Hash: SHA1

Actually the last time XML torrents was proposed the first thing that
was brought up was "how do you propose to store binary data"

Using a binary format permits the EXTREMELY efficient storage of the
SHA1 hash values for pieces (20 bytes per piece instead of 40) and a
wider scalability for other binary data formats (including binary
storing of future hash type changes). 

Translations of individual fields within a torrent (such as using
UTF-8 in filenames) are controlled by the individual client
implementation, not by the format itself.

Subject: [BitTorrent] XML Torrents?


At the risk of getting stoned for heresy ;) I'm wondering why
.torrent 
files aren't implemented in XML? The recent thread confusing the
filename 
encoding scheme suggests that a human-readable, extensible, 
self-documenting format, one with many off-the-shelf tools available,
would 
be better than a new binary format.

What constraints make the binary format preferable?

BTW, the archives don't show any previous discussion of XML:
