# Caesar cipher

Calculator encrypts entered text by using Caesar cipher. Non-alphabetic symbols (digits, whitespaces, etc.) are not transformed.

**Caesar cipher** is one of the oldest known encryption methods. It is straightforward - it is just shifting an alphabet. Transformation is termed ROTN, where N is shift value, and ROT is from "ROTATE" because this is a cyclic shift.

For example, ROT2 means that "a" becomes "c," "b" becomes "d," and in the end, "y" becomes "a" and "z" becomes "b." The number of possible transformations is dependent on alphabet length, and for the English alphabet, it is 25 (ROT0 and ROT26 do not change the input text). Due to this, it is a very weak cipher because you can quickly check all possible combinations.

The calculator below outputs the table with all possible transformations. Non-alphabetic symbols like whitespaces and digits are not changed.
