What is Encryption?
Encryption is the process of encoding data so that only a computer with the right decoder will be able to read and use it.
In a VPN, the computers at each end of the tunnel encrypt the
data entering the tunnel and decrypt it at the other end
What is Tunneling?
Tunnelling involves establishing and maintaining a logical network connection (that may contain intermediate hops).
On this connection, packets constructed in a specific VPN protocol format are encapsulated within some other base or carrier protocol, then transmitted between VPN client and server, and finally de-encapsulated on the receiving side.
