+Notes on TLS support:
+
+Cubemap supports TLS on output, so that you can play video on TLS
+web sites without issues with mixed content. TLS on input streams is
+not (yet) supported.
+
+TLS requires kTLS, ie., Linux >= 4.13 with CONFIG_TLS enabled. Only cipher
+suites supported by kTLS is supposed, ie., AES-128-GCM (if no such cipher
+suite is available, the connection will be aborted). If the server is restarted
+before the key exchange for a connection is completed, that connection will
+not survive the restart, unlike all other connections. (This is a TLSe
+limitation.) You can have different certificates on different ports (and
+have separate ports for TLS and non-TLS), but SNI is not yet supported.
