A well-known URI for publishing ECHConfigList values from a web server. The Internet draft is an IETF TLS WG draft specification.
This is the local copy.
wkech-03.sh is a bash script that implements (most of) the draft. That has a bunch of dependencies, and is a work-in-progress, so don't use it - it's for testing and not that well tested. That is used for the defo.ie ECH deployment.
[wkech-04.sh] is a version that uses our
ECH-enabled curl
rather than openssl s_client. Plan is to replace the above with that
soonish.
(ECH used be called ESNI, hence the repo name.)
