WebAug 14, 2024 · The Caesar Cipher encryption rule can be expressed mathematically as: c = (x + n) % 26. Where c is the encoded character, x is the actual character, and n is the number of positions we want to shift the character x by. We’re taking mod with 26 because there are 26 letters in the English alphabet. 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.

A block cipher operates on complete blocks of data at any one time and produces a ciphertext block of equal size. DES is a block cipher that operates on data blocks of 64 bits in size. DES uses a 64-bit key 8 × 8 including 1 bit for parity, so the actual key is 56 bits.
