<p>Returns the items you need to import key material into a symmetric encryption KMS key. For more information about importing key material into KMS, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/importing-keys.html">Importing key material</a> in the <i>Key Management Service Developer Guide</i>.</p> <p>This operation returns a public key and an import token. Use the public key to encrypt the symmetric key material. Store the import token to send with a subsequent <a>ImportKeyMaterial</a> request.</p> <p>You must specify the key ID of the symmetric encryption KMS key into which you will import key material. The KMS key <code>Origin</code> must be <code>EXTERNAL</code>. You must also specify the wrapping algorithm and type of wrapping key (public key) that you will use to encrypt the 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.</p> <p>To import key material, you must use the public key and import token from the same response. These items are valid for 24 hours. The expiration date and time appear in the <code>GetParametersForImport</code> response. You cannot use an expired token in an <a>ImportKeyMaterial</a> request. If your key and token expire, send another <code>GetParametersForImport</code> request.</p> <p>The KMS key that you use for this operation must be in a compatible key state. For details, see <a href="https://docs.aws.amazon.com/kms/latest/developerguide/key-state.html">Key states of KMS keys</a> in the <i>Key Management Service Developer Guide</i>.</p> <p> <b>Cross-account use</b>: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.</p> <p> <b>Required permissions</b>: <a href="https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html">kms:GetParametersForImport</a> (key policy)</p> <p> <b>Related operations:</b> </p> <ul> <li> <p> <a>ImportKeyMaterial</a> </p> </li> <li> <p> <a>DeleteImportedKeyMaterial</a> </p> </li> </ul>
