swarmauri_cipher_suite_fips205 0.11.0.dev1

FIPS 205 SLH-DSA cipher suite bindings for Swarmauri

Swarmauri Cipher Suite FIPS 205

SLH-DSA (SPHINCS+) signature suite aligned with NIST FIPS 205.

Features

• Exposes all SHA2 and SHAKE based SLH-DSA parameter sets from the standard
• Provides security level metadata for downstream admission control
• Supplies provider-oriented descriptors for Swarmauri signing flows
• Publishes an entry point for automatic suite discovery and registration

Installation

pip

pip install swarmauri_cipher_suite_fips205

Poetry

poetry add swarmauri_cipher_suite_fips205

uv

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

uv add swarmauri_cipher_suite_fips205

Or install it into the active environment:

uv pip install swarmauri_cipher_suite_fips205

Usage

from swarmauri_cipher_suite_fips205 import Fips205CipherSuite

suite = Fips205CipherSuite(name="slhdsa")

# Normalise a SLH-DSA-SHAKE-192s signing request
descriptor = suite.normalize(op="sign", alg="SLH-DSA-SHAKE-192s")
print(descriptor["constraints"]["nistLevel"])  # -> 3
print(descriptor["mapped"]["provider"])       # -> slh-dsa:SLH-DSA-SHAKE-192s

Requests for non-SLH-DSA algorithms raise ValueError, surfacing the policy violation early.

Entry Point

The suite registers under the swarmauri.cipher_suites entry point as Fips205CipherSuite.
