# Sign a plugin

Signing a plugin allows Grafana to verify the authenticity of the plugin with [signature verification]({{< relref "../../plugins/plugin-signatures.md" >}}). This gives users a way to make sure plugins haven't been tampered with. All Grafana Labs-authored backend plugins, including Enterprise plugins, are signed.

> **Important:** Future versions of Grafana will require all plugins to be signed.

Before you can sign your plugin, you need to decide whether you want to sign it as a _public_ or a _private_ plugin.

If you want to make your plugin publicly available outside of your organization, you need to sign your plugin under a _community_ or _commercial_ [signature level](#plugin-signature-levels). Public plugins are available from [grafana.com/plugins](https://grafana.com/plugins) and can be installed by anyone.

For more information on how to install public plugin, refer to [Install Grafana plugins]({{< relref "../../plugins/installation.md" >}}).

If you intend to only use the plugin within your organization, you can to sign it under a _private_ [signature level](#plugin-signature-levels).

## Generate an API key

To verify ownership of your plugin, you need to generate an API key that you'll use every time you need to sign a new version of your plugin.

1. [Create a Grafana Cloud account](https://grafana.com/signup).

1. Make sure that the first part of the plugin ID matches the slug of your Grafana Cloud account.

   You can find the plugin ID in the `plugin.json` file inside your plugin directory. For example, if your account slug is `acmecorp`, you need to prefix the plugin ID with `acmecorp-`.

1. [Create a Grafana Cloud API key](https://grafana.com/docs/grafana-cloud/cloud-portal/create-api-key/) with the **PluginPublisher** role.

## Sign a public plugin

Public plugins need to be reviewed by the Grafana team before you can sign them.

1. Submit your plugin for review by creating a pull request in the [grafana-plugin-repository](https://github.com/grafana/grafana-plugin-repository).
1. When your plugin is approved, you're granted a plugin signature level. **Without a plugin signature level, you won't be able to sign your plugin**.
1. In your plugin directory, sign the plugin with the API key you just created. Grafana Toolkit creates a [MANIFEST.txt](#plugin-manifest) file in the `dist` directory of your plugin.

   ```bash
   export GRAFANA_API_KEY=<YOUR_API_KEY>
   npx @grafana/toolkit plugin:sign
   ```

## Sign a private plugin

1. In your plugin directory, sign the plugin with the API key you just created. Grafana Toolkit creates a [MANIFEST.txt](#plugin-manifest) file in the `dist` directory of your plugin.

   The `rootUrls` flag accepts a comma-separated list of URLs to the Grafana instances where you intend to install the plugin.

   ```bash
   export GRAFANA_API_KEY=<YOUR_API_KEY>
   npx @grafana/toolkit plugin:sign --rootUrls https://example.com/grafana
   ```

## Plugin signature levels

To sign a plugin, you need to decide the _signature level_ you want to sign it under. The signature level of your plugin determines how you can distribute it.

You can sign your plugin under three different _signature levels_.

| **Plugin Level** | **Paid Subscription Required?**                 | **Description**                                                                                                                                                                                                                                                                                                        |

For instructions on how to sign a plugin under the Community and Commercial signature level, refer to [Sign a public plugin](#sign-a-public-plugin).

For instructions on how to sign a plugin under the Private signature level, refer to [Sign a private plugin](#sign-a-private-plugin).

## Plugin manifest

For Grafana to verify the digital signature of a plugin, the plugin must include a signed manifest file, _MANIFEST.txt_. The signed manifest file contains two sections:

- **Signed message -** The signed message contains plugin metadata and plugin files with their respective checksums (SHA256).
- **Digital signature -**  The digital signature is created by encrypting the signed message using a private key. Grafana has a public key built-in that can be used to verify that the digital signature have been encrypted using expected private key.

**Example manifest file:**

```txt

## Troubleshooting issues while signing your plugin

### Why am I getting a "Modified signature" in Grafana?

Due to an issue when signing the plugin on Windows, grafana-toolkit generates an invalid MANIFEST.txt. You can fix this by replacing all double backslashes, `\\`, with a forward slash, `/` in the MANIFEST.txt file. You need to do this every time you sign your plugin.

### Error signing manifest: Field is required: rootUrls

If you're trying to sign a **public** plugin, this means that your plugin doesn't have a plugin signature level assigned to it yet. A Grafana team member will assign a signature level to your plugin once it has been reviewed and approved. For more information, refer to [Sign a public plugin](#sign-a-public-plugin).

If you're trying to sign a **private** plugin, this means that you need to add a `rootUrls` flag to the `plugin:sign` command. The `rootUrls` must match the [root_url]({{< relref "../../administration/configuration.md#root_url" >}}) configuration. For more information, refer to [Sign a private plugin](#sign-a-private-plugin).

If you still get this error, make sure that the API key was generated by a Grafana Cloud account that matches the first part of the plugin ID.
