I think a better long term option would be to remove the protocols (http/s) from the links and have it try only https by default, then a --insecure cmd option that will additionally try http if an https connection fails.

• This pull request is left here to keep jcadduono's notice/comment stay here as a future "todo" work. This is a dirty solution which should not be used!

The best solution would be to add the --insecure option as mentioned in the above comment.
Feel free to implement the solution for future problems that may occour on SSL certificates.

how about adding "--insecure" as a fallback if the first download fails?
We are comparing the hashes anyway after the download.
