I have made a pull request on Packer GitHub: Enable FIPS-140 builds by fredericfran-gds · Pull Request #12756 · hashicorp/packer · GitHub.
Unfortunately, there has been no traction. Any other way to notify the maintainers to have a look? thank you.
We did notice your PR, but with the end-of-year coming up, and other priorities, we haven’t yet been able to review it.
I don’t think we’ll be able to review and merge it by then, but rest assured we will definitely circle back to you on it early next year.
Thanks for opening this one!
