WebFeb 8, 2024 · It’s a public/private key asymmetric technique used mainly to transfer data over the internet. A browser sends a public key to a website’s server and requests some data. The server uses the user’s public key to encrypt the data and send it out. The user’s browser performs the cipher decryption with its private key. WebA symmetric encryption is any technique where the same key is used to both encrypt and decrypt the data. The Caesar Cipher is one of the simplest symmetric encryption techniques, and of course, one of the easiest to crack. Since then, cryptologists have invented many more symmetric encryption techniques, including the ones used today to …
