electron-builder给程序数字签名，出现Can't sign app: The specified timestamp server either could not be reached

使用electron-builder出现错误：Can’t sign app: The specified timestamp server either could not be reached or returned an invalid response.

解决方案：修改package.json为

{
    "build":{
        "win":{
            "icon": "public/assets/icon.ico",
            "signingHashAlgorithms": [
            	"sha256"
            ],
            "signDlls": true,
            "rfc3161TimeStampServer": "http://timestamp.digicert.com",
            "certificateFile": 证书,
            "certificatePassword": 密码,
        }
    }
}

注意signingHashAlgorithms一定只写sha256，才会应用rfc3161TimeStampServer。如果写sha1，就会应用timeStampServer
