![]() ![]() Ask a new question Source codeĭCode retains ownership of the "Letter Number Code (A1Z26) A=1, B=2, C=3" source code. Use of modulo 26 in order to get 1=A,2=B,…26=Z then 27=A, 28=B etc. Use of a custom alphabet, or reversed alphabet (A=26, Z=1) Use of leading zeros to be able to concatenate numbers AB = 0102, else AB = 12 and 12 = L. Use of a supplementary character for space (usually 0 or 27) Instead, we will modify the shift value such that shifts = 26 - shift.Shift of numbers: the alphabet can start with A = 0 or A = 1, but also A = 65 or A = 97 ( ASCII code). The same function can be used for decryption. However, we can use the cyclic property of the cipher under the module. We can create a function that will accomplish shifting in the opposite path to decrypt the original text. The decryption is the same as encryption. The following mathematical formula can be used to shift n letter. We can represent this concept using modular arithmetic by first transmuting the letter into numbers, according to the schema, A = 0, B = 1, C = 2, D = 3……. This integer value is also known as the shift. There is an integer value required to define each latter of the text that has been moved down. It is a simple type of substitute cipher.Each text is replaced by the fixed number of position down or up with the alphabet. ![]() This technique is quite simple to apply encryption.This algorithm consists of a few features that are given below. There is an algorithm used to implement it. This method is named after popular frictional characters Julius Caesar, who used it to communicate with officials. For example - Alphabet B is replaced by two positions down D. In this technique, each character is substituted by a letter certain fixed number position it's later or before the alphabet. In this tutorial, we will explore one of the encryption methods called Caesar Cipher.
