ssldump

An SSLv3/TLS network protocol analyzer
This program will dump the traffic on a network and analyze it for
SSLv3/TLS network traffic, typically used to secure TCP connections.
When it identifies this traffic, it decodes the results. When
provided with the appropriate keying material, it will also decrypt
the connections and display the application data traffic.
.
ssldump is based on tcpdump, a network monitoring and data acquisition
tool. More information on ssldump is available at
