create(parent, attestorId=None, body=None, x__xgafv=None)

Creates an attestor, and returns a copy of the new attestor. Returns `NOT_FOUND` if the project does not exist, `INVALID_ARGUMENT` if the request is malformed, `ALREADY_EXISTS` if the attestor already exists.

delete(name, x__xgafv=None)

Deletes an attestor. Returns `NOT_FOUND` if the attestor does not exist.

get(name, x__xgafv=None)

Gets an attestor. Returns `NOT_FOUND` if the attestor does not exist.

getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

list(parent, pageSize=None, pageToken=None, x__xgafv=None)

Lists attestors. Returns `INVALID_ARGUMENT` if the project does not exist.

list_next()

Retrieves the next page of results.

setIamPolicy(resource, body=None, x__xgafv=None)

Sets the access control policy on the specified resource. Replaces any existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors.

testIamPermissions(resource, body=None, x__xgafv=None)

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a `NOT_FOUND` error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

update(name, body=None, x__xgafv=None)

Updates an attestor. Returns `NOT_FOUND` if the attestor does not exist.

validateAttestationOccurrence(attestor, body=None, x__xgafv=None)

Returns whether the given `Attestation` for the given image URI was signed by the given `Attestor`

create(parent, attestorId=None, body=None, x__xgafv=None)
Creates an attestor, and returns a copy of the new attestor. Returns `NOT_FOUND` if the project does not exist, `INVALID_ARGUMENT` if the request is malformed, `ALREADY_EXISTS` if the attestor already exists.

Args:
  parent: string, Required. The parent of this attestor. (required)
  body: object, The request body.
    The object takes the form of:

{ # An attestor that attests to container image artifacts. An existing attestor cannot be modified except where indicated.
  "description": "A String", # Optional. A descriptive comment. This field may be updated. The field may be displayed in chooser dialogs.
  "etag": "A String", # Optional. A checksum, returned by the server, that can be sent on update requests to ensure the attestor has an up-to-date value before attempting to update it. See https://google.aip.dev/154.
  "name": "A String", # Required. The resource name, in the format: `projects/*/attestors/*`. This field may not be updated.
  "updateTime": "A String", # Output only. Time when the attestor was last updated.
  "userOwnedGrafeasNote": { # An user owned Grafeas note references a Grafeas Attestation.Authority Note created by the user. # This specifies how an attestation will be read, and how it will be used during policy enforcement.
    "delegationServiceAccountEmail": "A String", # Output only. This field will contain the service account email address that this attestor will use as the principal when querying Container Analysis. Attestor administrators must grant this service account the IAM role needed to read attestations from the note_reference in Container Analysis (`containeranalysis.notes.occurrences.viewer`). This email address is fixed for the lifetime of the attestor, but callers should not make any other assumptions about the service account email; future versions may use an email based on a different naming pattern.
    "noteReference": "A String", # Required. The Grafeas resource name of a Attestation.Authority Note, created by the user, in the format: `projects/*/notes/*`. This field may not be updated. An attestation by this attestor is stored as a Grafeas Attestation.Authority Occurrence that names a container image and that links to this Note. Grafeas is an external dependency.
    "publicKeys": [ # Optional. Public keys that verify attestations signed by this attestor. This field may be updated. If this field is non-empty, one of the specified public keys must verify that an attestation was signed by this attestor for the image specified in the admission request. If this field is empty, this attestor always returns that no valid attestations exist.

Binary Authorization computes this ID as the OpenPGP RFC4880 V4 fingerprint, represented as upper-case hex. If `id` is provided by the caller, it will be overwritten by the API-calculated ID.
        "comment": "A String", # Optional. A descriptive comment. This field may be updated.

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).
  "bindings": [ # Associates a list of `members`, or principals, with a `role`. Optionally, may specify a `condition` that determines how and when the `bindings` are applied. Each of the `bindings` must contain at least one principal. The `bindings` in a `Policy` can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.
    { # Associates `members`, or principals, with a `role`.
      "condition": { # Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec. Example (Comparison): title: "Summary size limit" description: "Determines if a summary is less than 100 chars" expression: "document.summary.size() < 100" Example (Equality): title: "Requestor is owner" description: "Determines if requestor is the document owner" expression: "document.owner == request.auth.claims.email" Example (Logic): title: "Public documents" description: "Determine whether the document should be publicly visible" expression: "document.type != 'private' && document.type != 'internal'" Example (Data Manipulation): title: "Notification string" description: "Create a notification string with a timestamp." expression: "'New message received at ' + string(document.create_time)" The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information. # The condition that is associated with this binding. If the condition evaluates to `true`, then this binding applies to the current request. If the condition evaluates to `false`, then this binding does not apply to the current request. However, a different role binding might grant the same role to one or more of the principals in this binding. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

Does not include identities that come from external identity providers (IdPs) through identity federation. * `user:{emailid}`: An email address that represents a specific Google account. For example, `alice@example.com` . * `serviceAccount:{emailid}`: An email address that represents a Google service account.

For example, `alice@example.com?uid=123456789012345678901`. If the user is recovered, this value reverts to `user:{emailid}` and the recovered user retains the role in the binding. * `deleted:serviceAccount:{emailid}?uid={uniqueid}`: An email address (plus unique identifier) representing a service account that has been recently deleted. For example, `my-other-app@appspot.gserviceaccount.com?uid=123456789012345678901`. If the service account is undeleted, this value reverts to `serviceAccount:{emailid}` and the undeleted service account retains the role in the binding. * `deleted:group:{emailid}?uid={uniqueid}`: An email address (plus unique identifier) representing a Google group that has been recently deleted. For example, `admins@example.com?uid=123456789012345678901`.

This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

list(parent, pageSize=None, pageToken=None, x__xgafv=None)
Lists attestors. Returns `INVALID_ARGUMENT` if the project does not exist.

Args:
  parent: string, Required. The resource name of the project associated with the attestors, in the format `projects/*`. (required)
  pageSize: integer, Requested page size. The server may return fewer results than requested. If unspecified, the server will pick an appropriate default.
  pageToken: string, A token identifying a page of results the server should return. Typically, this is the value of ListAttestorsResponse.next_page_token returned from the previous call to the `ListAttestors` method.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

This field will contain the service account email address that this attestor will use as the principal when querying Container Analysis. Attestor administrators must grant this service account the IAM role needed to read attestations from the note_reference in Container Analysis (`containeranalysis.notes.occurrences.viewer`). This email address is fixed for the lifetime of the attestor, but callers should not make any other assumptions about the service account email; future versions may use an email based on a different naming pattern.

  "policy": { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`.

If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

testIamPermissions(resource, body=None, x__xgafv=None)
Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a `NOT_FOUND` error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Args:
  resource: string, REQUIRED: The resource for which the policy detail is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for `TestIamPermissions` method.
  "permissions": [ # The set of permissions to check for the `resource`. Permissions with wildcards (such as `*` or `storage.*`) are not allowed. For more information see [IAM Overview](https://cloud.google.com/iam/docs/overview#permissions).
    "A String",
  ],
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format

Returns:
  An object of the form:

    { # Response message for `TestIamPermissions` method.
  "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is allowed.
    "A String",
  ],

validateAttestationOccurrence(attestor, body=None, x__xgafv=None)
Returns whether the given `Attestation` for the given image URI was signed by the given `Attestor`

Args:
  attestor: string, Required. The resource name of the Attestor of the occurrence, in the format `projects/*/attestors/*`. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for ValidationHelperV1.ValidateAttestationOccurrence.
  "attestation": { # Occurrence that represents a single "attestation". The authenticity of an attestation can be verified using the attached signature. If the verifier trusts the public key of the signer, then verifying the signature is sufficient to establish trust. In this circumstance, the authority to which this attestation is attached is primarily useful for lookup (how to find this attestation if you already know the authority and artifact to be verified) and intent (for which authority this attestation was intended to sign. # Required. An AttestationOccurrence to be checked that it can be verified by the `Attestor`. It does not have to be an existing entity in Container Analysis. It must otherwise be a valid `AttestationOccurrence`.
    "jwts": [ # One or more JWTs encoding a self-contained attestation. Each JWT encodes the payload that it verifies within the JWT itself. Verifier implementation SHOULD ignore the `serialized_payload` field when verifying these JWTs. If only JWTs are present on this AttestationOccurrence, then the `serialized_payload` SHOULD be left empty. Each JWT SHOULD encode a claim specific to the `resource_uri` of this Occurrence, but this is not validated by Grafeas metadata API implementations. The JWT itself is opaque to Grafeas.

      { # Verifiers (e.g. Kritis implementations) MUST verify signatures with respect to the trust anchors defined in policy (e.g. a Kritis policy). Typically this means that the verifier has been configured with a map from `public_key_id` to public key material (and any required parameters, e.g. signing algorithm). In particular, verification implementations MUST NOT treat the signature `public_key_id` as anything more than a key lookup hint. The `public_key_id` DOES NOT validate or authenticate a public key; it only provides a mechanism for quickly selecting a public key ALREADY CONFIGURED on the verifier through a trusted channel. Verification implementations MUST reject signatures in any of the following circumstances: * The `public_key_id` is not recognized by the verifier. * The public key that `public_key_id` refers to does not verify the signature with respect to the payload. The `signature` contents SHOULD NOT be "attached" (where the payload is included with the serialized `signature` bytes). Verifiers MUST ignore any "attached" payload and only verify signatures with respect to explicitly provided payload (e.g. a `payload` field on the proto message that holds this Signature, or the canonical serialization of the proto message that holds this signature).
        "publicKeyId": "A String", # The identifier for the public key that verifies this signature. * The `public_key_id` is required. * The `public_key_id` SHOULD be an RFC3986 conformant URI. * When possible, the `public_key_id` SHOULD be an immutable reference, such as a cryptographic digest. Examples of valid `public_key_id`s: OpenPGP V4 public key fingerprint: * "openpgp4fpr:74FAF3B861BDA0870C7B6DEF607E48D2A663AEEA" See https://www.iana.org/assignments/uri-schemes/prov/openpgp4fpr for more details on this scheme.

        "signature": "A String", # The content of the signature, an opaque bytestring. The payload that this signature verifies MUST be unambiguously provided with the Signature during verification. A wrapper message might provide the payload explicitly. Alternatively, a message might have a canonical serialization that can always be unambiguously computed to derive the payload.
