EasyRPZ - Hosts to RPZ converter

EasyRPZ is a command-line tool written in Go for converting a list of domain names and IP addresses into a Response Policy Zone (RPZ) file format. It allows you to create an RPZ file that can be used for DNS filtering and blocking specific domains.

Usage

easyrpz \
  -i inputFile1.hosts \
  -i http://example.com/inputFile2.hosts \
  -e excludeFile1.txt \
  -e http://example.com/excludeFile2.txt \
  -o outputFile.rpz

This command will convert the input hosts files inputFile1.hosts and inputFile2.hosts (retrieved from the URL http://example.com/inputFile2.hosts), exclude the domains listed in excludeFile1.txt and excludeFile2.txt (retrieved from the URLs http://example.com/excludeFile2.txt), and generate the RPZ file outputFile.rpz.

Flags

• -i: Input file paths or URLs (required, can be specified multiple times)
• -o: Output file path (required)
• -e: File paths or URLs containing domains to exclude (optional, can be specified multiple times)
• -w: Include wildcard blocking

Features

• Converts a list of domain names and IP addresses into RPZ format.

You will need Go (version 1.16 or above).

Run the following command to build the program:

./make

After the build is successful, you will have an executable file named easyrpz in the current directory.
