Hi Kashmira: Perhaps you are referring to this product or something similar? http://www.ieinspector.com/httpanalyzer/ What this product does, hooking into IE, is not normally called "sniffing" which is, I think, what the rest of us were responding to. If you only need to analyze HTTPS traffic from your own computer you would have several options in addition to the above tool ranging from simply using liveHttpHeaders for Firefox or IEWatch for IE to a proxy like Paros. If you need to intercept and decrypt SSL conversations on the network, you cannot do it without the server's private key and the ability to capture all the packets. And even then there are cases where it still cannot be done (ephemeral keying). If there were a way to intercept and decrypt SSL traffic without the server's private key, it would not be much of a "secure" socket layer and no one would be using it. -Garth --- "Phalak, Kashmira Vijay" <kphalak () verisign com> wrote:
Hi All, Thanks for your suggestions! But most of these products suggested need the private key to be supplied for decrypting the SSL traffic. The HTTP Analyzer which I initially tried, does not need the private key to be supplied and does a good job of decrytping SSL traffic. Can anyone explain to me how this works? But the HTTP analyzer only sniffs the traffic in the current user session. This behavior is different from that of ethereal when I set it in promiscuous mode. Here, I can see traffic from other machines on the same ether segment. I may be wrong here, but I don't see this in either ClearWatch,ssldump or ngrep. Thanks, Kashmira. -----Original Message----- From: Garth Somerville [mailto:therealgarth () yahoo com] Sent: Wednesday, July 20, 2005 6:43 AM To: webappsec () securityfocus com Cc: Phalak, Kashmira Vijay Subject: Re: Https sniffer Hi Kashmira: ClearWatch is a free tool from Covelight that will work great as an HTTPS sniffer. You will need to provide the server's private key to decrypt SSL traffic. You can find it here: http://www.covelight.com/downloads.php Cheers, -Garth Somerville __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
