InfoHash and OriginalInfoHash are different

[somegenericdev]

It is entirely possible that I'm misunderstanding something, but I dont get why these two values are different. Keep in mind that I'm not manipulating the file in any way, I'm just parsing it like this

var torrentFile = File.ReadAllBytes("my.torrent");
var parser = new BencodeParser();
var torrent = parser.Parse<Torrent>(torrentFile);

and then accessing the hashes.
