       }   
}   
 
<input type="hidden" name="passWord" value=<%=session.getAttribute("GSAM_PASSWORD")%>></input>   
 <input type="submit" name="submit" value="Show Map" class="button" onclick = "validate_form();"/>  
function getUrl(gsamName,deviceName,userName,passWord){
window.open("./viewMapToolScreen.html?com.smarts.autoAttachDM="+gsamName+"&class=com.smarts.webapps.SmWebMapApp&com.smarts.launch.class=UnitaryComputerSystem&com.smarts.launch.instance="+deviceName+"&com.smarts.map.showAllBusiness=1&com.smarts.userid="+userName+"&com.smarts.password="+passWord);
}
 
 
function validate_form()
{
        valid = true;
        if ( document.map_form.contract.selectedIndex == 0 )
        {

                valid = false;
        }
 
                getUrl(document.map_form.gsamName.value,document.map_form.devicename.value,document.map_form.userName.value,document.map_form.passWord.value);

you can only obfuscate it. but anything generated/processed on the client side can be viewed by the user (though it may require more or less effort).

Hi Dormilich,

Good to see your reply.
is there any chance for me to encode password like ****.
waiting for your suggestion.

you can "encode" your password like that in the HTML display, but the application receiving the password won’t be able to decode it from the URL string.

besides that, experienced hackers can go linewise through your JavaScript code and visualize any occuring variable content (including the raw password before "encoding") (depending on the intention of the user this is called either cracking or debugging)

Here's the usual procedure.

1) Establish a secure connection using public key cryptography.

2) Encrypt the password or password hash using the public key.

3) Once authenticated, switch to private key cryptography for speedier transactions.

There's no need to reinvent the wheel. Use HTTPS, it's what it was made for.
