efivalidate

Important: See FORMAT.md

efivalidate is a ruby utility to take a given input EFI payload from macOS and to compare it against Apple's validation schema. Being written in ruby this can occur off-box to ensure that the utility itself hasn't been compromised

Installation

Add this line to your application's Gemfile:

gem 'efivalidate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install efivalidate

Usage

$ efivalidate

Usage: efivalidate {input.bin} [PARAMS]

  {input.bin} is a EFI payload saved using either `eficheck` or `BootRomFlash.efi`

  --download-signatures

      Attempts to download Apple's EFI signatures from their update service

  --signatures-path

      Points to a path on disk where known EFI signatures exist

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
