# List of allowed TLS fingerprints for this server to publish along

# with the signing keys for this server. Other matrix servers that

# make HTTPS requests to this server will check that the TLS

# certificates returned by this server match one of the fingerprints.

#

# 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 '='

# or by checking matrix.org/federationtester/api/report?server_name=$host

# CPU affinity mask. Setting this restricts the CPUs on which the

# process will be scheduled. It is represented as a bitmask, with the

# lowest order bit corresponding to the first logical CPU and the

# highest order bit corresponding to the last logical CPU. Not all CPUs

# may exist on a given system but a mask may specify more CPUs than are

# present.

#

# For example:

#    0x00000001  is processor #0,

#    0x00000003  is processors #0 and #1,

#    0xFFFFFFFF  is all processors (#0 through #31).

#

# Pinning a Python process to a single CPU is desirable, because Python

# is inherently single-threaded due to the GIL, and can suffer a

# 30-40% slowdown due to cache blow-out and thread context switching

# if the scheduler happens to schedule the underlying threads across

# different cores. See
