ring

ring is focused on the implementation, testing, and optimization of a core set of cryptographic operations exposed via an easy-to-use (and hard-to-misuse) API. ring exposes a Rust API and is written in a hybrid of Rust, C, and assembly language.

Particular attention is being paid to making it easy to build and integrate ring into applications and higher-level frameworks, and to ensuring that ring works optimally on small devices, and eventually microcontrollers, to support Internet of Things (IoT) applications.

Most of the C and assembly language code in ring comes from BoringSSL, and BoringSSL is derived from OpenSSL. ring merges changes from BoringSSL regularly. Also, several changes that were developed for ring have been contributed to and integrated into BoringSSL.

Documentation

See the documentation at https://docs.rs/ring/latest/ring/.

See [BUILDING.md](BUILDING.md) for instructions on how to build it. These instructions are especially important for cross-compiling and for building on Windows when not building from crates.io, as there are build prerequisites that need to be installed.

Benchmarks

ring's benchmarks are located in the benches folder of this repository. Because there is lots of platform-specific code in ring, and because ring chooses dynamically at runtime which optimized implementation of each crypto primitive to use, it is very difficult to publish a useful single set of benchmarks; instead, you are highly encouraged to run the benchmarks yourselves on your target hardware.

Contributing

The most important contributions are uses of ring. That is, we're very interested in seeing useful things built on top of ring, like implementations of TLS, SSH, the Noise Protocol, etc.

The ring project happily accepts pull requests. The portions of pull requests that modify existing files must be licensed under the same terms as the files being modified. New files in pull requests, including in particular all Rust code, must be licensed under the ISC-style license. Please state that you agree to license your contributions in the commit messages of commits in pull requests by putting this at the bottom of your commit message:


I agree to license my contributions to each file under the terms given
at the top of each file I changed.

Minimum Supported Rust Version (MSRV)

ring is tested on the latest Stable, Beta, and Nightly releases of Rust, as well as the oldest version known to work according to the tests run in CI. That oldest version known to work is documented as the MSRV in [Cargo.toml](Cargo.toml).

Bug Reporting

Please report bugs either as pull requests or as issues in the issue tracker. ring has a full disclosure vulnerability policy. Please do NOT attempt to report any security vulnerability in this code privately to anybody.
