Synopsis

  get-key-policy
--key-id <value>
--policy-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--key-id (string)

Gets the key policy for 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 .

--policy-name (string)

Specifies the name of the key policy. The only valid name is default . To get the names of key policies, use ListKeyPolicies .

--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 .

To copy a key policy from one KMS key to another KMS key

The following get-key-policy example gets the key policy from one KMS key and saves it in a text file. Then, it replaces the policy of a different KMS key using the text file as the policy input.

Because the --policy parameter of put-key-policy requires a string, you must use the --output text option to return the output as a text string instead of JSON.

aws kms get-key-policy \
    --policy-name default \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --query Policy \
    --output text > policy.txt

aws kms put-key-policy \
    --policy-name default \
    --key-id 0987dcba-09fe-87dc-65ba-ab0987654321 \
    --policy file://policy.txt

This command produces no output.

For more information, see PutKeyPolicy in the AWS KMS API Reference.

Output

Policy -> (string)

A key policy document in JSON format.
