swarmauri_auth_idp_cognito 0.2.0.dev3

AWS Cognito OAuth 2.0 / OAuth 2.1 / OIDC 1.0 identity provider implementations for Swarmauri

---

Swarmauri Auth IDP Cognito

AWS Cognito OAuth 2.0, OAuth 2.1, and OIDC 1.0 login and app-client flows packaged for the Swarmauri ecosystem.

Features

• PKCE-enabled authorization code logins with signed state payloads to prevent tampering.
• Automatic discovery of Cognito endpoints with resilient HTTP retry semantics.
• ID token verification against Cognito JWKS with graceful fallback to the UserInfo endpoint.
• Machine-to-machine app clients supporting shared secrets or JWT-based client assertions.
• ComponentBase-registered classes for seamless Swarmauri plugin discovery and configuration.

Installation

pip

pip install swarmauri_auth_idp_cognito

uv (project)

uv add swarmauri_auth_idp_cognito

uv (environment)

uv pip install swarmauri_auth_idp_cognito

Usage

Instantiate the login classes with your Cognito issuer, app client credentials, and redirect URI. Persist the returned state between auth_url and exchange* calls to prevent replay attacks.

from pydantic import SecretBytes, SecretStr
from swarmauri_auth_idp_cognito import CognitoOAuth21Login

login = CognitoOAuth21Login(
    issuer="https://example-domain.auth.us-east-1.amazoncognito.com",
    client_id="example-client-id",
    client_secret=SecretStr("example-secret"),
    redirect_uri="https://example.com/callback",
    state_secret=SecretBytes(b"super-secret-state-key"),
)

# Within an async context:
# auth_payload = await login.auth_url()
# identity = await login.exchange_and_identity(code, auth_payload["state"])
print(login.client_id)

Expected Workflow

1. Call auth_url() and redirect the user agent to the returned authorization URL.
2. Persist the state value and later validate it when Cognito posts back to your callback.
3. Call exchange_and_identity() (or exchange() for the OIDC login) to normalize identity claims.
4. Use the normalized payload to provision sessions, issue downstream tokens, or audit login activity.

App client classes expose the same access_token coroutine to support background services and machine-to-machine integrations.
