Cryptology table
WebIt is convenient to use this table for shift codes. The rst line, the usual alphabet, is the plaintext line. Each line following represents a di erent shift a, for a = 1 to 25. For example, the line starting with D is the shift code with key letter D, corresponding to a =3. We can rework Example 1 easily using this table.

WebFixed tables are normally used, as in the Data Encryption Standard (DES), but in some ciphers the tables are generated dynamically from the key (e.g. the Blowfish and the Twofish encryption algorithms). Example [ edit] One good example of a fixed table is the S-box from DES (S 5 ), mapping 6-bit input into a 4-bit output:
