Socat is a commandline network tool akin to netcat. It supports SSL, IPv6 and several more protocols. It can come in handy when attempting to sniff traffic that has to speak SSL because setting up a cleartext to SSL proxy is relatively straightforward.
TCP to STDIN
To create a classic TCP listening daemon, similar to netcat -l, use a variation of the following command.
$ socat TCP-LISTEN:8080 stdout
Cleartext to SSL Tunnel for DyKnow
To create a plaintext to SSL proxy that DyKnow can connect to, use a variant of the following command.
$ socat tcp4-listen:1337,fork openssl:dyknow.lt.vt.edu:443,cafile=ThawtePremiumServerCA.pem
