Asymmetric encryption.

Asymmetric encryption, or public-key encryption, is a type of cryptographic protocol that uses a public and private key to exchange encrypted data between two users or devices. The development of asymmetric encryption in the 1970s was essential to encrypting communications over the internet and remains a popular method for securing data .

Asymmetric cryptography is a branch of cryptography where a secret key can be divided into two parts, a public key and a private key. The public key can be given to anyone, trusted or not, while the private key must be kept secret (just like the key in symmetric cryptography). Asymmetric cryptography has two primary use cases: authentication ...1975: Diffie imagines asymmetric cryptography. Whitfield Diffie and Martie E. Hellman write a paper called New directions in cryptography, in which they describe the idea of asymmetric cryptography. 1976: Diffie-Hellman key exchange. This operation allows two principals to set up a shared key given a public-key system.Cryptography vs encryption: Cryptography is the science of concealing messages with a secret code. Encryption is the way to encrypt and decrypt data. The first is about studying methods to keep a message secret between two parties (like symmetric and asymmetric keys), and the second is about the process itself.

Asymmetric encryption is designed to protect data and key exchanges over open, insecure channels. The aim of asymmetric key encryption is to provide a method for securely encrypting data across public channels, in addition to authentication and data integrity. The sending computer encrypts the secret data using the receiving computer's public key and a mathematical operation. The power of public key encryption is in that mathematical operation. It's a "one-way function", which means it's incredibly difficult for a computer to reverse the operation and discover the original data.Asymmetric cryptography uses multiple keys—some shared and some private.
