Checksumming

I don't necessarily agree with everything this site is trying to do, but given that the download servers used by your website aren't backed by HTTPS you should at least be offering checksumming as a way to make sure downloads aren't being modified or tampered with by an outside source who may not have the best intentions towards this project, of which the media industry is likely to be the biggest. This will help keep your users safer than the status quo, and I hope you choose to adopt it consequently.
