WebEncryption and decryption are inverse operations, meaning the same key can be used for both steps. Symmetric-key cryptography's most common form is a shared secret system, in which two parties have a shared piece of information, such as a password or passphrase, that they use as a key to encrypt and decrypt information to send to each other. Web1.2 The Pre-history of Encryption The task of encoding a message to preserve privacy is called encryption (the decoding of the message is called decrpytion), and methods for symmetric-key encryption have been studied for literally thousands of years.

Public-Key Encryption: What It Is & How it Works Arrow.com
WebThe two main kinds of encryption are symmetric encryption and asymmetric encryption. Asymmetric encryption is also known as public key encryption. In symmetric encryption, there is only one key, and all communicating parties use the same (secret) key for both encryption and decryption.
