GSoC 19 POW BitTorrent Client:

A BitTorrent Client to create, seed and download studies of C. Elegans through torrents. This Framework has built in Data Integrity Checks and utilizes Google Drives to View, Download and Upload desired .torrent files!

Getting Started

This will guide you through setting up this Framework, this repository is split into 2 parts: [All functionality via Command Line Interface]

1) Uploading:

This involves generating the Message Digest for Data integrity checks, creating torrents and seeding their contents to other BitTorrent peers. The torrents are then posted to Google Drives from where they can be searched/accessed based on descriptions that you provide for independent researchers.

2) Downloading:

This involves selecting one of many torrents hosted within Google Drive, Adding torrent to BitTorrent client and waiting for the desired contents to Download from peers into a specified local directory. Check for Data Integrity and you are good to go!

Requirements

• python libtorrent used here.

[python-libtorrent requires python2 and has package manager support for only Debian.]

sudo apt install python-libtorrent

• install from requirements.txt:

  
  pip3 install -r requirements.txt 

<br/>

## Set it up!

### For Uploading:

- First **Place contents within ~/Uploading**. Then run script **seed_final** as shown. This will create a torrent, the **torrent is named by the SHA hash of the contents**, then the client will begin seeding to other peers.

python2 Uploading/seed_final.py

**P.S:** Seed **indefinitely** as shown below

- Second **post torrent to Google Drive**. Also add a description for the contents of your torrent as shown below:

<br/>

### For Downloading:

- **Get** the desired torrent file **based on descriptions** by specifying its serial number as shown below.

![](images/get_torrent.png)

As shown below:
- **Start** the BitTorrent Download daemon:

python3 Downloading/torrent_cli.py start &

- **Add the torrent** and specify the directory to download contents into:

python3 Downloading/torrent_cli.py add '.torrent file' -d 'Download directory'

- To **watch the download progress** use: (ctrl + c to exit view):

watch python3 torrent_cli.py status

![](images/downloading.png)

- After **waiting for 100% download completion**, check for **data integrity**:

python3 integrity.py 'path of .torrent file' 'Path of downloaded contents'

(Data integrity check shown below!)
