MagicCrypt

Introduction

MagicCrypt is a Java/PHP/NodeJS library to encrypt/decrpyt strings, files, or data, using Data Encryption Standard(DES) or Advanced Encryption Standard(AES) algorithms. It supports CBC block cipher mode, PKCS5 padding and 64, 128, 192 or 256-bits key length. If the encrypted data is a string, it will be formatted automatically to Base64.

For Node.js

Installation

Run npm i or npm install to install.

npm install magiccrypt

If you want to save this module to package.json, please add --save option.

npm install magiccrypt --save

Initialization

Import this module by using require function.

const MagicCrypt = require('magiccrypt');

Then, input your DES/AES key and key length to create an instance of MagicCrypt.

var mc = new MagicCrypt(key, bit);

Also, you can set your initialization vector.

var mc = new MagicCrypt(key, bit, iv);

Encrypt

You can use encrypt method to encrypt any string. For example,

var mc = new MagicCrypt('magickey', 256);
console.log(mc.encrypt('http://magiclen.org'));

The result is,

DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ=

To encrypt any data buffer to a base64 string,

var mc = new MagicCrypt('magickey', 256);
console.log(mc.encryptData(buffer));

Decrypt

You can use decrypt method to decrypt any encrypted string. For example,

var mc = new MagicCrypt('magickey', 256);
console.log(mc.decrypt('DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ='));

The result is,

http://magiclen.org

To decrypt any base64 string to data buffer,

var mc = new MagicCrypt('magickey', 256);
var buffer = mc.decryptData(base64);
