I am a stupid questions and a inexperienced computer user, my question is the following:

 

can outsider with a copy a key without lan network pasword can use the key alone and get to sync my folder's files?

 

In other words, I stored my keys in gmail contacts, if a gmail employee get the keys and outside my network in the internet, can he/she by simply the key and enter it in his/her's bittorrentsync program gui and get in and sync my files?? What if he or she successfully hecks into my modem/network, would that key connects my folders with his/her bittorrentsync programs and related foloders?

This has nothing to do with uTorrent.
