Features

Multi-network

Shareaza can connect to

, G2, eDonkey and BitTorrent. Shareaza hashes its files for all networks, and then distributes those hash values on G2. This allows Shareaza to download one file from several networks at once. When another client connected to G2 finds such a file, it is given the hash values for all networks and can search on the other networks with their respective hash values, which increases the number of sources and the download speed of the file. Shareaza also uses its G2 network to find more sources for torrents.

Security filter

The Shareaza client has some basic content filters including a forced child and optional adult pornography filter, and some other optional filters such as a filter for files encumbered with Digital rights management (DRM). Shareaza's security filters can also be extended with user-defined keywords and/or IP addresses. Later versions of Shareaza allow for the use of

. The filters are editable inside Shareaza, and can be exported from the application to be shared with others.

Plugins

Shareaza implements a framework for additional plugins. The Shareaza installer ships several plugins. Most of them are used to read and strip off built in metadata from the files being hashed and convert it to an external XML based format, or to decode

plugins can also be used, for example, ''Sharemonkey'', which will add a link inside Shareaza when downloading or searching copyrighted material from where it can be legally downloaded.

Skins

The client can have almost all parts of the

Modes

Shareaza has three user modes. The first one is for normal users. This mode is the default mode and provides a clean, trimmed GUI. Users will not be able to make major changes to settings in this mode, but will be able to make use of the most essential functions, like searching and downloading. The second mode is for

In this mode, users can see different tabs (windows) simultaneously, providing a lot of control about the things happening. This mode also makes it possible to personalize the look of the client to perfectly fit the needs of the respective user.

History

In mid-2002 Stokes released the first version of a

client he had written and dubbed "Shareaza". It was from the beginning a client with the aim of having features other gnutella clients did not have. Over the next two years Stokes coded in support for the eDonkey 2000 network, BitTorrent and a rewritten gnutella-based protocol which he named

. On June 1, 2004 Stokes released the Shareaza source code under the GPL-2.0-or-later license (which coincided with the release of Shareaza version 2.0). Shareaza joined

No ads, no spyware, no guilting you to upgrade to a commercial version", stating that the developers " ouldn'tstand that kind of crap." It has remained as such in each subsequent release. From the first version Shareaza has supported swarming, metadata, library management, and automatic file hashing.

From 1 January 2008 the new owner of the domain shareaza.com, Discordia Ltd. used this update check mechanism to suggest to users that ShareazaV4 (and later ShareazaV5, V6, and V7) was an update to the original Shareaza client. Since version 2.3.1.0, released on 3 January 2008, the original Shareaza has linked to the Shareaza pages at sourceforge.net.

Trademark registration by iMesh

On January 10, 2008, the new owners of Shareaza.com, Discordia Ltd (

Inc.), filed for trademark registration of the Shareaza name in an attempt to stop the original developers from using the name, claiming that the first-ever use was on December 17, 2007. The Shareaza Development Team obtained legal representation to challenge the registration and a legal defense fund was set up. The development team appointed William Erwin to handle the donations; it was stated that he had been paid by iMesh to sabotage the defense, and that he had stolen the money donated. The trademark was awarded to iMesh after the development team had given up defending the trademark.
