Encryption#
Encryption is the process of encoding information or data in such a way that it can only be accessed or read by someone with the appropriate decryption key. Encryption is used to protect the confidentiality and integrity of data, and to prevent unauthorized access to sensitive information. Encryption uses mathematical algorithms, known as encryption algorithms, to scramble data in a way that makes it unreadable to anyone who does not have the decryption key. There are many different types of encryption algorithms, and they can be classified based on the type of encryption they use (symmetric or asymmetric), the size of the encryption key, and other factors. Encryption is an important part of computer security, and is used in many applications, including online communication, data storage, and cloud computing.
