Electron Builder Code Signing Download Certificate Error

By Hường Hana 7:00 PM , Leave a Comment

I'm building an Electron app and using the npm package electron-builder to build the app and installer for Windows. I'm trying to use the CSC_LINK and CSC_KEY_PASSWORD environment variables to sign the app as described here: https://github.com/electron-userland/electron-builder#travis-appveyor-and-other-ci-servers

On first try the error and stack trace is:

Unhandled rejection Error: unable to verify the first certificate at Error (native) at TLSSocket.<anonymous> (_tls_wrap.js:1065:38) at emitNone (events.js:80:13) at TLSSocket.emit (events.js:179:7) at TLSSocket._init.ssl.onclienthello.ssl.oncertcb.TLSSocket._finishInit (_tls_wrap.js:593:8) at TLSWrap.ssl.onclienthello.ssl.oncertcb.ssl.onnewsession.ssl.onhandshakedone (_tls_wrap.js:425:38) From previous event: at Object.downloadCertificate (C:\projects\presentation\Electron\node_modules\electron-builder\src\codeSign.ts:97:18) ...

I then tried setting the environment variable NODE_TLS_REJECT_UNAUTHORIZED=0 and now get a different error:

Unhandled rejection Error: Request error, status 400: Bad Request at ClientRequest.<anonymous> (C:\projects\presentation\Electron\node_modules\electron-builder\src\httpRequest.ts:36:16) ...

The particular line that is being called in electron-builder's httpRequest.ts appears to just be using Node's https module: https.request(...) https://github.com/electron-userland/electron-builder/blob/master/src/httpRequest.ts#L28

This leads me to believe there is something up with the Windows machine or certificates. I'm running this on Windows 10, node 5.9.0.

It is better to file issue to https://github.com/electron-userland/electron-builder/issues directly to get answer from the maintainers. I am active current maintainer and don't check SO, so, unlikely that you get answer quickly ;)

If issue still actual for you, file issue :)

Not certain what the root of the issue was however I was able to get everything to work by moving the file to Dropbox. I still had to set NODE_TLS_REJECT_UNAUTHORIZED=0 and CSC_LINK needed to be set without quotes:

Success: SET CSC_LINK=https://www.dropbox.com/s/path/to/file.p12?dl=1

Failed: SET CSC_LINK="https://www.dropbox.com/s/path/to/file.p12?dl=1"
