#[non_exhaustive]pub struct BridgesConfig { /* private fields */ }
Expand description
Configuration for anti-censorship features: bridges and pluggable transports.
A “bridge” is a relay that is not listed in the regular Tor network directory; clients use them to reach the network when a censor is blocking their connection to all the regular Tor relays.
A “pluggable transport” is a tool that transforms and conceals a user’s connection to a bridge; clients use them to reach the network when a censor is blocking all traffic that “looks like Tor”.
A BridgesConfig
configuration has the following pieces:
- A
BridgeList
ofBridgeConfig
s, which describes one or more bridges. - An
enabled
boolean to say whether or not to use the listed bridges. - A list of
pt::TransportConfig
s.
§Example
Here’s an example of building a bridge configuration, and using it in a TorClientConfig.
The bridges here are fictitious; you’ll need to use real bridges if you want a working configuration.
#[cfg(feature = "pt-client")]
use arti_client::config::{TorClientConfig, BridgeConfigBuilder, CfgPath};
// Requires that the pt-client feature is enabled.
use arti_client::config::pt::TransportConfigBuilder;
let mut builder = TorClientConfig::builder();
// Add a single bridge to the list of bridges, from a bridge line.
// This bridge line is made up for demonstration, and won't work.
const BRIDGE1_LINE : &str = "Bridge obfs4 192.0.2.55:38114 316E643333645F6D79216558614D3931657A5F5F cert=YXJlIGZyZXF1ZW50bHkgZnVsbCBvZiBsaXR0bGUgbWVzc2FnZXMgeW91IGNhbiBmaW5kLg iat-mode=0";
let bridge_1: BridgeConfigBuilder = BRIDGE1_LINE.parse()?;
// This is where we pass `BRIDGE1_LINE` into the BridgeConfigBuilder.
builder.bridges().bridges().push(bridge_1);
// Add a second bridge, built by hand. This way is harder.
// This bridge is made up for demonstration, and won't work.
let mut bridge2_builder = BridgeConfigBuilder::default();
bridge2_builder
.transport("obfs4")
.push_setting("iat-mode", "1")
.push_setting(
"cert",
"YnV0IHNvbWV0aW1lcyB0aGV5IGFyZSByYW5kb20u8x9aQG/0cIIcx0ItBcTqiSXotQne+Q"
);
bridge2_builder.set_addrs(vec!["198.51.100.25:443".parse()?]);
bridge2_builder.set_ids(vec!["7DD62766BF2052432051D7B7E08A22F7E34A4543".parse()?]);
// Now insert the second bridge into our config builder.
builder.bridges().bridges().push(bridge2_builder);
// Now configure an obfs4 transport. (Requires the "pt-client" feature)
let mut transport = TransportConfigBuilder::default();
transport
.protocols(vec!["obfs4".parse()?])
// Specify either the name or the absolute path of pluggable transport client binary, this
// may differ from system to system.
.path(CfgPath::new("/usr/bin/obfs4proxy".into()))
.run_on_startup(true);
builder.bridges().transports().push(transport);
let config = builder.build()?;
// Now you can pass `config` to TorClient::create!
You can also find an example based on snowflake in arti-client example folder.
