swarmauri_certs_remote_ca 0.3.0.dev3

Remote CA certificate service for Swarmauri

Swarmauri Remote CA Cert Service

A certificate enrollment bridge implementing the ICertService interface and forwarding CSRs to a remote Certificate Authority.

Features:

• Posts CSRs to a remote endpoint and returns issued certificates.
• Minimal parsing helpers for certificate snippets.
• Designed around X.509 as defined in RFC 5280 and Enrollment over Secure Transport (EST) in RFC 7030.

Installation

pip install swarmauri_certs_remote_ca

Entry Point

The service registers under the swarmauri.certs entry point as RemoteCaCertService.

Usage

The service is asynchronous and expects an existing CSR (certificate signing request) in PEM or DER form. Configure the remote CA endpoint and submit the CSR to receive the issued certificate:

import asyncio
import base64
import json
import httpx
from swarmauri_certs_remote_ca import RemoteCaCertService

csr = b"example-csr"
cert_bytes = b"example-cert"


async def main() -> None:
    async def handler(request: httpx.Request) -> httpx.Response:
        data = json.loads(request.content)
        assert base64.b64decode(data["csr"]) == csr
        return httpx.Response(200, json={"cert": base64.b64encode(cert_bytes).decode()})

    transport = httpx.MockTransport(handler)
    svc = RemoteCaCertService("https://ca.example/sign")
    svc._client = httpx.AsyncClient(transport=transport)

    cert = await svc.sign_cert(csr, {"kind": "dummy"})
    print(cert)


asyncio.run(main())

The example above mocks a CA using httpx.MockTransport. In real scenarios RemoteCaCertService posts the CSR to the configured endpoint and returns the certificate bytes supplied by the remote CA.
