# Tafrah

[![CI](https://github.com/perkamindo/tafrah/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/perkamindo/tafrah/actions/workflows/ci.yml)

Tafrah is a Rust-native post-quantum cryptography workspace covering [FIPS `203`, `204`, and `205`](https://csrc.nist.gov/Projects/post-quantum-cryptography) together with [FIPS `206` and `207`](https://csrc.nist.gov/projects/post-quantum-cryptography/post-quantum-cryptography-standardization/selected-algorithms), which NIST lists as selected algorithms with `FIPS coming soon` status.

The repository is organized around three layers:

- Native Rust crates for Rust consumers and `no_std`-friendly core implementations.
- An installable C ABI in `tafrah-abi` for language wrappers and systems integration across the
  implemented ML-KEM, ML-DSA, SLH-DSA, Falcon, and HQC parameter sets exposed by the workspace.
- UniFFI bindings and example wrappers for higher-level host integrations.

## Library Layout

- `tafrah/`: umbrella crate for Rust consumers.
- `tafrah-ml-kem/`: FIPS 203 ML-KEM.
- `tafrah-ml-dsa/`: FIPS 204 ML-DSA.
- `tafrah-slh-dsa/`: FIPS 205 SLH-DSA.
- `tafrah-falcon/`: FIPS 206 Falcon.
- `tafrah-hqc/`: FIPS 207 HQC.
- `tafrah-abi/`: installable C ABI and headers.
- `tafrah-uniffi/`: UniFFI-facing wrapper crate.
- `tafrah-math/`: shared finite-field, matrix, polynomial, and sampling primitives.
- `tafrah-traits/`: shared traits and common error surface.
- `examples/auth-demo/`: beginner-oriented cross-language implementation examples.
- `docs/`: architecture, integration, and API documentation.

## Quick Start

```sh
make test
make install PREFIX="$PWD/dist/install"
make examples
```

Common root targets:

- `make test`
- `make test-reference`
- `make test-deep-slh`
- `make coverage`
- `make build`
- `make build-abi`
- `make build-uniffi`
- `make install`
- `make examples`
- `make demo-python`
- `make generate-uniffi UNIFFI_LANGUAGE=python`

## Examples

Beginner-friendly examples and proof scripts live in
[examples/README.md](https://github.com/perkamindo/tafrah/blob/master/examples/README.md).

The primary example bundle is
[examples/auth-demo/README.md](https://github.com/perkamindo/tafrah/blob/master/examples/auth-demo/README.md).
It includes:

- a direct Rust crate example
- a Python `ctypes` wrapper
- C++, Go, Java, Kotlin, and JavaScript bindings over the C ABI
- a richer Python proof script for chat, file encryption, signatures, and small benchmarks

## Install Layout

`tafrah-abi` installs into a prefix with the following layout:

- `lib/libtafrah_abi.{so,dylib}` or `tafrah_abi.dll`
- `lib/libtafrah_abi.a` or `tafrah_abi.lib`
- `include/tafrah/tafrah.h`
- `include/tafrah/tafrah.hpp`
- `include/tafrah_abi.h`
- `include/tafrah_ffi.h` as a compatibility shim
- `lib/pkgconfig/tafrah.pc`

For a local install:

```sh
make install PREFIX="$PWD/dist/install"
```

## Prebuilt Releases And Source Builds

GitHub Release assets are architecture-specific. Current release packaging is
planned around:

- Linux `x86_64`
- Linux `aarch64`
- macOS `arm64`
- macOS `x86_64`
- Windows `x86_64`

If no prebuilt asset matches the target machine, build from source from the
repository root:

```sh
make test
make install PREFIX="$PWD/dist/install"
```

For Rust consumers, prefer the native crates from crates.io instead of the ABI
layer.

WARNING: FN-DSA (FIPS 206) and HQC (FIPS 207) have been selected by NIST but the standards are not yet finalized. This implementation follows the currently available specifications and may change once the official standards are published. Backward compatibility is not guaranteed.
