Question

I need to send data via a url (it’s JSON’d) that I would like to encrypt using some method that I can then decrypt it using php. I was thinking base64, but I need a url safe base 64 (I’m using CI and CI removes +,= and /).

Is there anyway to duplicate

function url_base64_encode(&$str="")
{
    return strtr(
            base64_encode($str),
            array(
                '+' => '.',
                '=' => '-',
                '/' => '~'
            )
        );
}

in Javascript?

Or some other alternative?
