# AWS CloudHSM Key Management Utility (KMU)
<a name="key_mgmt_util"></a>

The key management utility (KMU) is a command line tool for AWS CloudHSM that helps crypto users (CU) manage keys on the hardware security modules (HSM). KMU includes multiple commands that generate, delete, import, and export keys, get and set attributes, find keys, and perform cryptographic operations. 

KMU and CMU are part of [the Client SDK 3 suite](choose-client-sdk.md).

For a quick start, see [Getting started with AWS CloudHSM key\$1mgmt\$1util](key_mgmt_util-getting-started.md). For detailed information about the commands, see [Reference for AWS CloudHSM Key Management Utility commands](key_mgmt_util-reference.md). For help interpreting the key attributes, see the [AWS CloudHSM key attribute reference for KMU](key-attribute-table.md). 

To use key\$1mgmt\$1util if you are using Linux, connect to your client instance and then see [Install and configure the AWS CloudHSM client for KMU (Linux)](kmu-install-and-configure-client-linux.md). If you are using Windows, see [Install and configure the AWS CloudHSM client for KMU (Windows)](kmu-install-and-configure-client-win.md).
