Deletes the specified grant. You revoke a grant to terminate the permissions that the grant allows. For more information, see Retiring and revoking grants in the Key Management Service Developer Guide.

When you create, retire, or revoke a grant, there might be a brief delay, usually less than five minutes, until the grant is available throughout KMS. This state is known as eventual consistency. For details, see Eventual consistency in the Key Management Service Developer Guide.

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.

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:RevokeGrant (key policy).

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to RevokeGrantAsync.

Namespace: Amazon.KeyManagementService
Assembly: AWSSDK.KeyManagementService.dll
Version: 3.x.y.z

Syntax

C#
public virtual RevokeGrantResponse RevokeGrant(
         String grantId,
         String keyId
)
Parameters
grantId
Type: System.String

Identifies the grant to revoke. To get the grant ID, use CreateGrant, ListGrants, or ListRetirableGrants.

keyId
Type: System.String

A unique identifier for the KMS key associated with the grant. To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. 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 ListKeys or DescribeKey.

Return Value
The response from the RevokeGrant service method, as returned by KeyManagementService.

Exceptions

ExceptionCondition
DependencyTimeoutException The system timed out while trying to fulfill the request. You can retry the request.
InvalidArnException The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.
InvalidGrantIdException The request was rejected because the specified GrantId is not valid.
KMSInternalException The request was rejected because an internal exception occurred. The request can be retried.
KMSInvalidStateException The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide. For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception.
NotFoundException The request was rejected because the specified entity or resource could not be found.
