This is a Qubes ad.
And that’s fine, but why Qubes insists it’s not Linux while booting the Linux kernel, running xen, using xfce as the primary desktop, and being listed on disteowatch seems like a weird marketing choice to me. Your primary audience knows what Linux is, so what is the motivation behind claiming “Qubes is not Linux”?



cbz files are not encrypted, they’re just zip files full of images with the xtension changed to “cbz”. Similarly, CBR files are the same thing, but using rar compression.
If you are referring to zip “password protection”, then I guess that’s technically valid, although why anyone would rely on such trivially-cracked security is beyond me.
