Hello,

It's not done yet; it probably has errors; it definitely has omissions; it's still riddled with "XXX"s everywhere… but here's a work-in-progress draft proposal for migrating our link protocol(s) to use TLS 1.3:

https://gitweb.torproject.org/user/isis/torspec.git/log/?h=tls13

It's not quite ready for a whole bunch of feedback yet, since I'm still reading through all the specs and writing the proposal. However, if you're super knowledgeable about TLS 1.3 and have opinions or ideas or see a mistake/misunderstanding somewhere, please feel free to share! Thanks!

Best regards,
