WebThere are two main approaches for how existing data that was encrypted with the old key (s) should be handled: Decrypting it and re-encrypting it with the new key. Marking each item with the ID of the key that was used to encrypt it, and storing multiple keys to allow the old data to be decrypted. Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message). Encryption attempted to ensure secrecy cieh9-242 ss
