# Swarmauri Cipher Cnsa20

CNSA 2.0-aligned cipher suite skeleton for high-assurance deployments.

## Features

- Enumerates classical (ES384/PS384) and post-quantum (ML-DSA, SLH-DSA, ML-KEM)
  selections from the CNSA 2.0 profile
- Surfaces NIST security level metadata for ML-DSA, SLH-DSA, and ML-KEM
  algorithms to support downstream policy checks
- Provides consistent normalization across signing, encryption, and key
  encapsulation operations with JWA and provider dialect mappings

## Installation

### pip

```bash
pip install swarmauri_cipher_suite_cnsa20
```

### Poetry

```bash
poetry add swarmauri_cipher_suite_cnsa20
```

### uv

To add the dependency to a `pyproject.toml` managed by `uv`:

```bash
uv add swarmauri_cipher_suite_cnsa20
```

Or install it into the active environment:

```bash
uv pip install swarmauri_cipher_suite_cnsa20
```

## Usage

```python
from swarmauri_cipher_suite_cnsa20 import Cnsa20CipherSuite

suite = Cnsa20CipherSuite(name="demo-cnsa20")

# Inspect the available operations and defaults
print(suite.features()["ops"].keys())

# Normalize a post-quantum signing request
descriptor = suite.normalize(op="sign", alg="ML-DSA-65")
print(descriptor["alg"], descriptor["constraints"]["nistLevel"])  # -> 3
```

The suite returns normalized descriptors that include canonical algorithm names,
per-dialect mappings, and policy metadata so providers can focus on execution.

## Entry Point

The suite registers under the `swarmauri.cipher_suites` entry point as `Cnsa20CipherSuite`.
