Help decrypt Caesar shift cipher-encrypted strings with an unknown shift value.
npm install @shreyravi/decrypt-caesarA package to help decrypt Caesar shift cipher-encrypted strings with an unknown shift value.
$ npm install @shreyravi/decrypt-caesar
Usage
const decryptCaesar = require("@shreyravi/decrypt-caesar");decryptCaesar("Fdhvdu Flskhu Xqhqfubswhg");
Unencrypted: "Caesar Cipher Unencrypted" with shift of 3,Thus, the _third_ element of resulting array is the correct decrypted result.
decryptCaesar("Fdhvdu Flskhu Xqhqfubswhg") => [

Index of result in array is equal to shift of Caesar cipher.If shift is known, then just index result with shift value:
const shift = 3; // known shift
decryptCaesar("Fdhvdu Flskhu Xqhqfubswhg")[shift] => "Caesar Cipher Unencrypted"
