Tunnel port to port site visitors by way of an obfuscated channel with AES-GCM encryption.
Obfuscation Modes
- Session Cookie HTTP GET (http-client)
- Set-Cookie Session Cookie HTTP/2 200 OK (http-server)
- WebSocket Handshake “Sec-WebSocket-Key” (websocket-client)
- WebSocket Handshake “Sec-WebSocket-Settle for” (websocket-server)
- No obfuscation, simply use AES-GCM encrypted messages (none)
AES-GCM is enabled by default for every of the choices above.
Utilization
[email protected]:/decide/gohide-dev# ./gohide -h
Utilization of ./gohide:
-f string
hear faux server -r x.x.x.x:xxxx (ip/area:port) (default "0.0.0.0:8081")
-key openssl passwd -1 -salt okay | md5sum
aes encryption secret: use '-k openssl passwd -1 -salt okay | md5sum' to derive key from password (default "5fe10ae58c5ad02a6113305f4e702d07")
-l string
hear port ahead -l x.x.x.x:xxxx (ip/area:port) (default "127.0.0.1:8080")
-m string
obfuscation mode (AES encrypted by default): websocket-client, websocket-server, http-client, http-server, none (default "none")
-pem string
path to .pem for TLS encryption mode: default = use hardcoded key pair 'CN:goal.com', none = plaintext mode (default "default")
-r string
ahead to distant faux server -r x.x.x.x:xxxx (ip/area:port) (default "127.0.0.1:9999")Situation
