import-key-material

Description

Imports key material into an existing symmetric encryption KMS key that was created without key material. After you successfully import key material into a KMS key, you can reimport the same key material into that KMS key, but you cannot import different key material.

You cannot perform this operation on an asymmetric KMS key, an HMAC KMS key, or on any KMS key in a different Amazon Web Services account. For more information about creating KMS keys with no key material and then importing key material, see Importing Key Material in the Key Management Service Developer Guide .

Before using this operation, call GetParametersForImport . Its response includes a public key and an import token. Use the public key to encrypt the key material. Then, submit the import token from the same GetParametersForImport response.

When calling this operation, you must specify the following values:

  • The key ID or key ARN of a KMS key with no key material. Its Origin must be EXTERNAL . To create a KMS key with no key material, call CreateKey and set the value of its Origin parameter to EXTERNAL . To get the Origin of a KMS key, call DescribeKey .)

  • The encrypted key material. To get the public key to encrypt the key material, call GetParametersForImport .

  • The import token that GetParametersForImport returned. You must use a public key and token from the same GetParametersForImport response.

  • Whether the key material expires (ExpirationModel ) and, if so, when (ValidTo ). If you set an expiration date, on the specified date, KMS deletes the key material from the KMS key, making the KMS key unusable. To use the KMS key in cryptographic operations again, you must reimport the same key material. The only way to change the expiration model or expiration date is by reimporting the same key material and specifying a new expiration date.

When this operation is successful, the key state of the KMS key changes from PendingImport to Enabled , and you can use the KMS key.

If this operation fails, use the exception to help determine the problem. If the error is related to the key material, the import token, or wrapping key, use GetParametersForImport to get a new public key and import token for the KMS key and repeat the import procedure. For help, see How To Import Key Material in the Key Management Service Developer Guide .

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 a KMS key in a different Amazon Web Services account.

Options

--key-id (string)

The identifier of the symmetric encryption KMS key that receives the imported key material. This must be the same KMS key specified in the KeyID parameter of the corresponding GetParametersForImport request. The Origin of the KMS key must be EXTERNAL . You cannot perform this operation on an asymmetric KMS key, an HMAC KMS key, a KMS key in a custom key store, or on a KMS key in a different Amazon Web Services account

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 .

--import-token (blob)

The import token that you received in the response to a previous GetParametersForImport request. It must be from the same response that contained the public key that you used to encrypt the key material.

--encrypted-key-material (blob)

The encrypted key material to import. The key material must be encrypted with the public wrapping key that GetParametersForImport returned, using the wrapping algorithm that you specified in the same GetParametersForImport request.

--valid-to (timestamp)

The date and time when the imported key material expires. This parameter is required when the value of the ExpirationModel parameter is KEY_MATERIAL_EXPIRES . Otherwise it is not valid.

The value of this parameter must be a future date and time. The maximum value is 365 days from the request date.

When the key material expires, KMS deletes the key material from the KMS key. Without its key material, the KMS key is unusable. To use the KMS key in cryptographic operations, you must reimport the same key material.

You cannot change the ExpirationModel or ValidTo values for the current import after the request completes. To change either value, you must delete ( DeleteImportedKeyMaterial ) and reimport the key material.

--expiration-model (string)

Specifies whether the key material expires. The default is KEY_MATERIAL_EXPIRES .

When the value of ExpirationModel is KEY_MATERIAL_EXPIRES , you must specify a value for the ValidTo parameter. When value is KEY_MATERIAL_DOES_NOT_EXPIRE , you must omit the ValidTo parameter.

You cannot change the ExpirationModel or ValidTo values for the current import after the request completes. To change either value, you must delete ( DeleteImportedKeyMaterial ) and reimport the key material.

Possible values:

  • KEY_MATERIAL_EXPIRES

  • KEY_MATERIAL_DOES_NOT_EXPIRE

--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.

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

  • yaml

  • yaml-stream

--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)

Turn on/off color output.

  • on

  • off

  • auto

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input 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 import key material into a KMS key

The following import-key-material example uploads key material into a KMS key that was created with no key material. The key state of the KMS key must be PendingImport.

This command uses key material that you encrypted with the public key that the get-parameters-for-import command returned. It also uses the import token from the same get-parameters-for-import command.

The expiration-model parameter indicates that the key material automatically expires on the date and time specified by the valid-to parameter. When the key material expires, AWS KMS deletes the key material, the key state of the KMS key changes to Pending import and the KMS key becomes unusable. To restore the KMS key, you must reimport the same key material. To use different key material, you must create a new KMS key.

Before running this command, replace the example key ID with a valid key ID or key ARN from your AWS account.

aws kms import-key-material \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --encrypted-key-material fileb://EncryptedKeyMaterial.bin \
    --import-token fileb://ImportToken.bin \
    --expiration-model KEY_MATERIAL_EXPIRES \
    --valid-to 2021-09-21T19:00:00Z

This command produces no output.
