	Communications Proxy

Echo Mirage is a generic network proxy. It uses DLL injection and function
hooking to redirect network related function calls so that data transmitted
and received by local applications can be observed and modified.

Think of it as Odysseus (or Burp, if you prefer) that will proxy (almost)
anything...

Windows encryption and OpenSSL functions are also hooked so that the plain
text of data being sent and received over an encrypted session is also
available.

Echo Mirage tries to be smart with the OpenSSL calls by monitoring
ssl_set_fd() and ssl_connect() to determine when SSL is in use on a
particular socket.  When SSL is in use the encrypted stream is ignored and
only the unencrypted data is processed.  This doesn't work for the windows
SSL stuff because that functions in an entirely different way...

Traffic can be intercepted in real-time, or manipulated with regular
expressions and action scripts.

Theoretically, if I were to know your password, what would it be?
