Description

Imports key material into an existing symmetric AWS KMS customer master key (CMK) that was created without key material. After you successfully import key material into a CMK, you can reimport the same key material into that CMK, but you cannot import different key material.

Usage

kms_import_key_material(KeyId, ImportToken, EncryptedKeyMaterial,
  ValidTo, ExpirationModel)

Arguments

KeyId

[required] The identifier of the symmetric CMK that receives the imported key material. The CMK\'s Origin must be EXTERNAL. This must be the same CMK specified in the KeyID parameter of the corresponding GetParametersForImport request.

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.

ImportToken

[required] 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.

EncryptedKeyMaterial

[required] 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.

ValidTo

The time at which the imported key material expires. When the key material expires, AWS KMS deletes the key material and the CMK becomes unusable. You must omit this parameter when the ExpirationModel parameter is set to KEY_MATERIAL_DOES_NOT_EXPIRE. Otherwise it is required.

ExpirationModel

Specifies whether the key material expires. The default is KEY_MATERIAL_EXPIRES, in which case you must include the ValidTo parameter. When this parameter is set to KEY_MATERIAL_DOES_NOT_EXPIRE, you must omit the ValidTo parameter.

Details

You cannot perform this operation on an asymmetric CMK or on any CMK in a different AWS account. For more information about creating CMKs with no key material and then importing key material, see Importing Key Material in the AWS 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:

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

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 CMK and repeat the import procedure. For help, see How To Import Key Material in the AWS Key Management Service Developer Guide.

The CMK that you use for this operation must be in a compatible key state. For details, see How Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer Guide.
