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.
