TLS Secure Connections

Introduction

TLS is a protocol that provides privacy and data integrity between two communicating applications.
TLS is the successor to the Secure Sockets Layer (SSL).

Prerequisite

Basic understanding of how the internet works

Use Case

TLS is used in applications such as web browsing, email, instant messaging, and voice over IP (VoIP).
TLS is also used in many other applications and protocols.
A good example is the use of TLS by applications that require users to log in to a website.

Cloud Research

I read about TLS and how it works and how it is used in the internet.
I also read about the TLS handshake and how it works.

Try yourself

I used the following commands to create a self signed certificate and key.

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365

I used the following command to create a server that uses the certificate and key.

openssl s_server -key key.pem -cert cert.pem -accept 44330 -www

You can refer to the following link for more information on the openssl s_server command.

☁️ Cloud Outcome

I learned about TLS and how it works and how it is used in the internet.
I was able to do some hands on with TLS and create a self signed certificate and key and also create a server that uses the certificate and key.
