Here's what I know about encryption.. The day to day civilian can't do much to another civilian or institution with proper encryption..BUT,the us govt can...
There are laws requiring all codes and encryptions be 'crackable' or translation keys on file by the govt..in turn,the govt has its own encryption technology that is not availabile to the public,ALTHOUGH, the same technology may be public in another country..meaning its just for uncle Sam in the states..but China might be using the same technology for public affairs security..
So,if you're hiding top secret company files like in a movie,average Joe can't crack the admin code..uncle Sam has the codes cracked and on file...
Safe from ALMOST everything...
This may be a publicly known or little known bit of info,I got it from a friend who works closely with the govt and his company involving communications..he explained it after I got an encryption text app for my phone...
