Update for BitTorrent Protocol Specification v2

[paxter]

Would be nice, if this tool would be updated with the latest BitTorrent Protocol Specification v2 described here: http://bittorrent.org/beps/bep_0052.html
Especially the part with stronger hash functions (SHA2-256) would be nice.

SHA-1 chosen-prefix attacks are now in the USD 10k-100k range. This presents a very real threat, for example against bittorrent-distributed software that might be used by dissidents or whistleblowers.

BitTorrent v2 should be high priority now.

BitTorrent v2 and hybrid torrent file generation is being implemented at the moment.

@sbrudenell What potential attack vector do you see could be used against a torrent file, or its usage?

I admit I don't have a specific vector in mind, but sha1 is used in many places in the torrent protocol so it's hard to convince myself there are no attacks.

Anything new? Looks like the "moment" takes a lot of time. :D
