/*
* ssltap.c
*
* Version 1.0 : Frederick Roeber : 11 June 1997
* Version 2.0 : Steve Parkinson : 13 November 1997
* Version 3.0 : Nelson Bolyard : 22 July 1998
* Version 3.1 : Nelson Bolyard : 24 May 1999
*
* changes in version 2.0:
* Uses NSPR20
* Shows structure of SSL negotiation, if enabled.
*
* This "proxies" a socket connection (like a socks tunnel), but displays the
* data is it flies by.
*
* In the code, the 'client' socket is the one on the client side of the
* proxy, and the server socket is on the server side.
*
