Replicate adyen client side encryption (html/js) in c#

Basically there is a website that does client side encryption of a form via adyen befor submitting the information. Basically I need a programm(script) that is able to replicate what is done with the client side encryption and return me the data that I would enter into the form encrypted just like the client side encryption does, but in my c# programm. I have the website source code, the javascript which does the client side encryption and there are also examples that illustrate how the adyen client side encryption works which should make it easier to understand.
