Ken,
         It doesn't matter whether or not a QSO you and another 
station have made has been confirmed on eQSL (or via email or even 
good old-fashioned cardboard). "Confirming" it in your own log just 
says that you are comfortable that it's been confirmed. The confirmed 
flag in your log has no bearing on the information that's uploaded to 
the LoTW. The only way that LoTW will consider a QSO to be confirmed 
is if both parties have uploaded their properly signed (with their 
private keys) logs to LoTW and there are matching QSO records.

         The private key is only used to sign your log so that the 
LoTW server can be sure that it was really you who uploaded the QSO 
information, and not anyone else.

         There's a good article in the September 2005 QST by Ward, 
N0AX, which is also available on the ARRL website as a PDF file: 
http://www.arrl.org/lotw/silver.pdf that explains the whole process 
in some detail. Hopefully Ward's writeup will help you to understand 
the process and why "forging" in the way that you've described just 
isn't an easy thing to do. (I'll never say that it's impossible, but 
it certainly would not be trivial).

         73,
                 David, K2DBK
