# Load a keystore

> Use the Keystore Manager to load an existing keystore.

This page explains how to load an existing keystore and select a key from it to use as the project key.

This is relevant if you want to publish your application, because you must provide a key from a keystore when you sign the application.

To load an existing keystore:

1. Open [Android Publishing Settings](/engine/6000.7/manual/platform-specific/android/getting-started/class-player-settings.md#Publishing).
2. Under the **Project Keystore** heading, enable **Custom Keystore**.
3. Click the drop-down below **Custom Keystore**.
4. Select **Browse** to load a keystore from your file system, or select a keystore from below the partition in the UI. The keystores below the partition are those stored in the keystores dedicated location. For more information, see [Choose the keystore location](/engine/6000.7/manual/platform-specific/android/getting-started/keystore/create.md#choose-the-keystore-location).
5. Enter the password for the keystore in the **Keystore password** property field. If the password is correct, Unity loads the keystore.

After you load a keystore into your project, select a key from the keystore to use as the key alias. To do this:

1. Use the dropdown list in **Key alias** to select the key you want to use.
2. In the **Key password** property field, enter the password for the key.
