...video and audio. How the connection works now is We create a room with a roomID and the peers make a request to the server with the roomID in the url. RoomID will be put in the same room and they start streaming video and audio. But it's too insecure and I need to generate a diffie hellman key pair on each peer (both desktop and mobile) and exchange the public keys. But I could not figure out how DH key exchange works. And where the keys are stored in mobile and how I can access them from the mobile phone so that I can encrypt the audio with the phones public key and then on the phone i can decrypt it using the key. （需要做的是为我在webrtc服务器上直播视频和音频的现有项目增加DH密钥交换算法的功能。 我原来的项目代码是录音web端和手机端的音频，并将它们进行比较延迟，作为两个端是否是在同一环境的双因素身份验证。我要改进的是使用webrtc直播音频来比较它们，把录音这一步替换掉。 我已经做好了的是部署webrtc信...
