In other words, the sender uses a secret key to encrypt the … WebSymmetry Symmetry Description Some block cipher modes, such as OFB, CTR, or CFB, turn a block cipher into a stream cipher. The idea behind stream ciphers is to produce a pseudorandom keystream which is then XORed with the plaintext. One advantage of stream ciphers is that they can work of plaintext of arbitrary length, with no padding required. how much peanut butter in a smoothie
