test.php

<script LANGUAGE="Javascript" SRC="js/md5.js"></script>  <script>   function encryptPwd1(strPwd, strSalt, strit)  {   var strNewSalt = new String(strSalt);   if (strPwd == "" || strSalt == "")   {   return null;   }   var strEncPwd;   var strPwdHash = MD5(strPwd);   var strMerged = strNewSalt + strPwdHash;   var strMerged1 = MD5(strMerged);   return strMerged1;   }   function validateForm(strSalt, strit)  {   var strEncPwd = new String(encryptPwd1(document.getElementById("password").value, strSalt, strit));   document.getElementById("password").value = strEncPwd;   document.login.submit();   return true;   }  </script> <form method="post" action="test1.php">   <input type="hidden"   name="salt"   id="salt"    value="8qadr4xnCPW275BaNpYX">   <label class="login">Password:</label>   <input    name="password"   id="password"    type="password" />   <input type="submit"   name="gos"   id="gos"   value="Login"   onClick="return validateForm('8qadr4xnCPW275BaNpYX','38');">  </form>
