--- Comment #15 from quartz <quartz...@yahoo.com> ---
nio: ok. Sorry.

As for TLS parsing, there can be a whole lot of stuff well beyond 100 bytes in
client hello, namely yet unknown extensions. TLS records proto msg length is up
to 2^14-1 bytes. Not an issue I guess.

Also, I just read that with a DHE handshake the SNI could come later and
encrypted.
https://tools.ietf.org/html/draft-rescorla-tls13-new-flows-01#section-4

So, if they have it their way, it won't be enough to look ahead the clienthello
in 1.3. But I won't bet on that delayed encrypted sni; it is paranoiac
protection because the DNS lookup just before is pretty much revealing the same
info.
