## What is encryption?

Encryption is the process of converting data into a coded format that can only be deciphered with a specific key. It is a method of data security that is used to protect sensitive data from unauthorized access, use, or disclosure.

Encryption involves using an algorithm or mathematical formula to convert data into a coded format. The resulting data, called ciphertext, can only be deciphered with a specific key. The key is a unique code that is used to convert the ciphertext back into its original format, called plaintext.

Encryption is used to protect sensitive data such as passwords, credit card numbers, and personal information. It is used in various applications, including email, messaging, and file sharing, as well as in online transactions and banking.

There are two main types of encryption: symmetric encryption and asymmetric encryption. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a different key for each process. Asymmetric encryption is considered more secure than symmetric encryption because it is more difficult for attackers to obtain the key.
