provider: SpiderOak
api: Aranya Client API
note: 'Aranya has no HTTP surface and therefore no OpenAPI securitySchemes, no API keys, no bearer tokens and no
  OAuth. Its authentication model is cryptographic and peer-to-peer: every device carries a key bundle and a device
  identity, teams are created and joined with a QUIC sync seed, and peer sync is authenticated with certificate-based
  mTLS as of v7.0.1. Authorization is policy-evaluated RBAC/ABAC on the Aranya graph. This artifact is written from
  the provider''s own docs and the published C header, not derived from a spec.'
schemes:
- id: device-key-bundle
  type: cryptographic-identity
  description: Each Aranya device generates and holds a key bundle; the daemon generates and maintains the cryptographic
    keys used to encrypt and decrypt data for Aranya and Fast Channels. The device identity (AranyaDeviceId) is
    derived from it.
  operations:
  - aranya_get_key_bundle
  - aranya_get_public_key_bundle
  - aranya_get_device_id
  - aranya_team_device_keybundle
  - aranya_team_device_public_key_bundle
- id: quic-sync-psk-seed
  type: pre-shared-key
  description: Joining or creating a team over the QUIC syncer requires a sync seed. A team creator generates one
    (aranya_create_team_quic_sync_config_generate) or supplies raw seed IKM; a joining device supplies the wrapped
    seed. The glossary defines PSK as "a key shared by two parties. The QUIC syncer uses PSKs instead of certificates."
    Seed length is fixed at ARANYA_SEED_IKM_LEN (32 bytes).

- id: mtls-sync
  type: mutual-tls
  description: 'v7.0.1 (2026-08-12) changed peer sync to use certificate-based mTLS ("use certificate-based mTLS
    for sync", PR #786). A certificate generation tool (aranya-certgen) was introduced in v5.0.0. See also the published
    mTLS specification at https://aranya-project.github.io/mtls/.'
  since: v7.0.1
  operations: []
- id: daemon-uds
  type: local-ipc
  description: 'The client authenticates to nothing over the network to reach the daemon: it connects to a local
    Unix domain socket whose path the caller sets explicitly. Trust is filesystem-scoped. A failure to reach it
    returns ARANYA_ERROR_IPC.'
  operations:

authorization:
  model: policy-evaluated RBAC with rank-based authorization, plus label-based ABAC segmentation
  description: Roles and permissions are defined in the Aranya policy language and evaluated by the policy VM. v4.0.0
    introduced custom roles with a default set initialized by setup_default_roles(); v6.0.0 changed custom roles
    to numerical rank-based authorization. Labels bind a data-plane channel to a set of policy rules, extending
    graph authority into the data plane.
