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 @



  • 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 submission

$('#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']; ?>'});
