Caesar cipher (or Caesar program code) can be a shift cipher, one of the nearly all easy and most famous encryption techniques.It utilizes the substitution of a notice by another oné further in thé alphabet.
Caesar program code is described on an alphabet change: a letter more in the alphabet. Simple Alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ Caésar Alphabet (3) DEFGHIJKLMNOPQRSTUVWXYZABC Illustration: Crypt DCODEX with a change of 3. To encrypt N, consider the alphabet and look 3 letters after: G. To encrypt X, loop the alphabet: after X: Con, after Y: Z ., after Z: A. So A is usually coded A. DCODEX can be coded GFRGHA Another method to crypt, even more mathematical, take note A0, N1,., Z .25, and add a constant (the shift), then the result modulo 26 (alphabet length) is the coded text. Illustration: To crypt Deb (of value 3 ), add the change 3: 336 and discover the letter for 6: 6G, therefore D is usually crypted with G. To encrypt Back button23, 23326 and 26 mod 26 0, 0A, so X can be encrypted with A, etc. To decrypt Gary the gadget guy, consider the alphabet and look 3 letters before: M. To decrypt Back button, cycle the alphabet: before A new: Z ., before Z: Y, before Y: X. Example: Take Gary the gadget guy6, take away the change 6-33 and 3D, so G is usually decrypted with D Take A0, 0-3-3 and -3 mod 26 23, 23X, therefore A is definitely decrypted with Back button, etc. Also, the presence of key words and phrases Iike Brutus, Augustus, or á(Caesar) greens can remind us of the Caesar imperator. Another version changes the alphabet, and expose digits for example. A Caesar cipher with an offset of In corresponds to an Affine cipher AxB with A1 and BN. Illustration: 9 gets to be 12 (change of 3) - Integrate amounts in the alphabet. Illustration: With the aIphabet ABCDEF123, 21 becomes BA with an balance of 3.
