WebIt uses a fixed block size and the same key for both encryption and decryption. The key is expanded for each round of encryption to form an “Expanded Key”. In each round, a slice is taken from the Expanded Key and only used for this round. It’s sort of an advancement of repeated-key XOR. What’s different? To name a few: WebCryptopals Rule ¶ Always operate on raw bytes, never on encoded strings. Only use hex and base64 for pretty-printing. Base64 is a way of encoding any bytes into a printable string.
