Ask a new question Source codeĭCode retains ownership of the "Letter Number Code (A1Z26) A=1, B=2, C=3" source code. This cipher rotates (either towards left or right) the letters of the alphabet (A to Z). Use of modulo 26 in order to get 1=A,2=B,…26=Z then 27=A, 28=B etc. The Cipher Exchange (CE) is that department of The Cryptogram that deals with ciphers which are NOT simple substitutions of the Aristocrat/Patristocrat variety. Use of a custom alphabet, or reversed alphabet (A=26, Z=1) Monoalphabetic cipher is a substitution cipher in which for a given key, the cipher alphabet for each plain alphabet is fixed throughout the encryption process. ![]() Use of leading zeros to be able to concatenate numbers AB = 0102, else AB = 12 and 12 = L. But Caesar was not defeated so easily, and so the keyed Caesar cipher was developed. Use of a supplementary character for space (usually 0 or 27) A substitution cipher may be monoalphabetic or polyalphabetic: A single alphabet is used to encrypt the entire plaintext message. For each letter of your text, move it along the alphabet by a number of places. Shift of numbers: the alphabet can start with A = 0 or A = 1, but also A = 65 or A = 97 ( ASCII code). This will be our key that will allow us to encrypt and decrypt the message. ![]()
