Cryptography key generation methods
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. WebSteps to create a One-time Password Generator in Java.
