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. WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used.
