Summary</H3>
|
|
A command-line proxy which is SSL-aware. It snoops on TCP connections,
|
|
and displays the data going by, including SSL records and handshaking
|
|
if the connection is SSL.

Description</H3>
|
|
SSLTap opens a socket on a rendezvous port, and waits for an incoming connection
|
|
(client side). Once this connection arrives, SSLTap makes another connection
|
|
to hostname:port (server side). It passes any data sent by the client to
|
|
the server, and vice versa. However, SSLTap will also display the data
|
|
to the console. It can do this for plain HTTP connections, or any TCP protocol.
|
|
However, SSLTap can also work with SSL streams, as detailed below.
|
|
|
|
<P>Let's assume your development machine is called 'intercept'. The simplest
|
|
usage of SSLTap is to run the command <TT>'ssltap www.netscape.com:80'</TT>
|
|
on intercept. The program will wait for an incoming connection on port
|
|
1924. Next you would want to go to your browser, and enter the URL http://intercept:1924.
|
|
The page retrieved by the browser will actually be gotten from the server
|
|
at www.netscape.com, but will go via SSLTap.
|
|
|
|
<P>Data sent from the client to the server is surrounded by a '--> [ ]'
|
|
symbol, and data sent from the server to the client, a '<---[
|
|
]' symbol.
|
|
|
|
<P>You'll notice that the page retrieved with this example looks incomplete.
|
|
This is because SSLTap by default closes down after the first connection
|
|
is complete, so the browser is not able to load images. To make the SSLTap
|
|
continue to accept connections, switch on looping mode with the -l option.
|
|
|
|
<P>You can change the default rendezvous port to something else with the
|
|
-p option.
|
|
|
|
<P>The remaining options change the way the output is produced.
|
|
|
|
<P>The -f option prints 'fancy' output - in colored HTML. Data sent from
|
|
the client to the server is in blue. The server's reply is in red. This
|
|
is designed so you can load the output up into a browser. When used with
|
|
looping mode, the different connections are separated with horizontal lines.
|
|
|
|
<P>-x will turn on HEX printing. Instead of being output as ascii, the
|
|
data is shown as Hex, like this:

<H4>
|
|
SSL Parse mode</H4>
|
|
The following options deal with SSL connections.
|
|
<UL>-s will turn on SSL parsing. (SSLTap doesn't automatically detect SSL
|
|
sessions.)
|
|
<BR>-x will turn on extra SSL hexdumps. Mostly, if SSL can decode the data,
|
|
it doesn't display the hex.</UL>
|
|
The following SSL3 Data structures are parsed: Handshake, ClientHello,
|
|
ServerHello, CertificateChain, Certificate. In addition, SSL2 ClientHello,
|
|
ServerHello, ClientMasterKey are also partly parsed. NO DECRYPTION IS PERFORMED
|
|
ON THE DATA. SSLTAP CANNOT DECRYPT the data.
|
|
|
|
<P>If a certificate chain is detected, DER-encoded certificates will be
|
|
saved into files in the current directory called 'cert.0x' where x is the
|
|
sequence number of the certificate.
|
|
<BR>
|
|
<H3>
|
|
Operation Hints</H3>
|
|
Often, you'll find that the server certificate does not get transferred,
|
|
or other parts of the handshake do not happen. This is because the browser
|
|
is taking advantage of session-id-reuse (using the handshake results from
|
|
a previous session). If you restart the browser, it'll clear the session
|
|
id cache.
|
|
|
|
<P>If you run the ssltap on a different machine that the ssl server you're
|
|
trying to connect to, the browser will complain that the host name you're
|
|
trying to connect to is different to the certificate, but it will still
|
|
let you connect, after showing you a dialog.
