swarmauri_certs_composite 0.11.0.dev1

Feature-routing certificate service for Swarmauri

Swarmauri Certs Composite

CompositeCertService is a lightweight router that coordinates multiple certificate providers behind a single facade. Configure it with the services you already have (self-signed, ACME, Vault, PKCS#11, etc.) and the composite chooses the right backend based on the feature you request.

Highlights

• Compose any ICertService implementations into one entry point.
• Route automatically by declared capability or override explicitly per call.
• Inspect supported features at runtime to drive UI/UX decisions.
• Ship as the default swarmauri.certs plugin named CompositeCertService.

Installation

Choose the tool that matches your workflow:

# pip
pip install swarmauri_certs_composite

# Poetry
poetry add swarmauri_certs_composite

# uv
uv add swarmauri_certs_composite

Quickstart

The composite accepts a sequence of certificate service implementations and routes each call to the first provider that advertises a matching capability. Below is a self-contained example that you can run with python quickstart.py.

import asyncio

from swarmauri_certs_composite import CompositeCertService
from swarmauri_base.certs.CertServiceBase import CertServiceBase


class SelfSignedOnly(CertServiceBase):
    def supports(self):
        return {"features": ("self_signed",)}

    async def create_self_signed(self, key, subject, **kw):
        return b"self-signed-cert"


class PrimaryCSR(CertServiceBase):
    def supports(self):
        return {"features": ("csr",)}

    async def create_csr(self, key, subject, **kw):
        return b"primary-csr"


class SecondaryCSR(CertServiceBase):
    def supports(self):
        return {"features": ("csr",)}

    async def create_csr(self, key, subject, **kw):
        return b"secondary-csr"


async def main():
    svc = CompositeCertService([SelfSignedOnly(), PrimaryCSR(), SecondaryCSR()])

    features = svc.supports()["features"]
    print("Advertised features:", sorted(features))

    cert = await svc.create_self_signed("key", {"CN": "example"})
    print("Self-signed cert:", cert)

    csr = await svc.create_csr("key", {"CN": "example"})
    print("CSR from primary provider:", csr)

    csr_override = await svc.create_csr(
        "key", {"CN": "example"}, opts={"backend": "SecondaryCSR"}
    )
    print("CSR via explicit backend override:", csr_override)


if __name__ == "__main__":
    asyncio.run(main())

supports() aggregates the advertised features of all child providers so callers can inspect available capabilities before invoking them. Passing opts={"backend": "ProviderType"} overrides the automatic routing when you need to target a specific provider.
