello,

I have reviewed draft-ietf-tls-chacha20-poly1305-04 as part of the
Operational directorate's ongoing effort to review all IETF documents
being processed by the IESG.  These comments were written with the
intent of improving the operational aspects of the IETF drafts. Comments
that are not addressed in last call may be included in AD reviews during
the IESG review.  Document editors and WG chairs should treat these
comments just like any other last call comments.

This I-D leverages the existing definition Of Chacha20 and Poly1305 as
per RFC7539 and uses those to define new TLS ciphersuites.

I believe this document is ready for publication.

There are no real operational considerations in this document: the new
ciphersuites are merely IANA codepoints for TLS; TLS itself is
crypto-agile and can dynamically negotiate mutually matching
ciphersuites with TLS clients. This allows an easy step-up to these new
ciphersuites where they are available.

I did not even find a single nit!

Greetings,

Stefan Winter
