The output is routed to a text file. Example 2 The -s option turns on SSL parsing. Because the -x option is not used in this example, undecoded values are output as raw data.
There is no SSL parsing or decoding. Both formats are shown for each record. Usage Tips When SSL restarts a previous session, it makes use of cached information to do a partial handshake. If ssltap binary system 2018 wish to capture a full SSL handshake, restart the browser to clear the session id cache.
