Reliable download solution?
 

So, we all know, from time to time, there's corrupt downloads from sites via md5sum verification afterwards. curl, wget, etc. I'm wondering if such a tool exists that may help prevent a corrupt download?

There will never be a 100% guaranteed method to avoid corrupt downloads. What you are asking for isn't something a program could fix, it'd need to be done at the protocol level itself and as most downloads will either be TCP or UDP, that is the limiting factor at play. Naturally TCP is more resilient than UDP but UDP is faster and so more applicable to things where corruption isn't a big issue, such as live streaming.

use a torrent if possible !!!

it auto checks each chunk so for a large file like a os iso this is the best option

^ yep, the torrent protocol has this sort of stuff built in.
otherwise, you will have to check after downloading.
