Thinking about it ,I am not sure how uTorrent or P2P clients really work after all. So the option of checking what most people have is out of the question… How does uTorrent make sure that the chunk received is the chunk it should be getting.

Let’s say there are files $A$, $B$, $C$ among 10 seeders and I am the receiver. So, what is used instead? I’ve been reading that some asymmetric functions are used and that files are encrypted using the destination's public key.īut I am unable to wrap my head around it and say* “ok, this will work in P2P”*. I want to share with you a way you can 00:04 add a torrent if the only information 00:08 available was this info hash so if there 00. Then later on, I found out that a checksum isn't used at all for this purpose. If the next day, I connect the external disk before starting qbittorrent, it should recognize that the ext disk Q is now there, and I suspect it will just do checking for a small sample of the torrents that are on Q. So all a hacker has to do is make a file with smaller sum and then fill in the rest with garbage that way file would have equivalent checksum, but completely different content. I can download new torrents into C: and seed from those torrents that are on C. Which didn't make sense for obvious reasons… for example it's not hard to get the same sum for different numbers. I am very new to concepts of cryptography so bear with me and feel free to fill in any information that may seem obvious but something you think someone may not know.Īt first I was under impression that people use checksums to determine if files are legit or not.
