This video explains how a communication between a client and a server is made secure using Secure Socket Layer (SSL). This video also delves into concepts of Symmetric and Asymmetric encryption and how SSL certificates are created.

What is SSL? SSL stands for Secure Sockets Layer, which is a protocol used to secure and encrypt communication over the internet. It ensures that data transmitted between a user's browser and a website's server remains private and secure. SSL encrypts the data, making it unreadable to anyone who might intercept it, thereby protecting sensitive information such as passwords, credit card numbers, and personal details.

What is Symmetric Encryption? Symmetric encryption is a method of encryption where the same key is used for both encryption and decryption of data. In symmetric encryption, the sender and the receiver use the same secret key to both encrypt and decrypt messages. This means that the sender encrypts the message with the key, and the receiver decrypts it using the same key.

What is Asymmetric Encryption? Asymmetric encryption, also known as public-key encryption, is a method of encryption where two different keys are used: one key for encryption and another key for decryption. These keys are mathematically related but distinct, and they are referred to as the public key and the private key.
