Wowza StreamLock AddOn—Wowza StreamLock AddOn provides near-instant provisioning of free 256-bit SSL certificates and greatly simplifies deploying the proven security of SSL to wrap your RTMP session using RTMPS. StreamLock-provisioned certificates provide the best security when used with RTMP, but they can also be used for secure HTTP streaming (HTTPS).
are the extra steps to secure HTTPS or enabling this add-on will do automatically?
AES-128 requires an extra HTTP(S) call to get the decryption key, so it may be a bit slower (though HTTPS handshake could be as slow as making an extra call).
But are there any considerations which favor either one of these 2 methods from security perspective? Which one is more secure?
