Hi All, To put it simply, when you type in the password, it's in the browser client on your machine. When you press the submit button, this information is being sent to the secured destination as was defined in the log. For your browser to connect to the secured destination (before any data is submitted) it has to open SSL tunnel (hence handshake and key exchange...) between your computer and that destination. Only afterwards - the password will be sent.

Thereafter all data is encrypted. You don't send your password first. That would make no sense since the data is viewable as plain text.

So how are the credentials protected in network transit to the secure site? The way you explain it, I see the creds being exposed on their way to the secure site. Optimally they should enter their creds after ssl has setup the secure session, not after.. What am I missing?

Here is the situation: A website not using SSL has a login page. As soon as credentials are entered on this page they are redirected to a site using SSL. Here is a specific example of the code on one such site: <form name="loginpersonal" method="POST" action="https://secure.sitename.com/engine/login/login.asp" onSubmit="return checkLoginForm(this);"> <input type=hidden name=IsPostback value=1> Now, from what I understand, the login credentials would still be unencrypted while traveling to the secure site. So that would negate the effect of having it redirect to a secure site in the first place. Right? I keep brining up this fact but all I get back is that it's being redirected so it's secure. I feel like I'm taking crazy pills here so I'd appreciate some feedback. Am I wrong? If I am I can handle that, I'd just like to know. Thanks!
