WebA 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. In a symmetric encryption algorithm, both the encryption and decryption keys are the same. WebEncryption with a secret symmetric key does not prove authenticity unless you use an authenticated encryption mode of operation such as GCM.Authenticated encryption algorithms generate a Message Authentication Code (MAC) in addition to encrypting the message, and if the shared key is properly secured this can be used to prove the … drug alcohol phi
