======================================================================

To use obfs4 as a Bridge Client, please add the following configuration
to your '%%PREFIX%%/etc/tor/torrc' config file:

ClientTransportPlugin obfs4 exec %%PREFIX%%/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 %%PREFIX%%/bin/obfs4proxy managed

# 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 0.0.0.0:443

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.

For more information, please consulte the official wiki page at 
https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/obfs4proxy

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