Enable CURVE encryption for VIP connections over TCP #93

Closed hashstat closed 9 years ago

hashstat commented 9 years ago

Currently, VOLTTRON does not encrypt traffic over VIP sockets. Ideally, anything over TCP should be considered untrusted and encrypted by default.

Previous commits enable ZeroMQ CURVE encryption by default for the router when bound to TCP addresses. This can be disabled for testing/development by setting the file _$VOLTTRONHOME/curve.key to a zero-length file: truncate --size 0 $VOLTTRON_HOME/curve.key.

The public key is printed to the log at INFO level in two formats on volttron start. The first format is Z85 and the second is a URL-safe base64 string. The latter may be used in addresses passed to agent constructors. See volttron/platform/vip/socket.py for more information.
