Properties

Audience

The full resource name of the identity provider. For example, //iam.googleapis.com/projects//locations/global/workloadIdentityPools//providers/. Required when exchanging an external credential for a Google access token.

Declaration

public virtual string Audience { get; set; }
Property Value
Type Description
string

ETag

The ETag of the item.

Declaration
public virtual string ETag { get; set; }
Property Value
Type Description
string

GrantType

Required. The grant type. Must be urn:ietf:params:oauth:grant-type:token-exchange, which indicates a token exchange.

Declaration
[JsonProperty("grantType")]
public virtual string GrantType { get; set; }
Property Value
Type Description
string

Options

A set of features that Security Token Service supports, in addition to the standard OAuth 2.0 token exchange, formatted as a serialized JSON object of Options. The size of the parameter value must not exceed 4096 characters.

Declaration
[JsonProperty("options")]
public virtual string Options { get; set; }
Property Value
Type Description
string

RequestedTokenType

Required. The type of security token. Must be urn:ietf:params:oauth:token-type:access_token, which indicates an OAuth 2.0 access token.

Declaration
[JsonProperty("requestedTokenType")]
public virtual string RequestedTokenType { get; set; }
Property Value
Type Description
string

Scope

The OAuth 2.0 scopes to include on the resulting access token, formatted as a list of space-delimited, case-sensitive strings. Required when exchanging an external credential for a Google access token.

Declaration
[JsonProperty("scope")]
public virtual string Scope { get; set; }
Property Value
Type Description
string

SubjectToken

Required. The input token. This token is either an external credential issued by a workload identity pool provider, or a short-lived access token issued by Google. If the token is an OIDC JWT, it must use the JWT format defined in RFC 7523, and the subject_token_type must be either urn:ietf:params:oauth:token-type:jwt or urn:ietf:params:oauth:token-type:id_token. The following headers are required: - kid: The identifier of the signing key securing the JWT. - alg: The cryptographic algorithm securing the JWT. Must be RS256 or ES256. The following payload fields are required. For more information, see RFC 7523, Section 3: - iss: The issuer of the token. The issuer must provide a discovery document at the URL /.well-known/openid-configuration, where `` is the value of this field. The document must be formatted according to section 4.2 of the OIDC 1.0 Discovery specification. - iat: The issue time, in seconds, since the Unix epoch. Must be in the past. - exp: The expiration time, in seconds, since the Unix epoch. Must be less than 48 hours after iat. Shorter expiration times are more secure. If possible, we recommend setting an expiration time less than 6 hours. - sub: The identity asserted in the JWT. - aud: For workload identity pools, this must be a value specified in the allowed audiences for the workload identity pool provider, or one of the audiences allowed by default if no audiences were specified. See https://cloud.google.com/iam/docs/reference/rest/v1/projects.locations.workloadIdentityPools.providers#oidc Example header:

{ "alg": "RS256", "kid": "us-east-11" }

Example payload:

{ "iss":
"https://accounts.google.com", "iat": 1517963104, "exp": 1517966704, "aud":
"//iam.googleapis.com/projects/1234567890123/locations/global/workloadIdentityPools/my-pool/providers/my-provider",
"sub": "113475438248934895348", "my_claims": { "additional_claim": "value" } }

If subject_token is for AWS, it must be a serialized GetCallerIdentity token. This token contains the same information as a request to the AWS GetCallerIdentity() method, as well as the AWS signature for the request information. Use Signature Version 4. Format the request as URL-encoded JSON, and set the subject_token_type parameter to urn:ietf:params:aws:token-type:aws4_request. The following parameters are required: - url: The URL of the AWS STS endpoint for GetCallerIdentity(), such as https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15. Regional endpoints are also supported. - method: The HTTP request method: POST. - headers: The HTTP request headers, which must include: - Authorization: The request signature. - x-amz-date: The time you will send the request, formatted as an ISO8601 Basic string. This value is typically set to the current time and is used to help prevent replay attacks. - host: The hostname of the url field; for example, sts.amazonaws.com. - x-goog-cloud-target-resource: The full, canonical resource name of the workload identity pool provider, with or without an https: prefix. To help ensure data integrity, we recommend including this header in the SignedHeaders field of the signed request. For example: //iam.googleapis.com/projects//locations/global/workloadIdentityPools//providers/ https://iam.googleapis.com/projects//locations/global/workloadIdentityPools//providers/ If you are using temporary security credentials provided by AWS, you must also include the header x-amz-security-token, with the value set to the session token. The following example shows a GetCallerIdentity token:

{
"headers": [ {"key": "x-amz-date", "value": "20200815T015049Z"}, {"key": "Authorization", "value":
"AWS4-HMAC-SHA256+Credential=$credential,+SignedHeaders=host;x-amz-date;x-goog-cloud-target-resource,+Signature=$signature"},
{"key": "x-goog-cloud-target-resource", "value":
"//iam.googleapis.com/projects//locations/global/workloadIdentityPools//providers/"}, {"key": "host",
"value": "sts.amazonaws.com"} . ], "method": "POST", "url":
"https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15" }

You can also use a Google-issued OAuth 2.0 access token with this field to obtain an access token with new security attributes applied, such as a Credential Access Boundary. In this case, set subject_token_type to urn:ietf:params:oauth:token-type:access_token. If an access token already contains security attributes, you cannot apply additional security attributes.

Required. An identifier that indicates the type of the security token in the subject_token parameter. Supported values are urn:ietf:params:oauth:token-type:jwt, urn:ietf:params:oauth:token-type:id_token, urn:ietf:params:aws:token-type:aws4_request, and urn:ietf:params:oauth:token-type:access_token.
