Sending HTTP Get to Bittorent tracker - Where's info_hash and peer_id?

Question

I'm trying to send a HTTP get request to a tracker. But I don't know where the info_hash and peer_id are and I need them as parameters. According to bittorent specifications the info_hash is the metafile's info "info_hash: urlencoded 20-byte SHA1 hash of the value of the info key from the Metainfo file."and the peer_id "is allowed to be any value"

But when I put the properly URL encoded info key as the info_hash, and arbitrarly put something for the peer_id I get this error: d14:failure reason20:Torrent unauthorisede

Can someone give me an example where the info_hash is in this file?

Using Java if it matters. Lmk if I need to give more info.

Answer 1

The info dictionary in your example starts at

infod13:

You must determine the info data and calculate the SHA1 of the info data. After that you must to URL encode the SHA1.

info_hash: urlencoded 20-byte SHA1 hash of the value of the info key from the Metainfo file. Note that the value will be a bencoded dictionary, given the definition of the info key above.

There is an example written in Qt which i think it might help you. (Qt5.2.1/5.2.1/gcc_64/examples/network/torrent) You can find it online here qt torrent
