SSLv3/TLSv1 protocol are massively used.

In OpenVPN, if a user needs to access to a remote virtual address (address family matching

virtual network card), then OS will send the data packet (TUN mode) or data frame (TAP mode) to

the visual network card through routing mechanism. Upon the reception, service program will

receive and process those data and send them out through outer net by SOCKET, owing to which,

the remote service program will receive those data and carry out processing, then send them to

the virtual network card, then application software receive and accomplish a complete

unidirectional transmission, vice versa.
