By "sign with certificate", do you mean a signature box? Or do you mean a security certificate token verifed by a third party?
I have found this based n the touch event:
<canvas id="drawSurface" width="500px" height="500px" style="border:1px solid black;"></canvas>
<script type='text/javascript'>
window.addEventListener('load', function() {
var canvas = document.getElementById("drawSurface"),
context = canvas.getContext("2d");
if (window.navigator.pointerEnabled) {
canvas.addEventListener("pointermove", paint, false);
if(window.navigator.maxTouchPoints>1)
alert("Your user agent and hardware support multi-touch!");
}
else {
//Provide fallback for user agents that do not support Pointer Events
canvas.addEventListener("mousemove", paint, false);
}
function paint(event) {
if(event.buttons>0)
context.fillRect(event.clientX, event.clientY, 5, 5);
}
});
</script>
It is a cut and paste from here:
http://www.w3.org/TR/pointerevents/
As In HTML5 there is a standard for touchevents.
All the script does is trap a touch event, and "draws" a blip at the clients x and y coords as long as the screen is being touched with the "canvas" element.
I hope this helps.

So is is a third party certificate or what?
I see that you asked this question again.
Didn't I give you good enough direction. It is either a touch event on a canvas in HTML 5 or a third party security certificate that YOU MUST PURCHASE FROM A THIRD PARTY.
Let me know if I am missing another certificate it could be! :)

That is then provided by the third party. You must pay for that service.

Didn't find the answer you are looking for?

OK, so what is the question. YOu already know what you want. Go to your SSL vendor for support. That is what you are paying for.
