-# Synapse automatically adds the fingerprint of its own certificate
-# to the list. So if federation traffic is handled directly by synapse
-# then no modification to the list is required.

-# If synapse is run behind a load balancer that handles the TLS then it
-# will be necessary to add the fingerprints of the certificates used by
-# the loadbalancers to this list if they are different to the one
-# synapse is using.

-# Homeservers are permitted to cache the list of TLS fingerprints
-# returned in the key responses up to the "valid_until_ts" returned in
-# key. It may be necessary to publish the fingerprints of a new
-# certificate and wait until the "valid_until_ts" of the previous key
-# responses have passed before deploying it.

-# You can calculate a fingerprint from a given TLS listener via:
-# openssl s_client -connect $host:$port < /dev/null 2> /dev/null |
-#   openssl x509 -outform DER | openssl sha256 -binary | base64 | tr -d '='
