Rotation Cipher 🗝️
A lightweight utility for performing caesar ciphers. This classic cipher shifts characters in a given string by a specified amount to provide a small layer of encryption.
Capable of creating ciphers containing characters in the english alphabet (a-zA-Z) and human-readable ASCII characters.
Use cases:
- perform basic, custom, and randomized caesar ciphers
- generate a cool username / social media handle
Installation
Install the package from npm:
npm install rotation-cipher
Create ciphers on the fly:
import { caesarCipher } from 'rotation-cipher';
console.log(caesarCipher('tanner', 21));
// oviizm
Example usage
Basic Cipher
Rotate each character by the default 13 characters:
console.log(caesarCipher('tanner'));
// gnaare
User defined uniform rotation
Rotate each character by a uniform rotation:
console.log(caesarCipher('tanner', 17));
// kreevi
User defined uniform rotation (with ASCII)
Rotate each character by a uniform rotation including ASCII:
console.log(caesarCipher('t@nn3r!', 15));
// i,cc}g0
Custom rotation array
Rotate each character by a specific rotation:
console.log(caesarCipher('tanner', 0, [3, 5, 1, 2, 7, 8]));
// wfoplz
Random rotation
Rotate each character by a random rotation:
import { caesarCipher, randomRotation } from 'rotation-cipher';
let s = 'tanner';
console.log(caesarCipher(s, 0, randomRotation(s)));
