      Description

      Using this tool you can download chrome extensions to .crx files from the chrome store.  https://www.maketecheasier.com/download-save-chrome-extension/  Attempting to extract these zip files using ZipArchiveInputStream, I receive the following error 

      Unexpected record signature: 0X34327243

      I attached an example .crx zip file

      VirusTotal link to prove its not malicious

      On mac and linux I am able to unzip these files using the basic unzip binaries, for example:

      15:53:37 $ unzip Lighthouse_v5.0.0.crx -d unzipped/
      Archive:  Lighthouse_v5.0.0.crx
      warning [Lighthouse_v5.0.0.crx]:  566 extra bytes at beginning or within zipfile
