LogMeIn Rescue - 6 digit PIN code (Or Windows 10 S mode) Blocked Port 1935 Troubleshooting. Toggle Mac App Store and identified developers and close the window. The last component of the.app file is the code signature contained within the CodeSignature folder. The purpose of the code signature is to verify that every byte within the.app file is exactly the same as when it was signed by it’s creator (specified by the signing identity).
macOS and Windows code signing is supported. Windows is dual code-signed (SHA1 & SHA256 hashing algorithms).
On a macOS development machine, a valid and appropriate identity from your keychain will be automatically used.
Tip
See article Notarizing your Electron application.
Env Name | Description |
---|---|
CSC_LINK | The HTTPS link (or base64-encoded data, or file:// link, or local path) to certificate (*.p12 or *.pfx file). Shorthand ~/ is supported (home directory). |
CSC_KEY_PASSWORD | The password to decrypt the certificate given in CSC_LINK . |
CSC_NAME | macOS-only Name of certificate (to retrieve from login.keychain). Useful on a development machine (not on CI) if you have several identities (otherwise don’t specify it). |
CSC_IDENTITY_AUTO_DISCOVERY | true or false . Defaults to true — on a macOS development machine valid and appropriate identity from your keychain will be automatically used. |
CSC_KEYCHAIN | The keychain name. Used if CSC_LINK is not specified. Defaults to system default keychain. |
Tip
If you are building Windows on macOS and need to set a different certificate and password (than the ones set in
CSC_*
env vars) you can use WIN_CSC_LINK
and WIN_CSC_KEY_PASSWORD
.Windows¶
To sign an app on Windows, there are two types of certificates:
- EV Code Signing Certificate
- Code Signing Certificate
Both certificates work with auto-update. The regular (and often cheaper) Code Signing Certificate shows a warning during installation that goes away once enough users installed your application and you’ve built up trust. The EV Certificate has more trust and thus works immediately without any warnings. However, it is not possible to export the EV Certificate as it is bound to a physical USB dongle. Thus, you can’t export the certificate for signing code on a CI, such as AppVeyor.
If you are using an EV Certificate, you need to provide win.certificateSubjectName in your electron-builder configuration.
If you use Windows 7, please ensure that PowerShell is updated to version 3.0.
If you are on Linux or Mac and you want sign a Windows app using EV Code Signing Certificate, please use the guide for Unix systems.
Travis, AppVeyor and other CI Servers¶
To sign app on build server you need to set
CSC_LINK
, CSC_KEY_PASSWORD
:- Export certificate. Consider to not use special characters (for bash[1]) in the password because “values are not escaped when your builds are executed”.
- Encode file to base64 (macOS:
base64 -i yourFile.p12 -o envValue.txt
, Linux:base64 yourFile.p12 > envValue.txt
).
Or upload
*.p12
file (e.g. on Google Drive, use direct link generator to get correct download link).- Set
CSC_LINK
andCSC_KEY_PASSWORD
environment variables. See Travis or AppVeyor documentation. Recommended to set it in the CI Project Settings, not in the.travis.yml
/appveyor.yml
. If you use link to file (not base64 encoded data), make sure to escape special characters (for bash[1]) accordingly.
In case of AppVeyor, don’t forget to click on lock icon to “Toggle variable encryption”.
Keep in mind that Windows is not able to handle enviroment variable values longer than 8192 characters, thus if the base64 representation of your certificate exceeds that limit, try re-exporting the certificate without including all the certificates in the certification path (they are not necessary, but the Certificate Manager export wizard ticks the option by default), otherwise the encoded value will be truncated.

Where to Buy Code Signing Certificate¶
See Get a code signing certificate for Windows (platform: “Microsoft Authenticode”).Please note — Gatekeeper only recognises Apple digital certificates.
How to Export Certificate on macOS¶
- Open Keychain.
- Select
login
keychain, andMy Certificates
category. - Select all required certificates (hint: use cmd-click to select several):
Developer ID Application:
to sign app for macOS.3rd Party Mac Developer Application:
and3rd Party Mac Developer Installer:
to sign app for MAS (Mac App Store).Developer ID Application:
andDeveloper ID Installer
to sign app and installer for distribution outside of the Mac App Store.Mac Developer:
to sign development builds for testing Mac App Store submissions (mas-dev
target). You also need a provisioning profile in the working directory that matches this certificate and the device being used for testing.
Please note – you can select as many certificates as needed. No restrictions on electron-builder side. All selected certificates will be imported into temporary keychain on CI server.4. Best app to change ical font on mac. Open context menu and

.How to Disable Code Signing During the Build Process on macOS¶
To disable Code Signing when building for macOS leave all the above vars unset except for
CSC_IDENTITY_AUTO_DISCOVERY
which needs to be set to false
. This can be done by running export CSC_IDENTITY_AUTO_DISCOVERY=false
. Another way — set
mac.identity
to null
. You can pass aditional configuration using CLI as well: -c.mac.identity=null
.Today, we released our WordPress.com Desktop app on Windows, the app takes advantage of all the work put in creating the Calypso app which is the Javascript client code that powers WordPress.com, which is all open source.
To build the desktop apps, we use Electron which bundles Javascript, Node and the Chromium browser together into a cross-platform application. Electron works on Windows, OS X and Linux and is used by Slack, Github and Microsoft among others.
The tricky part distributing the apps is getting them packaged properly for each platform, and to sign these packages properly. Downloadable and distributed software is much different than server side web apps that we’re used to.
You can see an improperly signed application with the “Publisher: Unknown”
So here’s a quick guide on lessons learned, that might help you get your installer signed properly from the start. Note, the instructions are for signing an already built Setup.exe installer. For info on building the installer, see electron-builder.
Get Code Signing Certificate
This wasn’t too bad, just a little time consuming and requires some real world contact with actual people. Based on this list of recommended vendors, I decided to get a standard certificate from Digicert, I imagine the process is relatively the same for the other vendors.
I ended up going with a standard certificate and not an EV cert, since the EV cert required a physical hardware device. Our company is distributed around the world and I don’t want to be the only one who can release the app.
I followed the instructions at Digicert to get a Microsoft Authenticode certificate. It required providing company information and a corporate phone number to call and verify. Be sure to know how to retrieve calls or voice mail from your company number.
Certificate Format
After receiving the certificate, you download it to your computer’s keychain, on Mac it works best to use Safari or Chrome to do this. From your keychain, you can export the certificate to a PFX/P12 file.
If you are signing on Windows, you can use the P12 certificate directly.
If you are signing on OS X, you need to convert it into a usable format. I found converting to a SPC and PVK files worked best. One rub, to convert the certificates you need to use a newer version of openssl than what ships with OS X, install using
brew install openssl
Signing Application
It is recommended to sign the apps using at minimum SHA1 algorithm,
signtool.exe
defaults to SHA1, unfortunately signcode
defaults to MD5, so you must pass in a flag to change. Using SHA256 or SHA512 is even better, but not as compatible so most still use SHA1.Additionally adding a timestamp signature cryptographically proves that your package was signed at a specific time, which offers two benefits: (1) The signature remains valid even after the signing certificate expires since the signing took place when the certificate was valid. (2) It can be used by the operating system as a compatibility measure, future packages might be required to be signed differently, with a timestamp you ensure the package was compatible at that time.
On Windows
On Windows, you can use the
signtool.exe
, which is installed with Visual Studio and Windows SDK. The tool is found on my Windows 10 installation under C:Program Files (x86)Windows Kits10binx86signtool.exe
Using the P12 file directly, you simply can sign using, replace PASS with your passcode:
signtool.exe sign /t http://timestamp.digicert.com /f code.p12 /p PASS App-Setup.exe
You can also use the tool to verify a signature is valid:
signtool.exe verify /pa /v App-Setup.exe
On OS X
On OS X, once you have the SPC and PVK file, you can sign using
signcode
that ships with the Mono tools. Install using brew install mono
You can then sign using the following command, you’ll be prompted for your passcode.

You can verify it got signed properly using the signtool.exe on Windows, or right-click and select “Properties » Digital Signatures”.
Code Sign Mac App Store
When you run the installer now you should see the “Verified publisher” filled in with your certificate information.

Microsoft SmartScreen
Codesign Mac App
Even after signing your app properly, there is an extra step of protection called the SmartScreen which can display during installation. It is my understanding that this is displayed based on the reputation of your certificate. So as more valid installs occur, it will go away and not display to users.
In an attempt to improve our reputation, I saw one recommendation to Microsoft’s Hardware Dev Center which has a file signing section. I registered our company and walked through uploading a signed sample app. I’m not sure if this helps or not, but I figured it couldn’t hurt and might improve our certificate’s reputation.
Thanks to Eric Lawrence for offering valuable suggestions and reviewing the draft.
