Most of your questions are addressed here: https://www.debian.org/ Yes, Debian is a free operating system, meaning that you are allowed to use, modify and give the software to others, as long as you limit yourself to the "free" repository. Other licenses may apply to the "non-free" section. Here's how you verify downloaded installation media: https://www.debian.org/CD/verify Packaes are signed, the package manager takes care of verifying their signatures before install: https://www.debian.org/doc/manuals/securing-debian-manual/deb-pack-sign.en.html Enjoy -- tomás
