The goal of sslcaudit project is to develop a utility to automate testing SSL/TLS clients for resistance against MITM attacks. It might be useful for testing a thick client, a mobile application, an appliance, pretty much anything communicating over SSL/TLS over TCP.
SSLsplit is a tool for man-in-the-middle attacks against SSL/TLS encrypted network connections. Connections are transparently intercepted through a network address translation engine and redirected to SSLsplit. SSLsplit terminates SSL/TLS and initiates a new SSL/TLS connection to the original destination address, while logging all data transmitted.
sslstrip is a tool that transparently hijacks HTTP traffic on a network, watch for HTTPS links and redirects, and then map those links into look-alike HTTP links or homograph-similar HTTPS links. It also supports modes for supplying a favicon which looks like a lock icon, selective logging, and session denial.
