SSL Scanner royend 10-27-2007

I am doing some research for a school project on authentication at the
web and the risk for identity theft. How can unauthorized users misuse
your identity and get access to classified information.

For my research I have tried some programs which stops the TCP-package
with headers like HTTP/1.0 and infomation about data submitted by a
form e.g. password and username.

I have tried two web scanners:
1. Burpsuite
which I managed to intercept packeges for HTTP 1.0 and hence was able
to read inserted username and password in plaintext. Still it wasn't
able to stop SSL-traffic, although it should be able to when turning
the "Use SSL"-parameter on.
2. Nikto
which is supposed to be a great listener/scanner, but I have not been
able to make it work.

Is there any programs you would recommend which will handle SSL/TLS?
Would for instance a program like Ethereal be able to read packages
using SSL protocols?

Looking forward to your help.

you want to decipher encrypted connections into plaintext ?
if that's the case ... bugger off

Wow...
not the kind of reply I was hoping for.
And no, I don't need a deciphering tool. What I want is a tool which
may scan for packages sent via SSL/TLS, like Burpsuite does with
HTTP1.0. This tool lets me read the headers (also possible to alter
them before sending them to server, but for my purpose it is only
necessary to read). Also, the project focuses on the vulnerability of
the web, and I am hoping to shove that even though SSL is implemented
the packages might be vulnerable to a Man-In-The-Middle-Attack (please
correct me if I am wrong), as the packages might be intercepted by an
attacker.

Any advice is appreciated for a tool which might help me prove it.

If someone intercepts the packages using a man-in-the-middle-attack,
the encryption will break, thus alerting the user.

You cannot intercept encrypted packages
without alerting the user that someone _IS_ intercepting them.
Because the certificate will be wrong.

Part of the reason that SSL is encrypted is to stop
people doing what you propose.

So the quick answer is no you can't.
