Whisper

Wisp protocol client that exposes the Wisp connection over a TUN device.

When is this useful?

Many instutions are employing NGFW (Next Generation Firewall) technlogy that can identify and block encrypted VPN traffic through the use of DPI (deep packet inspection). To circumvent this, Whisper can be used to create a TUN device that routes all internet traffic through a select Wisp server. All traffic will be undifferentiable from typical WebSocket traffic.
