SSLDUMP 0.9b3
|
|
|
|
ssldump is an SSLv3/TLS network protocol analyzer. It identifies TCP
|
|
connections on the chosen network interface and attempts to interpret
|
|
them as SSLv3/TLS traffic. When it identifies SSLv3/TLS traffic, it
|
|
decodes the records and displays them in a textual form to stdout. If
|
|
provided with the appropriate keying material, it will also decrypt
|
|
the connections and display the application data traffic.
|
|
|
|
ssldump depends on the libpcap packet capture library. Some systems
|
|
(e.g. FreeBSD) now have libpcap as part of their standard install. On
|
|
other systems, you will need to install it. You can obtain the
|
|
distribution from:
|
|
http://www.tcpdump.org/
|
|
|
|
If linked with OpenSSL, ssldump can display certificates in decoded
|
|
form and decrypt traffic (provided that it has the appropriate keying
|
|
material). Again, OpenSSL may be installed on your system. Otherwise
|
|
you can obtain it from:
|
|
http://www.openssl.org/
|
|
|
|
See the file INSTALL for instructions on building and installing
|
|
ssldump.

|
STABILITY
|
|
This is a beta release of ssldump. The UNIX portions have received
|
|
extensive testing and are believed to be quite solid. The Windows
|
|
port is substantially less stable.

|
INTEROPERABILITY NOTE
|
|
Previous versions of ssldump automatically looked for the keyfile
|
|
in 'server.pem' and used the password 'password'. This version
|
|
removes those defaults. For decryption to work you MUST specify
|
|
the keyfile (and password if the keyfile is encrypted.)

_SSL_and_TLS_ makes extensive use of ssldump to demonstrate real-life
|
|
SSL behavior. If you like ssldump and want to learn about SSL, you
|
|
might consider buying my book.
