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. WebIt is essential that keys in symmetric-key algorithms are random bytes, instead of passwords or other predictable data. The random bytes should be generated using a …
