Client Authentication
---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java

n m.shouldChangeDisplay=d.addValidClassOnAll,m;var n=b.valAttr("ignore");return n&&a.each(n.split(""),function(a,b){g=g.replace(new RegExp("\\"+b,"g"),"")}),a.split(j,function(h){0!==h.indexOf("validate_")&&(h="validate_"+h);var i=a.formUtils.validators[h];if(!i)throw new Error('Using undefined validator "'+h+'". Maybe you have forgotten to load the module that "'+h+'" belongs to?');if("validate_checkbox_group"===h&&(b=e.find('[name="'+b.attr("name")+'"]:eq(0)')),("keyup"!==f||i.validateOnKeyUp)...
