As far as I know, HTTP is prone to man-in-the-middle attacks. As such, the repositories in Alpine Linux or the CentOS Mirrors are not HTTPS.
In the olden days, having HTTPS used to be an expensive matter. It cost server CPU time and the certificates weren't free. But it’s 2022 now, and we have plenty of ways to overcome those problems and security has been top priority than ever!
How can we obtain binaries smarter?
Also is this a problem in the wider Linux community? I.e., Ubuntu, Linux Mint, openSUSE, etc.?
