Users are free to choose the algorithm to use. Different algorithms have different performance and results. Support both Chinese and English.

1. 安装JRE并配置环境变量。
2. 解压下载的压缩包，确保.jar文件和.dll位于同一目录下。
3. 使用命令行定位到解压目录并运行。运行命令通常为java -jar XXX.jar的形式。

1. Install JRE and configure environment variables.
2. Extract the downloaded package and make sure that the .jar file and .dll are in the same directory.
3. Use the command line to navigate to the unzipped directory and run it. The running command is usually in the form of "java-jar XXX.jar".
