swarmauri_cipher_suite_cnsa20 0.2.0.dev5

CNSA 2.0 policy cipher suite with classical and post-quantum algorithms

---

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

pip install swarmauri_cipher_suite_cnsa20

Poetry

poetry add swarmauri_cipher_suite_cnsa20

uv

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

uv add swarmauri_cipher_suite_cnsa20

Or install it into the active environment:

uv pip install swarmauri_cipher_suite_cnsa20

Usage

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.
