WebAug 9, 2024 · 1 The accepted answer uses AES in CBC mode (the default Mode of RijndaelManaged) but it does not perform message authentication code (MAC) verification which is necessary while using AES in CBC mode. MAC prevents an adversary from altering the IV or ciphertext without getting detected. WebAug 12, 2024 · Aes aes = Aes.Create (); The execution of the preceding code generates a new key and IV and sets them as values for the Key and IV properties, respectively. Sometimes you might need to generate multiple keys. In this situation, you can create a new instance of a class that implements a symmetric algorithm.
