Private Key Encryption (Symmetric Key Encryption)

In private key encryption, data is encrypted using a single same key that only the sender and the receiver know. That is why private key encryption is also called symmetric key encryption because the same key is used during both encryption and decryption of the transmitted data.

In this video, I will also use an example to demonstrate the process of using private key encryption. Two different methods -stream encryption and block encryption- of private key algorithm are also depicted with animation.
