Get hash for each file inside a torrent !?

[GoogleCodeExporter]

Hello, I'm trying to match some files with the files inside a torrent, but 
comparing just the file size isn't enough since there are many files that have 
the exact same file size but different content :(

So is there a way to get the hash for each file inside a torrent file !?

I've found here 
http://stackoverflow.com/questions/2572521/extract-the-sha1-hash-from-a-torrent-
file how to verify the files, but that's not what I want... I want is to get 
the hash for every file inside the torrent and compare it with other random 
files...

    # get files from torrent
    torrentFiles = []
    tPath = '123.torrent'
    t = lt.bdecode(open(tPath, 'rb').read())
    info = lt.torrent_info(t)
    for x in info.files():
        torrentFiles.append([x.path, x.size, x.hash!? ])

I can see two approaches:

1. Download the files in the torrent, then calculate the hashes of those files.

2. Don't calculate the hashes of files, but instead calculate the piece hashes 
of the files you want to compare with, and compare those piece hashes with the 
piece hashes in the .torrent file. Make sure to make sure you get the piece 
alignment right, since pieces are not necessarily aligned to file boundaries.

btw. this doesn't seem like a bug report or feature request for libtorrent.
