Do you want to make the password secure? If so javascript isn't the way to go. You would basically use javascript to check for validation and if you have the user verify the password you can use javascript to check that both inputs are the same.

It dosent need to be secure, i have 2 pages that have a password box, and i just want to make it so only one password works on the page and when they type it in it will go to another page.

So when you type the password in if it is correct you want it to go to another page?

**codeex** · Mar 23 '07, 05:14 PM

yes
and if its wrong to stay on the same page

People don't usually do this that is why we are asking so many questions. You do realize that the entire world can right click and view the source to see this password?

Here is an example:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html>
        <head>
            <title>Coming...</title>
                <script type="text/javascript">
		function CheckMe()
		{
		var strPassword = document.getElementById("strPassword").value
		if (strPassword == "New England Clam Chowder")
			{
				window.location="http://google.com"
			}
			else
			{
				alert("No Way Jose")
			}
		}
		



		</script>
        </head>
            <body>
		The Password Is: New England Clam Chowder
              	<form>
			<input type="password" id="strPassword" size="25" />
			<br />
			<input type="button" onclick="CheckMe()" size="25" value="Submit" />
		</form>
            </body>
</html>

you could do a md5 hash

Paj's Home: Cryptography: JavaScript MD5

http://pajhome.org.uk/crypt/md5/

I provide free JavaScript implementations of these secure hash algorithms. Their most common applications is for improving security on web login forms.

yes i do realize that its not import information im trying to guard its more of a block.

But how could i make it more secure??

Check out Clint's solution above I think it would be more than adequate for what you are trying to do.

No problem, let us know if you need anymore :)

I am not familer with hd5 hash code how would i do it??

**iam_clint** · Mar 23 '07, 05:54 PM

So you take your password

pass1 for example... use http://pajhome.org.uk/crypt/md5/ to convert it into md5 which will = a722c63db8ec862 5af6cf71cb8c2d9 39

you add this script to your page as an include if you want but add it to the page

then when the user inputs his password

you do
hex_md5("input string");

and compare with your md5 hash

Code:

<script>
function checkpass(val) {
if (hex_md5(val) == "a722c63db8ec8625af6cf71cb8c2d939") {
alert("correct password");
} else {
alert("wrong password");
}
}
</script>
 
 
<input type="password" id="pass">
<input type="button" onclick="var val = document.getElementById('pass'); checkpass(val);">

this would make it secure because

no one would know the password... viewing the source would only show them the md5 hash and good luck converting it back then you just convert what they input to md5 and compair the md5 hashes instead of strings.

so even if they know the hash if they put
a722c63db8ec862 5af6cf71cb8c2d9 39 into the password box it will then convert this into md5 and it would be different so i would say md5 is a pretty good security measure and lots of people use it (mostly server side).

if you don't understand post again on what part you don't understand.
