Hi!
I have question about security of VPN client.
Let say I have Note with VPN client and public WIFI like regular library or cafeteria.
So when I will turn on network connection first thing start is a VPN client will send open security key to remote server.
And in this moment it possible to man-in-middle just intercept this initialization message and so no security.
Sorry for stupid question but it reasonable correct ?

Re: Security question about VPN and Public WiFi
Sorry, but what is an open security key? Your VPN login details? In that case, they "should" be encrypted with SSL.

If there is signature verification, it should be safe.
