You can rate examples to help us improve the quality of examples. WebWith AES, we can have a block cipher mode, a stream cipher mode, and AEAD (Authenicated Encryption With Additional Data). In this case we will implement GCM (AEAD), CFB (Stream) and CBC (Block), and will use PBKDF2 to generate an encryption key of a given size (128-bit, 192-bit and 256-bit).
