encrypt/decrypt your binary buffers in JavaScript with RSA algorithm

CryptoRSA

encrypt/decrypt your binary buffers in JavaScript

How to Install

• Download:
  • Normal: Download the release and copy "CryptoRSA.js" in the folder of your project
  • Clone: insert the git bash command:

git clone https://github.com/mdjfs/CryptoRSA.git

• Install: Add references for JavaScript file in your html like this:

<script src="CryptoRSA.js"/>

Usage

Call a instance of CryptoRSA with this line of code:

var crypto = new CryptoRSA(private_key, public_key);

param private_key = Insert array with two numbers primes greater than 16 bits (your private key). For example: [38501, 45541] This key is needed to decrypt binaries

param public_key = Insert a number result of the multiplication of the two previous numbers (your public key). For example: 1753374041 (38501 * 45541) This key is needed to encrypt binaries

For example:

var crypto = new CryptoRSA([38501, 45541], 1753374041);

please, use your own numbers in your tests

You can also insert only public_key or private_key, examples:

var crypto = new CryptoRSA([38501, 45541]);

var crypto = new CryptoRSA(null, 1753374041);

How to encrypt? You can encrypt strings, numbers, files, etc.. But you need transform this in ArrayBuffer, after this, you can call a method CryptoRSA.encrypt to encrypt the ArrayBuffer, Example:

var result = crypto.encrypt(my_array_buffer);

This method returns a array of decimal numbers encoded

How to decrypt? You can call a method CryptoRSA.decrypt to decrypt the ArrayBuffer, Example:

var my_array_buffer = crypto.decrypt(result);

This method returns the original array buffer
