  30         Simple and very unsafe example login page for CGIscriptor.pl. The password is first hashed with the
  31         site specific salt (as it is used to store the password on-site). Then it is hashed with a random,
  32         one-time salt. Effectively, creating a one-time password. Only the last value is send to the server.
  33         The server has both salt values stored. It will ignore anything except the username, hashed password, and
  34         loginticket.
  35 </p>
  36 <p>
  37         The Session Ticket information is stored in <a href="http://www.xul.fr/en/html5/sessionstorage.php">
  38         <em>sessionStorage</em></a> with key <em>CGIscriptorPRIVATE</em>. Older browsers might not implement
  39         <a href="http://www.xul.fr/en/html5/sessionstorage.php"><em>sessionStorage</em></a>, or it might be
  40         turned off in the <a href="http://kb.mozillazine.org/Dom.storage.enabled"><em>dom.storage.enabled</em></a>
  41         parameter.
  42 </p>
  43 <form method="POST" action="" id="LoginForm"
  44         onSubmit='var success=check_username_password();SetSessionCookie();HashPassword("<SCRIPT TYPE="text/ssperl">
  45         $RANDOMSALT</SCRIPT>");success'>
  46 <div style="margin-left: 30%; margin-right: 30%; text-align: right">
  47   <table>
  48   <tr><td>Username:</td><td><input type="text" name="USERNAME" id="USERNAME" size="20" /></td></tr>
  49   <tr><td>Password:</td><td><input type="PASSWORD" name="PASSWORD" id="PASSWORD" size="20" /></td></tr>
  50   <tr><td></td><td style="text-align: left"><input type="submit" value="Login" /></td></tr>

  53   <input type="hidden" name="LOGINTICKET" value="<SCRIPT TYPE="text/ssperl">$LOGINTICKET</SCRIPT>" />
  54 </div>
  55 </form>
  56 <p>
  57         There are three default test accounts, all three have password <em>test</em>:
  58         <ul>
  59         <li>test: A SESSION ticket account</li>
  60         <li>testip: An IPADDRESS ticket account</li>
  61         <li>testchallenge: A CHALLENGE ticket account</li>
  62         </ul>
  63 </p>
  64
  65 <p>
  66 The Salt and Ticket values are all created using SHA256 on 64 Byte of output from <em>/dev/urandom</em> in HEX.
