#jQuery plugin to impliment RSA public key encryption

  Utilizes the pidCrypt libraries for client public key
  encryption while the associated PHP class uses
  OpenSSL to generate the necessary private/public key pairs used
  by this plug-in

  Fork me @

* jQuery libraries (required -
* pidCrypt RSA & AES libraries (required -
* jQuery cookie plugin (optional -
* OpenSSL < 0.9.8
* PHP < 5.3
* A modern browser (doh!)

* Multiple key support
* AES-256-CBC encryption of all keyring data
* Modal window dialog for selection of appropriate keyring entry when multiple keys exist
* HTML5 localStorage support
* HTML5 sessionStorage support
* Cookie support
* Debugging output

Here is an screenshot of an impelmentation bound to a form with multiple public keys forcing
a modal window pop-up along with debugging output at the bottom showing the encrypted public
keys stored within the HTML5 storage options.


* appID: Optional CSRF token
* storage: HTML5 localStorage, sessionStorage and cookies supported
* callback: Optional function used once server recieves encrypted data
* preCallback: Optional function to perform prior to form submission
* errCallback: Optional function to perform on errors

Here are a few usage examples to get you started

Default usage using HTML5 localStorage


Default Using HTML5 sessionStorage


Default using cookies (requires the jQuery cookie plug-in)


Example of using the callback method to process server response

$('#form').pidCrypt({callback:function(){ console.log(this); }});

Example of using the preCallback method to load a function prior to form

$('#form').pidCrypt({preCallback:function(){ console.log(this); }});

Example of using the errCallback method to load a function on error

$('#form').pidCrypt({preCallback:function(){ console.log(this); }});

Example of enabling a custom CSRF token (sets the X-Alt-Referer header value)

$('#form').pidCrypt({appID:'<?php echo $_SESSION['csrf-token']; ?>'});
