// Imports or reimports key material into an existing KMS key that was created
// without key material. ImportKeyMaterial also sets the expiration model and
// expiration date of the imported key material. By default, KMS keys are created
// with key material that KMS generates. This operation supports Importing key
// material (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html)
// , an advanced feature that lets you generate and import the cryptographic key
// material for a KMS key. For more information about importing key material into
// KMS, see Importing key material (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html)
// in the Key Management Service Developer Guide. After you successfully import key
// material into a KMS key, you can reimport the same key material (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html#reimport-key-material)
// into that KMS key, but you cannot import different key material. You might
// reimport key material to replace key material that expired or key material that
// you deleted. You might also reimport key material to change the expiration model
// or expiration date of the key material. Before reimporting key material, if
// necessary, call DeleteImportedKeyMaterial to delete the current imported key
// material. Each time you import key material into KMS, you can determine whether
// ( ExpirationModel ) and when ( ValidTo ) the key material expires. To change the
// expiration of your key material, you must import it again, either by calling
// ImportKeyMaterial or using the import features of the KMS console. Before
// calling ImportKeyMaterial :
//   - Create or identify a KMS key with no key material. The KMS key must have an
//     Origin value of EXTERNAL , which indicates that the KMS key is designed for
//     imported key material. To create an new KMS key for imported key material, call
//     the CreateKey operation with an Origin value of EXTERNAL . You can create a
//     symmetric encryption KMS key, HMAC KMS key, asymmetric encryption KMS key, or
//     asymmetric signing KMS key. You can also import key material into a
//     multi-Region key of any supported type. However, you can't import key material
//     into a KMS key in a custom key store .
//   - Use the DescribeKey operation to verify that the KeyState of the KMS key is
//     PendingImport , which indicates that the KMS key has no key material. If you
//     are reimporting the same key material into an existing KMS key, you might need
//     to call the DeleteImportedKeyMaterial to delete its existing key material.
//   - Call the GetParametersForImport operation to get a public key and import
//     token set for importing key material.
//   - Use the public key in the GetParametersForImport response to encrypt your
//     key material.
//
// Then, in an ImportKeyMaterial request, you submit your encrypted key material
// and import token. When calling this operation, you must specify the following
// values:
//   - The key ID or key ARN of the KMS key to associate with the imported key
//     material. Its Origin must be EXTERNAL and its KeyState must be PendingImport .
//     You cannot perform this operation on a KMS key in a custom key store , or on a
//     KMS key in a different Amazon Web Services account. To get the Origin and
//     KeyState of a KMS key, call DescribeKey .
//   - The encrypted key material.
//   - 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 ). For help with this choice, see Setting an expiration time (https://docs.aws.amazon.com/en_us/kms/latest/developerguide/importing-keys.html#importing-keys-expiration)
//     in the Key Management Service Developer Guide. If you set an expiration date,
//     KMS deletes the key material from the KMS key on the specified date, making the
//     KMS key unusable. To use the KMS key in cryptographic operations again, you must
//     reimport the same key material. However, you can delete and reimport the key
//     material at any time, including before the key material expires. Each time you
//     reimport, you can eliminate or reset the expiration time.
//
// When this operation is successful, the key state of the KMS key changes from
// PendingImport to Enabled , and you can use the KMS key in cryptographic
// operations. 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 (https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html#importing-keys-overview)
// 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 (https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html) 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.
// Required permissions: kms:ImportKeyMaterial (https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html)
