KMS / Client / revoke_grant

revoke_grant#

KMS.Client.revoke_grant(**kwargs)#

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).

Related operations:

  • CreateGrant

  • ListGrants

  • ListRetirableGrants

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

    GrantId='string',
    DryRun=True|False
)
Parameters:

  • KeyId (string) –

    [REQUIRED]

    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.

  • GrantId (string) –

    [REQUIRED]

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

  • DryRun (boolean) –

    Checks if your request will succeed. DryRun is an optional parameter.

Examples

The following example revokes a grant.

response = client.revoke_grant(
    # The identifier of the grant to revoke.
    GrantId='0c237476b39f8bc44e45212e08498fbe3151305030726c0590dd8d3e9f3d6a60',
    # The identifier of the KMS key associated with the grant. You can use the key ID or the Amazon Resource Name (ARN) of the KMS key.
    KeyId='1234abcd-12ab-34cd-56ef-1234567890ab',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
