Dasharo Openness Score

What is Dasharo Openness Score

Have you ever wondered how open is your open-source firmware? How much closed-source and binary blobs is still there? Dasharo Openness Score utility answers those questions.

Dasharo Openness is a report showing the open-source code to closed-source code ratio in the Dasharo firmware images. The results are also presented as a pie chart for better visual representation of the firmware image components and their share percentage.

Dasharo Openness Score utility is capable of parsing Dasharo coreboot-based images as well as vendor UEFI images. Thanks to that one can easily compare how many bytes of the firmware have been liberated as well as by how much the Trusted Computing Base (TCB) has been reduced.

Dasharo Openness Score utility not only support Dasharo coreboot-based images, but also many more coreboot distributions like heads.

How does it work?

The utility leverages various tools like coreboot's cbfstool or LongSoft's UEFIExtract to decompose and parse the firmware images. The output from the utilities is used to detect the image type and then to calculate the openness metrics.
