if that the case you dont want vpn nor ipsec nor ssh tunneling, then, you
have to encrypt/decrypt your data between  application layer (layer 7) and
transport layer (layer 4).

application data (userland) --> encrypt and send data thru socket
(userland) --> transport layer (kernel area)

it depends on what kind of encryption algorithm you are going to use... here
is a free source code of blowfish if you like this algorithm:
