Configuration

apkit's behavior is configured through the apkit.config.AppConfig class. Currently, the main configuration option is actor_keys.

You should provide an async function to actor_keys that returns the private keys for the actors managed by your server. This function is called whenever apkit needs to sign an activity before sending it to another server.

from apkit.config import AppConfig
from apkit.server.types import ActorKey

# This function is responsible for returning the appropriate
# private key based on the request context.
async def get_my_actor_keys(identifier: str) -> list[ActorKey]:
    # ... Logic to fetch keys from a database or elsewhere ...
    if identifier == "user123":
        return [ActorKey(key_id="https://example.com/users/user123#main-key", private_key=...)]
    return []

app_config = AppConfig(
    actor_keys=get_my_actor_keys
)

app = ActivityPubServer(apkit_config=app_config)
