How to install JS extension

Hello Community

I am trying to set up a password verification in Java Script and I need to use a external library for the hashing. How can I define the CryptoJS.md5 function that is used in the code below?

//====================================================================
//functon for loading of javascript and css
//====================================================================
$scope.loadjscssfile= function(filename, filetype){
 console.log("loading "+filename+":: type="+filetype)
 if (filetype=="js"){ //if filename is a external JavaScript file
 var fileref=document.createElement('script')
 fileref.setAttribute("type","text/javascript")
 fileref.setAttribute("src", filename)
 }
 else if (filetype=="css"){ //if filename is an external CSS file
 var fileref=document.createElement("link")
 fileref.setAttribute("rel", "stylesheet")
 fileref.setAttribute("type", "text/css")
 fileref.setAttribute("href", filename)
 }
 if (typeof fileref!="undefined")
 document.getElementsByTagName("head")[0].appendChild(fileref)
}

//====================================================================
// Enter the View
//====================================================================
$scope.$on('$ionicView.afterEnter', function() {
 
 /*$scope.loadjscssfile("app/resources/Uploaded/picker/lib/simplepicker.css", "css")*/
 $scope.loadjscssfile("app/resources/Uploaded/md5.js", "js");
 
})
function generatePasswordHash(password) {
 var hash = CryptoJS.MD5(password).toString();
 console.log(hash);
 // Use the generated hash as needed
}

var password = 'myPassword123';
generatePasswordHash(password);

Thanks for your help.

Best whishes
