Encryption is a way of securing data; it is done by encoding the data (plain text) into a cipher. This allows for the data to be sent publicly however only those with the correct encryption key will be able to read it.


There are 2 main types of encryption: Symmetric and Asymmetric.

In Symmetric encryption the same key is used to code and decode the data.

In Asymmetric encryption there are 2 keys, one public and one private. If you want to send data to someone you can use their public key to encrypt the data. then when they receive the ciphertext they use their private key to decode the data.

Encryption is the process of encoding data or a message so that it cannot be understood by anyone other than its intended recipient. Within data processing in a computer, encryption means that data can be stored and transmitted securely by the sending computer to the receiving computer. The data or message is encrypted using an encryption algorithm and decrypted on the other end by a decryption algorithm both which are kept secure.
