the only information i found online is that RTMFP uses 128-bit cypher. Does anyone know what exact encryption technology is used?
according to OpenRTMFP, it uses AES, see https://github.com/OpenRTMFP/Cumulus/blob/master/CumulusLib/sources/RTMFP.cpp and https://github.com/OpenRTMFP/Cumulus/blob/master/CumulusLib/sources/AESEngine.cpp
