Introduction
Encryption is the process of encoding messages or information so that only authorized parties can see it. Encryption has been going on for centuries. For example, in World War II Allied forces were sending out encrypted codes using the unwritten Navajo language, which was impossible for the Japanese to decode.
Today encryption is even more important because we live in an era where privacy and security are constantly under attack from hackers who want access into our personal lives. Thanks to modern technology like AES encryption, there's no reason why hackers should read sensitive information.
