Reads the private JWK from a JSON file on disk.
Options
:path(required) — absolute path to the JWK JSON file.:cache— seeOpenFeed.KeyStore. Defaults totrue.
Multi-node warning
This store is not multi-node safe unless the path is genuinely shared
storage. Each node reads its own filesystem, so if the file differs — or was
generated separately per node — proofs get signed with keys OpenFeed has
never seen. Use OpenFeed.KeyStore.Env or AshOpenFeed.KeyStore.Ash for
anything running more than one instance.
Written files are 0600, and the parent directory is created if needed.
