WebThe most common keys are those used for data encryption; however, other types of keys exist for different purposes. A data encryption algorithm uses a (secret) key to convert a message into a ciphertext — that is, a scrambled, unreadable version of the message. One can recover the original message from the ciphertext by using a decryption key.
