LimeWire is a free and open source peer-to-peer file sharing client for the Gnutella network. It is released under the GNU General Public License. The program allows users to share files using the Gnutella peer-to-peer protocol. It was the first file sharing program to support firewall-to-firewall file transfers, a feature introduced in version 4.2, which was released in November 2004.
LimeWire is written in Java and therefore runs on any computer with the Java virtual machine installed. To facilitate installation for casual users, the developers release installation packages for Microsoft Windows, Mac OS X, and for Linux, in RPM format. Classic Mac OS (Mac OS 9 and before) support has been dropped with LimeWire 4.0.10.
LimeWire uses the SHA-1 and Tiger tree hash cryptographically secure hash functions to ensure that downloaded data is uncompromised. Although researchers have identified possible vulnerabilities in the SHA1 algorithm, because LimeWire does not rely on SHA1 alone, these vulnerabilities do not have many adverse implications for LimeWire's verification of downloaded files.
The Windows version of LimeWire installer includes a stripped-down version of Sun's Java installer which will download and install version 1.5 of the Java Runtime Environment (JRE) if it detects the machine doesn't have Java, or has a version of Java below version 1.4.1.
