SubZero

❄️ Research project for the development of SubFinder core API v2

Installing SubZero

If you're interested in testing out the alpha version of SubFinder's next command-line application experience:

Note: this is alpha software. It's not perfect, and will be eventually merged into SubFinder's main project. This is purely for those interested in early testing to help out with development.

$ go get -u github.com/subfinder/research/subzero

Command-Line Usage

You can enumerate a domain, like google.com, and optionally use the --verbose flag for more information.

$ subzero enumerate google.com --verbose

Get help for any command to learn about more options.

$ subzero help enumerate

Run Tests

$ cd /path/to/research
$ GOCACHE=off go test -v -run=. ./... -race
# just core
$ GOCACHE=off go test -v -run=. ./core -race

Why?

That's a great question, and I hope these reasons will make sense:

• Reduce boilerplate code needed to add or develop new sudomain Sources
• Utilize the interface type in golang to define our internal API semantics.
• Provide tests and examples of all its functionality.
• Ensure a solid foundation for future tools to be built upon (CLI, HTTP/REST API)
