# electron-osx-sign [![npm][npm_img]][npm_url] [![Build Status][circleci_img]][circleci_url]

Codesign Electron macOS apps

## About

[`electron-osx-sign`][electron-osx-sign] minimizes the extra work needed to eventually prepare your apps for shipping, providing the most basic tools and assets. Note that the bare necessities here are sufficient for enabling app sandbox, yet other configurations for network access etc. require additional work.

Check out [`electron-osx-sign` guide](https://mintkit.net/electron-userland/electron-osx-sign/guide/) for suggestions on setting up your environment and workflow for distribution or development.

Please visit our [wiki](https://github.com/electron-userland/electron-osx-sign/wiki) for walk-throughs, notes and [frequently asked questions](https://github.com/electron-userland/electron-osx-sign/wiki/FAQ) from past projects shipped with [`electron-packager`][electron-packager] and [`electron-osx-sign`][electron-osx-sign].

*NB: Since [`electron-osx-sign`][electron-osx-sign] injects the entry `com.apple.security.application-groups` into the entitlements file as part of the pre-signing process, this would reportedly limit app transfer on iTunes Connect (see [#150](https://github.com/electron-userland/electron-osx-sign/issues/150)). However, opting out entitlements automation `opts['pre-auto-entitlements'] === false` may result in worse graphics performance.*

*The signing procedure implemented in this package is based on what described in [Mac App Store Submission Guide](https://github.com/atom/electron/blob/master/docs/tutorial/mac-app-store-submission-guide.md).*

### [Electron]

It is worth noting as well that starting from [Electron] v1.1.1, a new mechanism was introduced to allow IPC in App Sandbox (see [electron#5601](https://github.com/electron/electron/pull/5601)); wish to have full support of legacy Electron versions, please utilize `opts.version`, which option brings less hassle with making default settings among Electron builds.

We are trying to keep updated to the latest [Electron] specs; please [file us an issue](https://github.com/electron-userland/electron-osx-sign/issues/new) if having any suggestions or experiencing difficulties code signing your products.

### An [OPEN Open Source Project](http://openopensource.org/)

Individuals making significant and valuable contributions are given commit-access to the project to contribute as they see fit. This project is more like an open wiki than a standard guarded open source project.

### Collaborators

Thanks to [seanchas116](https://github.com/seanchas116), [jasonhinkle](https://github.com/jasonhinkle), and [develar](https://github.com/develar) for improving the usability of this project implementation.

## Installation

```sh
# For use in npm scripts
npm install --save electron-osx-sign
```

```sh
# For use from CLI
npm install -g electron-osx-sign
```

*Note: `electron-osx-sign` is a dependency of `electron-packager` as of 6.0.0 for signing apps on macOS. However, feel free to install this package globally for more customization beyond specifying identity and entitlements.*

## Usage

### electron-osx-sign

#### From the Command Line

```sh
electron-osx-sign app [embedded-binary ...] [options ...]
```

##### Examples

Since `electron-osx-sign` adds the entry `com.apple.developer.team-identifier` to a temporary copy of the specified entitlements file (with the default option `--pre-auto-entitlements`) distribution builds can no longer be run directly. To run the app codesigned for distribution locally after codesigning, you may manually add `ElectronTeamID` in your `Info.plist` and `com.apple.security.application-groups` in the entitlements file, and provide the flag `--no-pre-auto-entitlements` for `electron-osx-sign` to avoid this extra bit. Note that "certain features are only allowed across apps whose team-identifier value match" ([Technical Note TN2415](https://developer.apple.com/library/content/technotes/tn2415/_index.html#//apple_ref/doc/uid/DTS40016427-CH1-ENTITLEMENTSLIST)).

The examples below assume that `--pre-auto-entitlements` is enabled.

- To sign a distribution version by default:
  ```sh
  electron-osx-sign path/to/my.app
  ```
  For distribution in the Mac App Store: Have the provisioning profile for distribution placed in the current working directory and the signing identity installed in the default keychain. *The app is not expected to run after codesigning since there is no provisioned device, and it is intended only for submission to iTunes Connect.*
  For distribution outside the Mac App Store: Have the signing identity for distribution installed in the default keychain and optionally place the provisioning profile in the current working directory. By default App Sandbox is not enabled. *The app should run on all devices.*

- To sign development version:
  ```sh
  electron-osx-sign path/to/my.app --type=development
  ```
  For testing Mac App Store builds: Have the provisioning profile for development placed in the current working directory and the signing identity installed in the default keychain. *The app will only run on provisioned devices.*
  For testing apps for distribution outside the Mac App Store, have the signing identity for development installed in the default keychain and optionally the provisioning profile placed in the current working directory. *The app will only run on provisioned devices.* However, you may prefer to just go with signing a distribution version because the app is expected to launch properly after codesigned.

- It is recommended to place the provisioning profile(s) under the working directory for `electron-osx-sign` to pick up automatically; however, to specify provisioning profile to be embedded explicitly:
  ```sh
  electron-osx-sign path/to/my.app --provisioning-profile=path/to/my.provisionprofile
  ```

- To specify the entitlements file:
  ```sh
  electron-osx-sign path/to/my.app --entitlements=path/to/my.entitlements
  ```

- It is recommended to make use of `--version` while signing legacy versions of Electron:
  ```sh
  electron-osx-sign path/to/my.app --version=0.34.0
  ```

Run `electron-osx-sign --help` or see [electron-osx-sign-usage.txt](https://github.com/electron-userland/electron-osx-sign/blob/master/bin/electron-osx-sign-usage.txt) for CLI-specific options.

#### From the API

```javascript
var sign = require('electron-osx-sign')
sign(opts[, function done (err) {}])
```

Example:

```javascript
var sign = require('electron-osx-sign')
sign({
  app: 'path/to/my.app'
}, function done (err) {
  if (err) {
    // Handle the error
    return;
  }
  // Application signed
})
```

From release v0.4.0-beta, [Bluebird] promises are introduced for better async method calls; the following is also available for use.

```javascript
var signAsync = require('electron-osx-sign').signAsync
signAsync(opts)
  [.then(function () {})]
  [.catch(function (err) {})]
```

Example:

```javascript
var signAsync = require('electron-osx-sign').signAsync
signAsync({
  app: 'path/to/my.app'
})
  .then(function () {
    // Application signed
  })
  .catch(function (err) {
    // Handle the error
  })
```

Default to the same entitlements file used for signing the app bundle.

`entitlementsForFile` - *Function*

Function that receives the path to a file and the current codesign arguments as parameters.  If you wish to override the entitlements used for this file path this function should return the absolute path to a different entitlements file.

**Note:** Only available via the JS API

`gatekeeper-assess` - *Boolean*

Flag to enable/disable Gatekeeper assessment after signing the app. Disabling it is useful for signing with self-signed certificates.
Gatekeeper assessment is enabled by default on `darwin` platform.
Default to `true`.

`hardenedRuntime` or `hardened-runtime` - *Boolean*

Flag to enable the Mojave hardened runtime when signing the app.  Disabled by default, requires Xcode >= 10 and
macOS >= 10.13.6.

`identity` - *String*

Name of certificate to use when signing.
Default to be selected with respect to `provisioning-profile` and `platform` from `keychain` or keychain by system default.

Signing platform `mas` will look for `3rd Party Mac Developer Application: * (*)`, and platform `darwin` will look for `Developer ID Application: * (*)` by default.

`identity-validation` - *Boolean*

Flag to enable/disable validation for the signing identity. If enabled, the `identity` provided will be validated in the `keychain` specified.
Default to `true`.

`keychain` - *String*

The keychain name.
Default to system default keychain.

`ignore` - *RegExp|Function|Array.<(RegExp|Function)>*

Regex, function or an array of regex's and functions that signal skipping signing a file.
Elements of other types are treated as `RegExp`.
Default to `undefined`.

`platform` - *String*

Build platform of Electron.
Allowed values: `darwin`, `mas`.
Default to auto detect by presence of `Squirrel.framework` within the application bundle.

`pre-auto-entitlements` - *Boolean*

Flag to enable/disable automation of `com.apple.security.application-groups` in entitlements file and update `Info.plist` with `ElectronTeamID`.

`restrict` - *Boolean*

**To be deprecated, see `signature-flags`.**
Restrict dyld loading. See doc about this [code signature flag](https://developer.apple.com/documentation/security/seccodesignatureflags/kseccodesignaturerestrict?language=objc) for more details. Disabled by default.

`signature-flags` - *String*
Comma separated string or array for [code signature flag](https://developer.apple.com/documentation/security/seccodesignatureflags?language=objc). Default to `undefined`.

`signature-size` - *Number*
Provide a value to be passed to `codesign` along with the `--signature-size` flag, to work around the *signature too large to embed* issue. A value of `12000` should do it - see the [FAQ](https://github.com/electron/electron-osx-sign/wiki/FAQ) for details. Default to `undefined`.

`strict-verify` - *Boolean|String|Array.<String>*

Flag to enable/disable `--strict` flag when verifying the signed application bundle.
If provided as a string, each component should be separated with comma (`,`).
If provided as an array, each item should be a string corresponding to a component.
Default to `true`.

`timestamp` - *String*

Specify the URL of the timestamp authority server, default to server provided by Apple. Please note that this default server may not support signatures not furnished by Apple.
Disable the timestamp service with `none`.

`type` - *String*

Allowed values: `development`, `distribution`.
Default to `distribution`.

`version` - *String*

Build version of Electron.
Values may be like: `1.1.1`, `1.2.0`.
Default to latest Electron version.

It is recommended to utilize this option for best support of specific Electron versions. This may trigger pre/post operations for signing: For example, automation of setting `com.apple.security.application-groups` in entitlements file and of updating `Info.plist` with `ElectronTeamID` is enabled for all versions starting from `1.1.1`; set `pre-auto-entitlements` option to `false` to disable this feature.

## Debug

As of release v0.3.1, external module `debug` is used to display logs and messages; remember to `export DEBUG=electron-osx-sign*` when necessary.

## Test

The project's configured to run automated tests on CircleCI.

If you wish to manually test the module, first comment out `opts.identity` in `test/basic.js` to enable auto discovery. Then run the command `npm test` from the dev directory.

When this command is run for the first time: `electron-download` will download macOS Electron releases defined in `test/config.json`, and save to `~/.electron/`, which might take up less than 1GB of disk space.

A successful testing should look something like:

```
$ npm test

> electron-osx-sign@0.4.17 pretest electron-osx-sign
> rimraf test/work

> electron-osx-sign@0.4.17 test electron-osx-sign
> standard && tape test
