Technical inquiry about tor-ptmgr of Arti
by pryty 05 Jul '26

05 Jul '26

Dear list, I'm writing a technical inquiry about tor-ptmgr. Although the issue #666 ( https://gitlab.torproject.org/tpo/core/arti/-/work_items/666 ) said that: " Some people would like to use pluggable transports in a context other than inside a Tor process for making Channels. Right now, ptmgr contemplates this but does not actually provide an API for it.", I saw that: ```rust #[tokio::main] asyncfnmain() ->Result<()> { tracing_subscriber::fmt::init(); letcommon_params=PtCommonParameters::builder() .state_location("/tmp/arti-pt".into()) .build() .unwrap(); letclient_params=PtClientParameters::builder() .transports(vec!["obfs4".parse().unwrap()]) .build() .unwrap(); letmutpt= PluggableClientTransport::new("./obfs4proxy".into(), vec![], common_params, client_params); pt.launch(PreferredRuntime::current()?).await?; loop { info!("message: {:?}", pt.next_message().await?); } } ``` at .crates\tor-ptmgr\examples\run-pt.rs which seems like it should actually work without tor. Does this example already intended a public API for using pluggable transports independently of Tor? If yes, why this issue is still open. I'd appreciate any clarification. Thank you. pryty26 pryty017(a)proton.me Sent with [Proton Mail](https://proton.me/mail/home) secure email.

[Proposal for Arti] Add REALITY as an optional pluggable transport for Arti
by pryty 01 Jul '26

01 Jul '26

Hi, dear developers and tor-dev I have been following the development of Arti closely and would like to suggest a new and modern feature: Adding support for the REALITY protocol as a optional new PT protocol in Arti. I suggest REALITY as a new optional protocol, since REALITY unlike traditional PTs which rely on traffic obfuscation or domain fronting, REALITY borrows real TLS sessions from existing websites, which could be very useful for Tor users, who needs to bypass DPI. Additionally, I would be willing to work on this new feature, if it's acceptable to you. However, in my opinion, it could be implemented as an new PT plugin via tor-ptmgr, with corresponding configuration changes in arti-client. I look forward to your feedback.
