// Returns information about all grants in the Amazon Web Services account and
// Region that have the specified retiring principal.
//
// You can specify any principal in your Amazon Web Services account. The grants
// that are returned include grants for KMS keys in your Amazon Web Services
// account and other Amazon Web Services accounts. You might use this operation to
// determine which grants you may retire. To retire a grant, use the RetireGrantoperation.
//
// For detailed information about grants, including grant terminology, see [Grants in KMS] in the
// Key Management Service Developer Guide . For examples of creating grants in
// several programming languages, see [Use CreateGrant with an Amazon Web Services SDK or CLI].
//
// Cross-account use: You must specify a principal in your Amazon Web Services
// account. This operation returns a list of grants where the retiring principal
// specified in the ListRetirableGrants request is the same retiring principal on
// the grant. This can include grants on KMS keys owned by other Amazon Web
// Services accounts, but you do not need kms:ListRetirableGrants permission (or
// any other additional permission) in any Amazon Web Services account other than
// your own.
//
// Required permissions: [kms:ListRetirableGrants] (IAM policy) in your Amazon Web Services account.
//
// KMS authorizes ListRetirableGrants requests by evaluating the caller account's
// kms:ListRetirableGrants permissions. The authorized resource in
// ListRetirableGrants calls is the retiring principal specified in the request.
// KMS does not evaluate the caller's permissions to verify their access to any KMS
// keys or grants that might be returned by the ListRetirableGrants call.
