electron-osx-sign

Codesign Electron macOS apps

About

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 like network access require additional work.

It is worth noting as well that starting from Electron v1.1.1, a new mechanism was introduced to satisfy IPC communications (see electron#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 Electron specifications; please file us an issue if having any suggestions or experiencing difficulties code signing your products.

Please visit our Wiki hosted here on GitHub for walk-throughs and notes from past projects shipped with electron-packager and electron-osx-sign.

NB: The signing procedure implemented in this package is based on what described in Mac App Store Submission Guide.

Installation

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

# 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

Check out electron-osx-sign guide for suggestions on setting up your environment and workflow for distribution or development.

From the Command Line

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

Examples

• To sign a distribution version by default:

  electron-osx-sign path/to/my.app

• To sign development version:

  electron-osx-sign path/to/my.app --type=development

• 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:

  electron-osx-sign path/to/my.app --provisioning-profile=path/to/my.provisioningprofile

• To specify the entitlements file:

  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:

  electron-osx-sign path/to/my.app --version=0.34.0

Run electron-osx-sign --help or see electron-osx-sign-usage.txt for CLI-specific options.

From the API

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

Example:

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.

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

Example:

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

opts - Options

Required

app - String

Path to the application package. Needs file extension .app.

Optional

binaries - Array

Path to additional binaries that will be signed along with built-ins of Electron. Default to undefined.

entitlements - String

Path to entitlements file for signing the app. Default to built-in entitlements file, Sandbox enabled for Mac App Store platform. See default.entitlements.mas.plist or default.entitlements.darwin.plist with respect to your platform.

entitlements-inherit - String

Path to child entitlements which inherit the security settings for signing frameworks and bundles of a distribution. This option only applies when signing with entitlements. See default.entitlements.mas.inherit.plist or default.entitlements.darwin.inherit.plist with respect to your platform.

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.

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 - String

Regex or function that signals ignoring a file before signing. 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. Default to true.

pre-embed-provisioning-profile - Boolean

Flag to enable/disable embedding of provisioning profile in the current working directory. Default to true.

provisioning-profile - String

Path to provisioning profile.

requirements - String

Specify the criteria that you recommend to be used to evaluate the code signature. See more info from https://developer.apple.com/library/mac/documentation/Security/Conceptual/CodeSigningGuide/RequirementLang/RequirementLang.html Default to undefined.

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

Specify whether to sign app for development or for distribution. 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.

cb - Callback

err - Error

electron-osx-flat

From the Command Line

electron-osx-flat app [options ...]

Example:

electron-osx-flat path/to/my.app

From the API

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

Example:

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

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

As developer certificates are required for codesign on macOS, this module is difficult to be tested via online build services. If you wish to test out this module, enter:

npm test

from the dev directory, and tell us if all tests should pass.

When this command is fun for the first time: electron-download will download all major releases of Electron available for macOS from 0.24.0, 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@0.4.6 pretest electron-osx-sign
> rimraf test/work

> electron-osx-sign@0.4.6 test electron-osx-sign
> standard && tape test
