Rotten Encryption

Node package to encode/decode text using a Caesar Shift (or ROT-n) cipher.

Background

I recently discovered a renewed interest in basic encryption. In an effort to continue my node.js education, I decided to write a simple package to encrypt/decrypt strings using a ROT-n cipher (also commonly known as a Caesar Shift).

Note: This is an incredibly rudimentary cipher. Please do not use this package for any serious encryption needs.

Installation

npm install rotten-encryption

Usage

var rotten = require('rotten-encryption');

// number of steps to shift the resulting alphabet
var shift = 6;

// encrypt an input string
rotten.encrypt(shift, 'string to encrypt');

// decrypt an input string
rotten.decrypt(shift, 'string to decrypt');
