Hi,

here you can find the PT and their specifications:

Yes, there are implementations of PT 2.0 and 2.1 specifications. One of the criteria that we have adopted in the 2.1 specification process is that proposals need to have an implementation available before they can be considered for inclusion in a release of the specification.

Tor uses the part of the specification known as the Dispatcher IPC Interface to control a Pluggable Transport provider (known as a dispatcher) running in a separate process. The 2.0 and 2.1 versions of this protocol are compatible.

You can find a dispatcher implementation which conforms to the 2.1 specification and is backwards-compatible with the 2.0 Dispatcher IPC Interface specification here: https://github.com/OperatorFoundation/shapeshifter-dispatcher This dispatcher implementation currently provides the obfs2, obfs4, and Shadowsocks transports.

At one point, we (Operator Foundation) provided a patch to Tor implementing the 2.0 Dispatcher IPC Interface. You can find the fork here: https://oniongit.eu/nickm/tor/tree/dasyatid-rtt2017 You can find the associated Trac ticket here: https://trac.torproject.org/projects/tor/ticket/21816

Operator Foundation does not currently have any plans to commit additional resources to the Tor patch, but it is there as a starting point if anyone is interested in pursuing the project of updating Tor to conform to the PT 2.0 (and 2.1) protocol. We will be continuing to update the dispatcher implementation to match the specification as it evolves, as well as adding new transports as they are developed.

Is there any code that implements version 2.0 or 2.1 of these specs?

Tor currently implements the PT 1.0 specification: https://github.com/Pluggable-Transports/Pluggable-Transports-spec/blob/maste...
