  1. Whitelist the certificate

    The first step is to whitelist the Certificate your signatures will be authenticating against. You can launch the software prior to this, but you will not be able to make a websocket connection, as there is no GUI for the warning dialogues to display in, causing an immediate disconnect.

    • Open a terminal or cmd prompt and execute the appropriate command for your OS:

      Note: the --whitelist flag can be substituted withed --allow or -a

      OS Command
      Windows java -jar "%PROGRAMFILES%\QZ Tray\qz-tray.jar" --whitelist "path\to\digital-certificate.txt"
      ... and optionally copy "%appdata%\qz\allowed.dat" "%programdata%\qz\allowed.dat" see also #749.
      Linux java -jar /opt/qz-tray/qz-tray.jar --whitelist "path/to/digital-certificate.txt"
      macOS java -jar /Applications/QZ\ --whitelist "path/to/digital-certificate.txt"
    • Verify the entry Successfully added YOUR COMPANY to allowed list in the log displayed in the command prompt

    • An allowed.dat file is created with the finger print of the Intermediate Certificate (digital-certificate.txt).

      OS Location
      Windows %APPDATA%\qz\allowed.dat
      Linux ~/.qz/allowed.dat
      macOS ~/Library/Application\ Support/qz/allowed.dat
  2. Launch QZ Tray in headless mode

    • Run the software from the command line using the --headless or -h flag:

      OS Command
      Windows java -Xms512m -jar "%PROGRAMFILES%\QZ Tray\qz-tray.jar" --headless
      Linux java -Xms512m -jar /opt/qz-tray/qz-tray.jar --headless
      macOS java -Xms512m -jar /Applications/QZ\ --headless
