Web14 Jan 2011 · Stream Ciphers crypts the plaintext data with a random stream of bit (usually with a XOR because it can be reversed easily). If you have a 128bit data, you will use a 128 bit pseudorandom stream (your key) to encrypt. Block Ciphers crypts the plain text data a block at a time with the same transformation (based on the key).

A keystream is a random 8-bit output that is generated by supplying a key to a pseudorandom bit … WebA stream cipher makes use of a much smaller and more convenient key such as 128 bits. Based on this key, it generates a pseudorandom keystream which can be combined with the plaintext digits in a similar fashion to the one-time pad. However, this comes at a cost. The keystream is now pseudorandom and so is not truly random.
