Matrix requires valid certificates for federation with other servers from
version 1.0 onward. If the FreedomBox server already has LE cert and private
key, copy them into /etc/matrix-synapse
- Add certificate renewal hooks for Matrix Synapse. Reusing the certificate
renewal mechanism built for ejabberd with matrix-synapse as well. One notable
difference is that Matrix Synapse doesn't support switching the domain name or
dropping the Let's Encrypt certificate.
- Use self-signed certificate if there is no LE certificate. Matrix Synapse
server startup fails if the files homeserver.tls.crt and homeserver.tls.key
are missing.
- Copy Apache's snakeoil certificates to /etc/matrix-synapse when LE
certificates are not available. Prefer LE certificates if available.
- Display warning if no valid LE certificate is found.
