description: >-
  Authentication profile for the Univers EnOS platform APIs, assembled from the
  first-party SDKs on the EnvisionIot GitHub org and the EnOS API documentation
  (the docs host itself was unreachable from the probe location; SDK sources
  are the verified evidence). No OpenAPI document is published, so this profile
  is searched rather than derived from securitySchemes.

schemes:
  - name: EnOS service API request signing
    type: apiKey
    style: accessKey + secretKey HMAC-style request signature
    description: >-
      Applications are registered in the EnOS Application Portal / Developer
      Console to obtain an application accessKey and secretKey. Every EnOS
      Open API request is signed with these credentials; the service SDKs
      (com.envisioniot:enos-api for Java, enos-api-sdk-python and
      enos-poseidon for Python) generate the API request signature
      automatically and assemble the request URL against the per-environment
      API gateway address.

  - name: EnOS device connectivity (MQTT/HTTP device secrets)
    type: apiKey
    style: productKey/deviceKey/deviceSecret over MQTT or HTTP
    description: >-
      Devices connect to EnOS Cloud through the MQTT or HTTP device SDKs using
      per-device credentials (product key, device key, device secret), with
      optional X.509 device certificates issued by the EnOS certificate
      service to secure device-to-cloud communication.

  - name: EnOS data subscription authentication
    type: apiKey
    style: accessKey + subscription id + signature (protobuf AuthReq)
    description: >-
      The data-subscription streaming protocol authenticates consumers with an
      AuthReq protobuf message carrying accessKey, subId, and a sign field
      (see grpc/univers-enos-subscription-sub.proto, harvested verbatim from
      the first-party Python subscription SDK).
