![]() ![]() NET Framework 4.7 or later versions on your apps, and target. Directly using WCF clients and services using the System.ServiceModel namespace.Directly using the System.Net APIs (for example, and ).This document targets developers who are: NET Framework applications remain secure, the TLS version should not be hardcoded.NET Framework applications should use the TLS version the operating system (OS) supports. NET Framework applications that use the TLS protocol. This article presents recommendations to secure. TLS 1.2 will eventually be replaced by the newest released standard TLS 1.3 which is faster and has improved security. TLS 1.2 is a standard that provides security improvements over previous versions. For example, you are using Linphone with DTLS as FreeSWITCH clients or in case you need to originate a WebRTC call, but you are not calling a SIP UA that is registered with FS (if the UA is registered with FS, FS knows it should originate a WebRTC call).The Transport Layer Security (TLS) protocol is an industry standard designed to help protect the privacy of information communicated over the Internet. To send an INVITE to a WebRTC client or if you just need to send a call using DTLS encryption. This is why a proper certificate is essential even when testing WebRTC. Chrome will not even tell you why when it refuses them. WebRTC does not work properly with self–signed certs. Firefox has a strict policy if the websocket connection is initiated by a https page, it is mandatory the websocket connection is based on wss. It's more convenient to serve the page using https, because the browsers will be more acceptant in remembering the user gave permission to use the mic or the cam from the computer used when using standard http the browser will ask every time if it's ok. The starting point of a websocket connection is a web page, served by a webserver. Websockets can be used with (wss) and without (ws) encryption. The connection between the browser and Freeswitch when using WebRTC is based on websockets. Several Internet Explorer plugins are available. ![]() At the time of writing Chrome, Firefox and Opera support WebRTC natively. Internet browsers use PKI all the time, so WebRTC uses it too. Most of the times using WebRTC the client is a internet browser. Securing SIP SRTP ZRTP ZRTP IS NOW DEPREICATED and will be removed out of the docs WebRTC Let's Encrypt offers free short-term certificates good for testing a new FreeSWITCH™ instance with secure communications. Some protocols in Freeswitch use the PKI way of doing things, others just create a trust relationship using certificates on the fly to secure communication. There are plenty of 'certs for dummies' pages, please look there for the basics. Because it's been the standard in security on the internet since a lot of years it's also used for security in a lof of the protocols supported by Freeswitch. SSL (Secure Sockets Layer) and it's successor TLS (Transport Layer Security) are all about encrypting data flowing between two hosts. 5 ZRTP ZRTP IS NOW DEPREICATED and will be removed out of the docs.That's a thin line of course, but try to put in depth explanation of something like that in the home of that particular topic. The goal of the page is NOT to explain how the security of some module or protocol actually works. It also tries to explain some general things about the topic. This page tries to clarify as much as possible about this. It's not always obvious how to manage your certificate files, for instance where to put them, what the format should be and how to configure Freeswitch to use them properly. Certificate requirements are found in several areas of Freeswitch, and it's optional in a lot of other places. ![]()
