You are wise. Yes, it does tend to flag you.
But a lot of people are using it now so that does help.
Your concern is one of the reasons the gov fought hard to keep net traffic unencrypted. They had to let SSL alone to facilitate web commerce. It would be so simple to have had the net fully encrypted...same story as with cell phones...they were terrified of strong encryption being used in that industry.
Thanks, I’ll bear that in mind.
