# Using Plugins

  • This page explains about the usage of Qv2ray plugin system
  • To use a plugin, you need at least Qv2ray v2.5.0-pre1 BuildVersion: 5264

# What is a plugin

Technically said, a Qv2ray Plugin is a shared library that implements QvPlugin interface, which in order to extent the functionality of Qv2ray.

Qv2ray Plugin extends Qv2ray's functionality, which allows you use more features. By leveraging plugins, Qv2ray can even run without using V2Ray core at all.

Builtin Shadowsocks Support vs QvPlugin-SS

It is a common gotcha that people think Qv2ray needs QvPlugin-SS to support Shadowsocks. Qv2ray already has built-in Shadowsocks support (opens new window) from V2Ray Core, which will suffice general use cases. Therefore, you don't necessarily need to use QvPlugin-SS.

Though strongly unrecommended, however, if you insist on using outdated/deprecated ciphers (for example, rc4-md5), you may need QvPlugin-SS to make them work. Servers with SIP003 plugins (for example, simple-obfs (opens new window), kcptun (opens new window) and v2ray-plugin (opens new window)) will also require QvPlugin-SS to work.
