trenker/simple-rsa

Easy to use and integrate API for using RSA encrypted values during HTTP communication.

RSA Framework for Browser-Server

A simple framework for RSA encryption of form field values in browser - server communication using Javascript and PHP., _(*1)

Useage

Requirements

You will need a server with PHP 5.3 installed and a web browser that does not choke on more complicated javascript code., _(*2)

Installation

Install via composer, _(*3)

composer install trenker/simple-rsa

Now you can create a key pair like this:, _(*4)

require 'vendor/autoload.php';

$key = \RSA\KeyPair::createNew();

On the client side, include the rsa.js file (or the rsa.min.js file if you want to keep it small)., _(*5)

You can autoload the rsa scripts using the JavascriptHelper::getFrontendUrl function, _(*6)

This will publish the the minified script to an accessible location. By default it is DOCUMENT_ROOT/scripts/rsa.min.MTIME_TIMESTAMP.js. This can easily be adjusted using the arguments or the function. Please take a look into the source file for details, _(*7)

After the script tag, that loads the rsa.js file you can use $key->toJavascript(); function to create a code snippet that takes care of setting the values and creating an instance. eg:, _(*8)

For a full example see the demo/index.php file, _(*9)
