title: how to Authenticate login using Login, password and OpenSSL certificate?
body: <p>I have Php based Application. which works perfect with login and password. Now i want to implement authenticate using OpenSSL along with login and password. </p>
  
  <p>I have generated the OpenSSL in Linux server and i have to use the generated openSSL.cert file as certificated. I installed that in my browser and my DNS is set with https so it should promte for certificate,</p>
  
  <p>Now what i need is, When somebody tries to login wihtout certificate it should not now allow to login. I should check the certificated to authenticate the login. </p>
  
  <p>Is they any way to do this or am i being more ambitious ?
  if yes, How can i do this i php ? </p>
  
  <p>Thanks all.</p>
