+++ title = "Sign a plugin" +++ # 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. ## Sign your plugin using Grafana Toolkit The easiest way to sign your plugin is by using the [Grafana Toolkit](https://www.npmjs.com/package/@grafana/toolkit). You can sign your plugin as a _public_ or a _private_ plugin. In both cases, you need to [create an account on Grafana.com](https://grafana.com/signup) and generate an API key with the `PluginPublisher` role. By creating an account, you can verify that you own the plugin that you want to sign. ### Sign a public plugin Plugins signed under the community or commercial signature level are considered _public plugins_. Public plugins are published on [Grafana Plugin](https://grafana.com/plugins). For more information about installing public plugins, refer to [Install Grafana plugins]({{< relref "../../plugins/installation.md" >}}). 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](#plugin-signature-levels). **Without a plugin signature level, you won't be able to sign your plugin**. 1. 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. ``` export GRAFANA_API_KEY= npx @grafana/toolkit plugin:sign ``` ### Sign a private plugin If you're developing plugins for internal use only and don't want to make it public, you can sign it under a Private [signature level](#plugin-signature-levels). 1. 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 for which the plugin can be used. The URLs need to match the [root_url]({{< relref "../../administration/configuration.md#root_url" >}}) setting. ``` export GRAFANA_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**| |---|---|---| |Private|No;
Free of charge|

You can create and sign a Private Plugin for any technology at no charge.

Private Plugins are for use on your own Grafana. They may not be distributed to the Grafana community, and are not published in the Grafana catalog.

| |Community|No;
Free of charge|

You can create, sign and distribute plugins at no charge, provided that all dependent technologies are open source and not for profit.

Community Plugins are published in the official Grafana catalog, and are available to the Grafana community.

| |Commercial|Yes;
Commercial Plugin Subscription required|

You can create, sign and distribute plugins with dependent technologies that are closed source or commercially backed, by entering into a Commercial Plugin Subscription with Grafana Labs.

Commercial Plugins are published on the official Grafana catalog, and are available to the Grafana community.

| 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 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 { "manifestVersion": "2.0.0", "signatureType": "community", "signedByOrg": "myorgid", "signedByOrgName": "My Org", "plugin": "myorgid-simple-panel", "version": "1.0.0", "time": 1602753404133, "keyId": "7e4d0c6a708866e7", "files": { "LICENSE": "12ab7a0961275f5ce7a428e662279cf49bab887d12b2ff7bfde738346178c28c", "module.js.LICENSE.txt": "0d8f66cd4afb566cb5b7e1540c68f43b939d3eba12ace290f18abc4f4cb53ed0", "module.js.map": "8a4ede5b5847dec1c6c30008d07bef8a049408d2b1e862841e30357f82e0fa19", "plugin.json": "13be5f2fd55bee787c5413b5ba6a1fae2dfe8d2df6c867dadc4657b98f821f90", "README.md": "2d90145b28f22348d4f50a81695e888c68ebd4f8baec731fdf2d79c8b187a27f", "module.js": "b4b6945bbf3332b08e5e1cb214a5b85c82557b292577eb58c8eb1703bc8e4577" } } -----BEGIN PGP SIGNATURE----- Version: OpenPGP.js v4.10.1 Comment: https://openpgpjs.org wqEEARMKAAYFAl+IE3wACgkQfk0ManCIZudpdwIHTCqjVzfm7DechTa7BTbd +dNIQtwh8Tv2Q9HksgN6c6M9nbQTP0xNHwxSxHOI8EL3euz/OagzWoiIWulG 7AQo7FYCCQGucaLPPK3tsWaeFqVKy+JtQhrJJui23DAZLSYQYZlKQ+nFqc9x T6scfmuhWC/TOcm83EVoCzIV3R5dOTKHqkjIUg== =GdNq -----END PGP SIGNATURE----- ``` ## 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).
