WebThe Caesar cipher (or Caesar code) is a monoalphabetic substitution cipher, where each letter is replaced by another letter located a little further in the alphabet (therefore shifted but always the same for given cipher message). The shift distance is chosen by a number called the offset, which can be right (A to B) or left (B to A). Web2. To encrypt a series of plaintext blocks p 1;p 2;:::p n using a block cipher E operating in cipher block chaining (CBC) mode, each ciphertext block c 1;c 2;:::c n is computed as c i= E k(p i c i 1), where c 0 is a public initializa- tion vector (IV) which should be di erent for each encryption session.

It does not need a physical machine to realise it. Instead of true randomness, it takes input a password, key, or seed, and expands that to a long string of bits, which are derived ...
