        a "look-like nothing" obfuscation protocol for TCP

        Project homepage: https://gitlab.com/yawning/obfs4

        Description

        obfs4 (a.k.a. The Obfuscator) is a transport with the same features as ScrambleSuit but utilizing Dan Bernstein's elligator2 technique for public key obfuscation, and the ntor protocol for one-way authentication. This results in a faster protocol.

        | obfs4proxy on OpenBSD
        +-----------------------------------------------------------------------
        
        To use obfs4 as a Bridge Client, please add the following configuration
        to your 'torrc' config file:
        
        	ClientTransportPlugin obfs4 exec /usr/local/bin/obfs4proxy
        
        To enable this Pluggable Transport in your Tor Bridge, use the
        following configurations in your 'torrc' file:
        
        	# Use obfs4proxy to provide the obfuscator
        	ServerTransportPlugin obfs4 exec /usr/local/bin/obfs4proxy
        
        	# Enable Extended ORPort
        	ExtORPort auto
        
        	## (Optional) Listen on the specified IP:PORT for obfs4 connections
        	## as opposed to picking a random port automatically
        	# ServerTransportListenAddr obfs4 0.0.0.0:PORT
        
        obfs4proxy is backwards compatible with obfs2 and obfs3 either in
        client or server mode. If you want to use it like this, please adjust
        your 'torrc' config file to fit your needs. It's compatible with
        ScrambleSuit in client mode.
