Cryptography is the art of creating codes to encrypt information – meaning to jumble it and make it unreadable – and keep it secret. It’s all about encoding data, so that only the people who were meant to see it will see it. It’s very old, and exists in many different forms, but it’s purpose is always to hide information. Modern cryptography uses sophisticated mathematical equations (algorithms) and secret keys to encrypt and decrypt data.
