Advanced Crypto Library for Rust

This library is a partial porting of DEDIS kyber library to pure Rust.

This library provides a toolbox of advanced cryptographic primitives for Rust, that need more than straightforward signing and encryption. Please see the Rust crate documentation for this package for details on the library's purpose and API functionality.

The following table shows the already implemented features in compared with the DEDIS' library.

This first release's task is to provide DKG APIs intended to be used with Ed25519 Signature Scheme in a pure Rust implementation. Tests and benchmarks are also fully implemented.

A note on deriving shared secrets

Traditionally, ECDH (Elliptic curve Diffie-Hellman) derives the shared secret from the x point only. In this framework, you can either manually retrieve the value or use the MarshalBinary method to take the combined (x, y) value as the shared secret. We recommend the latter process for new softare/protocols using this framework as it is cleaner and generalizes across different types of groups (e.g., both integer and elliptic curves), although it will likely be incompatible with other implementations of ECDH. See the Wikipedia page on ECDH.

Reporting security problems

This library is offered as-is, and without a guarantee. It will need an independent security review before it should be considered ready for use in security-critical applications. If you integrate Kyber into your application it is YOUR RESPONSIBILITY to arrange for that audit.
