title: How to add JKS file to HttpClient request
body: <p>I'm trying to send http requests with a cert, 
  when in using the SoapUi I'm adding a JKS file to the request and it works great, and now I'm trying to implement this in .Net Core code. 
  I'm using <code>HttpClient</code> for the request and I don't know how can I attach the JKS file. </p>
  
  <p>Any Ideas? </p>
  
  <p>Thanks </p>
