Client Features

Protocol Encryption

We have full support for Protocol Encryption. It is not enabled by default, but can be enabled in the BitTorrent section of the client preferences.
Protocol Encryption (PE) is a joint specification between Azureus and BitTorrent. It is designed to bypass throttling and/or blocking of BitTorrent traffic by an ISP.
You can choose Protocol Encryption's mode of operation in BitTorrent. Here is an explanation of the various options you can choose from:
  • Disabled: Does not encrypt outgoing connections, but will accept encrypted incoming connections.
  • Enabled: Attempts to encrypt outgoing connections, but will fall back to an unencrypted mode if the connection fails.
  • Force: Attempts to encrypt outgoing connections, and will NOT fall back to an unencrypted mode if the connection fails.
  • Allow legacy incoming connections enables or disables incoming legacy (non-encrypted) connections.

All modes will accept incoming encrypted connections (and the encryption is 2-way)!
It is generally not recommended to turn off "Allow legacy incoming connections", unless you must have only encrypted connections.

DHT and Peer Exchange

µTorrent supports DHT and Peer Exchange. DHT support also includes trackerless torrents and downloading of .torrent files through magnet links.

See 'What is DHT?' for more details on DHT itself.

Web Interface

***We have a new zero-conf web interface called µTorrent Remote in the µTorrent 3.0 alpha. We also have our classic WebUI available in most versions of the client under Web UI in the preferences.

The Mac client also supports both of these WebUIs as of version 1.5.

UPnP (Universal Plug'n'Play)

***We have full UPnP support on all supported OSes. It is enabled by default and is used to automatically forward ports in your router. This often will succeed, though in some cases, manual forwarding is required. See How do I forward ports? for an explanation of what UPnP is for and other info related to forwarding ports.


RSS feeds

µTorrent supports both viewing feeds and automatic downloading of torrents from RSS feeds.


Super Seeding mode

µTorrent supports super seeding. Double click on a torrent and check the Initial Seeding box to turn it on. For an explanation of what Super Seeding is, read this page

Please note that Super Seeding should ONLY be used if you are the -ONLY- seeder in the swarm, with no exceptions. It is also only effective with at least 2 peers in the swarm, and should generally not be used when you have high upload speeds.


HTTPS (SSL) and UDP trackers

SSL is supported for trackers and RSS feeds! UDP tracker support is now in place as well.


Boss Key

The boss key is a function that hides and unhides the client window and the system tray icon when you press the hotkey. It optionally allows password-based authentication to prevent someone from unhiding it.

You can set the key by going to the General section of the preferences, clicking on the box under Boss Key, and pressing the keys you want to use. Type in a letter or number while holding Ctrl, Alt or Shift. Alternatively, you can use one of the Function keys on the top row of the keyboard. This will be a global hotkey that can be activated while any application has focus. To clear the boss key, click on the box and press either Delete or Backspace.
