## Usage

4. A lookup table of [hashes from various electron releases](https://github.com/captn3m0/electron-fingerprints/) is used to guess the version. In case of multiple matches, it returns a range of versions.
5. Get the electron version from the electron binary (WIP)
-Note that this can be run against untrusted binaries as it does not _try to run the application_. It has been tested against various file formats: zip/dmg/exe/AppImage/tar.gz etc. It extracts limited files using 7-zip.
+Note that this can be run against untrusted binaries as it does not _try to run the application_. It has been tested against various file formats: zip/dmg/exe/AppImage/tar.gz etc. It extracts limited files using 7-zip to a temporary directory at runtime if needed.
