Synopsis

  update-key-description
--key-id <value>
--description <value>
[--cli-input-json | --cli-input-yaml]
[--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 ListKeys or DescribeKey .

--description (string)

New description for the CMK.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

Example 1: To delete the description of a customer managed CMK

The following update-key-description example deletes the description to a customer managed CMK.

• The --key-id parameter identifies the CMK in the command. This example uses a key ID value, but you can use either the key ID or the key ARN of the CMK.

• The --description parameter with an empty string value (‘’) deletes the existing description.

  aws kms update-key-description \
      --key-id 0987dcba-09fe-87dc-65ba-ab0987654321 \
      --description ''
  

This command produces no output. To view the description of a CMK, use the the describe-key command.

For more information, see UpdateKeyDescription in the AWS Key Management Service API Reference.

Example 2: To add or change a description to a customer managed CMK

The following update-key-description example adds a description to a customer managed CMK. You can use the same command to change an existing description.

• The --key-id parameter identifies the CMK in the command. This example uses a key ARN value, but you can use either the key ID or the key ARN of the CMK.

• The --description parameter specifies the new description. The value of this parameter replaces the current description of the CMK, if any.

  aws kms update-key-description \
      --key-id arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab \
      --description "IT Department test key"
  

This command produces no output. To view the description of a CMK, use the describe-key command.
