List Grants

kms_list_grants R Documentation

Gets a list of all grants for the specified KMS key

Description

Gets a list of all grants for the specified KMS key.

You must specify the KMS key in all requests. You can filter the grant list by grant ID or grantee principal.

For detailed information about grants, including grant terminology, see Grants in KMS in the Key Management Service Developer Guide . For examples of working with grants in several programming languages, see Programming grants.

The GranteePrincipal field in the list_grants response usually contains the user or role designated as the grantee principal in the grant. However, when the grantee principal in the grant is an Amazon Web Services service, the GranteePrincipal field contains the service principal, which might represent several different grantee principals.

Cross-account use: Yes. To perform this operation on a KMS key in a different Amazon Web Services account, specify the key ARN in the value of the KeyId parameter.

Required permissions: kms:ListGrants (key policy)

Related operations:

  • create_grant

  • list_retirable_grants

  • retire_grant

  • revoke_grant

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.

Usage

kms_list_grants(Limit, Marker, KeyId, GrantId, GranteePrincipal)

Arguments

Limit

Use this parameter to specify the maximum number of items to return. When this value is present, KMS does not return more than the specified number of items, but it might return fewer.

This value is optional. If you include a value, it must be between 1 and 100, inclusive. If you do not include a value, it defaults to 50.

Marker

Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.

KeyId

[required] Returns only grants for the specified KMS key. This parameter is required.

Specify the key ID or key ARN of the KMS key. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN.

For example:

  • Key ID: ⁠1234abcd-12ab-34cd-56ef-1234567890ab⁠

  • Key ARN: ⁠arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab⁠

To get the key ID and key ARN for a KMS key, use list_keys or describe_key.

GrantId

Returns only the grant with the specified grant ID. The grant ID uniquely identifies the grant.

GranteePrincipal

Returns only grants where the specified principal is the grantee principal for the grant.

Value

A list with the following syntax: 

list(
  Grants = list(
    list(
      KeyId = "string",
      GrantId = "string",
      Name = "string",
      CreationDate = as.POSIXct(
        "2015-01-01"
      ),
      GranteePrincipal = "string",
      RetiringPrincipal = "string",
      IssuingAccount = "string",

      ),
      Constraints = list(
        EncryptionContextSubset = list(
          "string"
        ),
        EncryptionContextEquals = list(
          "string"
        )
      )
    )
  ),
  NextMarker = "string",
  Truncated = TRUE|FALSE
)

Request syntax

svc$list_grants(
  Limit = 123,
  Marker = "string",
  KeyId = "string",
  GrantId = "string",
  GranteePrincipal = "string"
)
