title: php post password routines?
body: <p>I am very interested to find out how to keep php passwords secure.</p>
  
  <p>Main question is: How do I post the password as a secured string from the login form?</p>
  
  <p>I have been checking how other sites do this e.g. facebook. When I log in to facebook I dont see my password posted at all, it just seems like a long encrypted string.</p>
  
  <p>How do I convert the password field to an encrypted string before posting? Is this done with ajax?</p>
  
  <p>Cheers
