Emacs wants you to install unauthenticated code off of a wiki; I can help.
Are you a programmer? Do you use a text editor? Do you install any 3rd-party functionality into that text editor?
If you use Vim, you’ve probably installed a few vimballs from vim.org, a website only available over HTTP. Vimballs are fairly opaque; if you’ve installed one, chances are you didn’t audit the code.
If you use Emacs, you’ve probably installed some packages from ELPA or MELPA using package.el; in Emacs’s default configuration, ELPA is accessed over HTTP, and until recently MELPA’s documentation recommended HTTP as well.
When you install un-signed code into your editor that you downloaded over an unencrypted, unauthenticated transport like HTTP, you might as well be installing malware. This is not a joke or exaggeration: you really might be.1 You have no assurance that you’re not being exploited by someone on your local network, by someone on your ISP’s network, the NSA, the CIA, or whoever else.
