[ aws . kms ]

put-key-policy

Description

Attaches a key policy to the specified customer master key (CMK). You cannot perform this operation on a CMK in a different AWS account.

For more information about key policies, see Key Policies in the AWS Key Management Service Developer Guide .

See also: AWS API Documentation

Synopsis

  put-key-policy
--key-id <value>
--policy-name <value>
--policy <value>
[--bypass-policy-lockout-safety-check | --no-bypass-policy-lockout-safety-check]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--key-id (string)

A unique identifier for the customer master key (CMK).

Specify the key ID or the Amazon Resource Name (ARN) of the CMK.

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 CMK, use list-keys or describe-key .

--policy-name (string)

The name of the key policy. The only valid value is default .

--policy (string)

The key policy to attach to the CMK.

If you do not set BypassPolicyLockoutSafetyCheck to true, the policy must meet the following criteria:

  • It must allow the principal that is making the put-key-policy request to make a subsequent put-key-policy request on the CMK. This reduces the likelihood that the CMK becomes unmanageable. For more information, refer to the scenario in the Default Key Policy section in the AWS Key Management Service Developer Guide .
  • The principals that are specified in the key policy must exist and be visible to AWS KMS. When you create a new AWS principal (for example, an IAM user or role), you might need to enforce a delay before specifying the new principal in a key policy because the new principal might not immediately be visible to AWS KMS. For more information, see Changes that I make are not always immediately visible in the IAM User Guide .

The policy size limit is 32 kilobytes (32768 bytes).

--bypass-policy-lockout-safety-check | --no-bypass-policy-lockout-safety-check (boolean)

A flag to indicate whether to bypass the key policy lockout safety check.

Warning

Setting this value to true increases the likelihood that the CMK becomes unmanageable. Do not set this value to true indiscriminately.

For more information, refer to the scenario in the Default Key Policy section in the AWS Key Management Service Developer Guide .

Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent put-key-policy request on the CMK.

The default value is false.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

None
