cryptlib

A module to encrypt/decrypt string in Node, written in ES6 (src folder) and transpiled using Babel to ES5(dist folder).

Using companion framework libraries, you should be able to encrypt/decrypt between node, iOS, Android and Windows platforms.

Companion libs can be found here: Cross Platform AES Encryption

Installation

npm install cryptlib --save

Usage

Encrypt

var cryptLib = require('cryptlib'),
    iv = cryptLib.generateRandomIV(16), //16 bytes = 128 bit
    key = cryptLib.getHashSha256('my secret key', 32), //32 bytes = 256 bits
    encryptedText = cryptLib.encrypt('This is the text to be encrypted', key, iv);

Decrypt

var cryptLib = require('cryptlib'),
    iv = 'iv vector used for encryption',
    key = cryptLib.getHashSha256('my secret key', 32), //32 bytes = 256 bits
    originalText = cryptLib.decrypt('M2rfrn9DqNHJe3Hev9nMxKKgIHoqUsc7FJM+tBGxIrl3Wk9UeKIQ5fRUUZF3q2i5', key, iv);
