# Rust Cryptography Wrappers
This repository is parameter selection, lightweight wrapper and foreign function interface (FFI) around a number of Rust cryptographic libraries. Its purpose isn't to implement primitives, rather to unify the API surface of existing libraries; limited to the tiny subset needed by the Dark Bio project.
It contains the following primitives and parameters:
- **RSA** via `RSA2048`,
- **EdDSA** via `Ed25519`,
- **STREAM** via `ChaCha20` and `Poly1305` at `16B` tags and `64KiB` chunks,
- **HPKE** via `X25519`, `HKDF`, `SHA256`, `ChaCha20` and `Poly1305` at `dark-bio-v1:` info prefix.
