I believe that is the best method. Though being a sysadmin myself I think
your safe from your sysadmin unless you pissed them off or they have a
reason to be monitoring you. preforming a wide spread MiTM attack on a
corporate network they are administrating is asking for trouble.

Ok so my question was posted in a forum and someone gave me and answer but
didnt explain it and then the forum post was when closed on me.  So I will
ask here for clarity and try not to kill me for this, I am trying to learn.

So if someone uses a corporate network to check a Gmail (using SSL).  If
they check to make sure that they have a secure connection -- once connected
-- and then they check the certificate to see if the cert hierarchy has been
tampered with.  Everything looks fine.  Are any admin or whomever able to
see you emails?  Forget about software on the computer you are using, only
through the network monitoring.

I was told in the forum that they could use a monitoring program like
wireshark to view them.  In the wireshark forum I read that you would need
the private key to decrypt the messages and in the forum they said that a
sys admin can get the private key?  Is that information correct?  and if so
how would they be able to get the private key?


Thanks in advance
