This repository contains multiple related crates implementing the lyrebird (obfs4) library, lyrebird binary, and Pluggable Transports in Rust (PTRS) library.

Crate	Description	Crates.io	Docs
ptrs	A library supporting implementation and integration of Pluggable Transport protocols.
lyrebird	Implementation of the Lyrebird Tor bridge and a forward proxy compatible with ptrs.
obfs4	An implementation of obfs4 pluggable transport library in pure rust.

The planned Minimum Supported Rust Version (MSRV) is 1.60, however there is no current testing to ensure that this is working currently.

MSRV can be changed in the future, but it will be done with a minor version bump.

Things to keep an eye on:

• PR implementating elligator2 for the dalek ed25519 library. PR Here

Dual licensing under both MIT and Apache-2.0 is the currently accepted standard by the Rust language community and has been used for both the compiler and many public libraries since (see Why dual MIT/ASL2license?). In order to match the community standards, ptrs is using the dual MIT+Apache-2.0 license.
