[Curdle] SSH/QUIC draft

[denis bider <[e-mail]>]

Hey everyone,

I noticed that QUIC - a secure, multi-stream replacement for TLS over TCP -
is close to standardization at the IETF.

For at least 7 years now, I've been pondering that TCP is a poor transport
for SSH and should be replaced by UDP. However, it has always looked like a
lot of work.

Now, most of the work seems to have been done by QUIC. There's also a nifty
implementation by Cloudflare which has a liberal BSD license and seems very
suitable to adaptation for SSH. It nicely separates the TLS handshake so it
can be pulled out while the TLS cipher suites are kept: this makes it easy
to replace the TLS handshake with an SSH-friendly key exchange.

With this inspiration, I wrote an SSH/QUIC spec which fixes all of the
architectural problems I can think of in SSH from experience over the years:

The HTML version of the draft has the most reader-friendly presentation - I
suggest using that one.

I wonder if anyone is interested in implementing this. I'm seriously
considering it, probably based on Quiche. I've forked it already, but I
haven't yet done real work:
