A SSLv3/TLS and SSLv2 proxy server that sniffs SSL/TLS packets and prints out the contents of packets in stdout. It can also serve as a (not very efficient) proxy server. Check out some sample output. Note that this tool does not decrypt or even attempt to decrypt the traffic that is routed through it.
