Developing a real-time secure chat application like WhatsApp & Signal with end-to-end encryption.

Lately, there is a lot of fuss around end-to-End Encrypted chat applications. WhatsApp and Signal are two messaging apps dominating the headlines, let's take a look at why - 
WhatsApp recently updated its privacy policy, stating that the messaging platform will share user data with other Facebook-owned and third-party apps. This has prompted several users to look for alternative platforms, top among them is Signal. Signal is essentially an encrypted messaging app. Messages sent through Signal are said to be encrypted, meaning the platform cannot access private messages or media, or store them on their server. This is called end-to-end encryption. End-to-End Encryption(E2EE) is the most important feature in real-time chat applications.

Learn how to create a real-time chat application like WhatsApp & Signal including the implementation of Signal Protocol for End to end encryption! Here we use Web sockets in the NodeJS server for real-time connectivity and React for the Frontend development. The tutorial includes theoretical concepts, algorithms and comparative analysis of various social media applications followed by Code.

Have fun!

Hi, great video, thanks for uploading this,

If user clear their localStorage (clear Browser data), how to decrypt the old messages from DB?

[ingatrifan]

Nice explanation! Do someone know what store from encryptMessageAsync means? Where she got the store from? It is not clear.

I respect the efforts you put but It seems the whole lecture is about presenting some slides, this lady doesn't give a damn about what she speaks is making sense or not.
