Implementation of the Noise Protocol Framework in Rust. A continuation of trevp's screech.
All basic patterns and XXfallback are implemented. Vectors from
noise-c and cacophony are passed.
Please test and review.
Perhaps don't use for security critical purposes (yet)!
The noise-protocol crate contains the abstract implementation of the
protocol framework. Several sibling crates, namely
noise-sodiumoxide, noise-ring and noise-rust-crypto, provide
implementations of the crypto primitives needed by
noise-protocol. They are wrappers around sodiumoxide, ring and
rust-crypto, respectively.
The following table shows what primitives each of these crates supports:
| | X25519 | AES-256-GCM | Chacha20-Poly1305 | SHA-256 | SHA-512 | BLAKE2s | BLAKE2b | |-------------|:------:|:-----------:|:-----------------:|:-------:|:-------:|:-------:|:-------:| | ring | | ✔ | ✔ | ✔ | ✔ | | | | sodiumoxide | ✔ | | | ✔ | ✔ | | ✔ | | rust-crypto | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ |
Although rust-crypto supports all primitives, it “has not been
thoroughly audited for correctness”, “so any use where security is
important is not recommended at this time”.
And you are not restricted to these libraries. You can easily plug in
other libraries by implementing the DH, Cipher and Hash traits.
