Synopsis

  update-key-description
--key-id <value>
--description <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--key-id (string)

Updates the description of the specified KMS key.

Specify the key ID or key ARN of the KMS key.

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 .

--description (string)

New description for the KMS key.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To add or change a description to a customer managed KMS key

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

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

• The --description parameter specifies the new description. The value of this parameter replaces the current description of the KMS key, 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 KMS key, use the describe-key command.

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

Example 2: To delete the description of a customer managed KMS key

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

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

• 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 KMS key, use the the describe-key command.
