Hi,

Thank you for the draft.

As said, I would love to have this kind of document.

In TLS 1.3, multiples steps are required to derive the AEAD secrets.
Without a step-by-step example, implementors need to (i.e. I had to)
struggle to figure out what went wrong.

I also believe that the document should be put up at some location
where people trying to implement TLS 1.3 can find easily. And as a
novice myself, RFCs would be where I would search first.

> Abstract:
>    Examples of TLS 1.3 handshakes are shown.  Private keys and inputs
>    are provided so that these handshakes might be reproduced.
>    Intermediate values, including secrets, traffic keys and ivs are
>    shown so that implementations might be checked incrementally against
>    these values.
