description: >-
  OpenIO SDS exposes object storage through an S3-compatible gateway and an
  OpenStack Swift-compatible gateway. Authentication is therefore whatever the
  chosen gateway protocol defines: AWS Signature (v2 and v4) for the S3 gateway,
  and Swift auth (Keystone / TempAuth) for the Swift gateway. There is no
  provider-published OpenAPI, so this profile is derived from the documentation
  rather than from a machine-readable security scheme.
summary:
  types: [awsSignature, swiftAuth]
  api_key_in: [header]
  oauth2_flows: []
schemes:
  - name: s3-aws-signature-v4
    type: awsSignature
    scheme: aws-sigv4
    detail: >-
      S3 gateway authenticates requests with AWS Signature Version 4 (and
      legacy Signature Version 2). Both path-style and host-style (virtual
      hosted) bucket addressing are supported.
    credentials: S3 access key id + secret access key

  - name: swift-auth
    type: swiftAuth
    scheme: keystone-or-tempauth
    detail: >-
      Swift gateway authenticates via OpenStack Keystone tokens or TempAuth,
      per the OpenStack Swift API it is compatible with.

notes: >-
  OpenIO SDS is self-hosted software (acquired by OVHcloud in 2020); the S3/Swift
  gateway endpoint is deployment-specific, so there is no single hosted base URL.
