create-alias

Description

Creates a friendly name for a KMS key.

Note

Adding, deleting, or updating an alias can allow or deny permission to the KMS key. For details, see ABAC for KMS in the Key Management Service Developer Guide .

You can use an alias to identify a KMS key in the KMS console, in the DescribeKey operation and in cryptographic operations , such as Encrypt and GenerateDataKey . You can also change the KMS key that's associated with the alias ( UpdateAlias ) or delete the alias ( DeleteAlias ) at any time. These operations don't affect the underlying KMS key.

You can associate the alias with any customer managed key in the same Amazon Web Services Region. Each alias is associated with only one KMS key at a time, but a KMS key can have multiple aliases. A valid KMS key is required. You can't create an alias without a KMS key.

The alias must be unique in the account and Region, but you can have aliases with the same name in different Regions. For detailed information about aliases, see Using aliases in the Key Management Service Developer Guide .

This operation does not return a response. To get the alias that you created, use the ListAliases operation.

The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the Key Management Service Developer Guide .

Cross-account use : No. You cannot perform this operation on an alias in a different Amazon Web Services account.

Required permissions

For details, see Controlling access to aliases in the Key Management Service Developer Guide .

  • ListAliases

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

Options

--alias-name (string)

Specifies the alias name. This value must begin with alias/ followed by a name, such as alias/ExampleAlias .

Warning

Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

The AliasName value must be string of 1-256 characters. It can contain only alphanumeric characters, forward slashes (/), underscores (_), and dashes (-). The alias name cannot begin with alias/aws/ . The alias/aws/ prefix is reserved for Amazon Web Services managed keys .

--target-key-id (string)

Associates the alias with the specified customer managed key . The KMS key must be in the same Amazon Web Services Region.

A valid key ID is required. If you supply a null or empty string value, this operation returns an error.

For help finding the key ID and ARN, see Finding the Key ID and ARN in the * Key Management Service Developer Guide * .

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 .

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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 create an alias for a KMS key

The following create-alias command creates an alias named example-alias for the KMS key identified by key ID 1234abcd-12ab-34cd-56ef-1234567890ab.

Alias names must begin with alias/. Do not use alias names that begin with alias/aws; these are reserved for use by AWS.

aws kms create-alias \
    --alias-name alias/example-alias \
    --target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab

This command doesn't return any output. To see the new alias, use the list-aliases command.

For more information, see Using aliases in the AWS Key Management Service Developer Guide.
