Simple password protection using a md5 hashed slug in Siteleaf (note: this is not intended for high security, only to stop casual visitors)

index.html

<form>

  <input id="password" type="password"/>
  <button>Submit</button>
  
</form>

password.js

// uses https://code.google.com/p/crypto-js/

$("form").submit(function(e) {
  
  // recreate hashed slug
  var hashed_slug = CryptoJS.MD5($('#password').val());

  // attempt to load in contents
  $("body").load("/clients/"+hashed_slug, function(response, status, xhr) {
    // if password was entered incorrectly this will be a 404
    if (status == "error") alert("Incorrect password"); 
  });
  
  e.preventDefault();
  
});

You correctly guesed the password: "secret"

Use a tool like this to generate md5 hashes: http://www.miraclesalad.com/webtools/md5.php

e.g. secret becomes 5ebe2294ecd0e0f08eab7690d2a6ee69
