Package Exports

simple-cipher-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (simple-cipher-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

simple-cipher-js

A simple cryptography library for NodeJS.

Installing:

Install with npm:

with yarn:

$ yarn add simple-cipher-js

or add it directly to your webpage using a CDN:

<head>
    <script src="https://cdn.jsdelivr.net/npm/simple-cipher-js@0.0.7/dist/index.min.js"></script>
</head>

if you are working off an older version of the CDN, simply replace simple-cipher-js@X.X.X with a more precise version #

Implementing:

const cipher = require('simple-cipher-js');

cipher.rot13.encrypt('hello world!'); // uryyb jbeyq!

import { rot13, caesar } from 'simple-cipher-js';

rot13.decrypt('fvzcyr pvcuref ner sha'); // simple ciphers are fun

caesar.encrypt('password', 23); // mxpptloa

Using the CDN:

    
<html> 
    <head>
        <script src="https://cdn.jsdelivr.net/npm/simple-cipher-js@0.0.7/dist/index.min.js"></script>
    </head>
</head>


// inside of js file (or script tag)
document.querySelector("body").onload = function() {
    var encrypt = cipher.rot13.encrypt('hello world');

    console.log('encrypt: ', encrypt);
}

API:

Rot13 Cipher

import { rot13 } from 'simple-cipher-js';
         

rot13.encrypt('special password') // => fcrpvny cnffjbeq
rot13.decrypt('fcrpvny cnffjbeq') // => special password

Caesar Cipher

import { caesar } from 'simple-cipher-js';
         

caesar.encrypt('et tu brute', 4) // => ix xy fvyxi
caesar.decrypt('ix xy fvyxi', -4) // => et tu brute
