TLS 1.2, TLS 1.3, Cipher Suites and Session resumption

I was under the misconception that the Web Server will encrypt the data using its Private Key and the browser will decrypt using the corresponding Public Key available in X.509 certificate. I never knew the Session Key will be derived individually at the Client and Server using the Pre-shared Secret and other parameters. Only after watching the Troubleshooting with Wireshark: Analyzing and Decrypting TLS Traffic in Wireshark (Using HTTPs) Pluralsight course, I got the HTTPS enlightenment. The below articles provide more info about TLS 1.2, TLS 1.3, Cipher Suites and Session resumption:

Corona Virus Status in Tamil Nadu

As I was searching for the daily Corona Virus status report in Tamil Nadu, I found a wonderful Web application COVID 19 India.

A group of dedicated volunteers are curating the news coming from state bulletins, press releases and news houses and have hosted a Web application, COVID 19 India. The data is very much organized and accurate.

Using the Cluster Map, we can get more information.

I will refer COVID 19 India and update the below Google Sheet.

Dr C Vijayabaskar, the Minister for Health and Family Welfare, Government of Tamil Nadu frequently gives updates in his Twitter handle.

The Our World in Data provides the complete statistics for India.
