title: Trying to understand SSLKEYLOGFILE environment variable output format
body: <p>I have been messing around with the SSLKEYLOGFILE environment variable, and I am trying to understand what everything inside the output that it gives me (the .log file with all the session keys). 
  Here is a picture of what the output looks like:
  <a href="https://i.stack.imgur.com/1WZ5E.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1WZ5E.png" alt="enter image description here"></a></p>
  
  <p>I understand that these are keys, but what I notice is a space in the middle of each line, indicating to me that they are separate keys. What exactly are the 2 different keys that they are giving me, and how is WireShark able to use this file to decrypt ssl traffic?</p>
