httpx is a fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library. It is designed to maintain result reliability with an increased number of threads.

Features

httpx

  • Simple and modular code base making it easy to contribute.
  • Fast And fully configurable flags to probe multiple elements.
  • Supports multiple HTTP based probings.
  • Smart auto fallback from https to http as default.
  • Supports hosts, URLs and CIDR as input.
  • Handles edge cases doing retries, backoffs etc for handling WAFs.

Supported probes

URL true IP true
Title true CNAME true
Status Code true Raw HTTP false
Content Length true HTTP2 false
TLS Certificate true HTTP Pipeline false
CSP Header true Virtual host false
Line Count true Word Count true
Location Header true CDN false
Web Server true Paths false
Web Socket true Ports false

Installation Instructions

httpx requires go1.19 to install successfully. Run the following command to get the repo:

go install -v github.com/projectdiscovery/httpx/cmd/httpx@latest

Using httpx as a library

httpx can be used as a library by creating an instance of the Option struct and populating it with the same options that would be specified via CLI. Once validated, the struct should be passed to a runner instance (to be closed at the end of the program) and the RunEnumeration method should be called. Here follows a minimal example of how to do it:

package main

import (
	"log"

	"github.com/projectdiscovery/goflags"
	"github.com/projectdiscovery/gologger"
	"github.com/projectdiscovery/gologger/levels"
	"github.com/projectdiscovery/httpx/runner"
)

func main() {
	gologger.DefaultLogger.SetMaxLevel(levels.LevelVerbose) // increase the verbosity (optional)

	options := runner.Options{
		Methods: "GET",
		InputTargetHost: goflags.StringSlice{"scanme.sh", "projectdiscovery.io"},
		//InputFile: "./targetDomains.txt", // path to file containing the target domains list 
	}

	if err := options.ValidateOptions(); err != nil {
		log.Fatal(err)
	}

	httpxRunner, err := runner.New(&options)
	if err != nil {
		log.Fatal(err)
	}
	defer httpxRunner.Close()

	httpxRunner.RunEnumeration()
}

Notes

  • As default, httpx checks for HTTPS probe and fall-back to HTTP only if HTTPS is not reachable.
  • The -no-fallback flag can be used to display both HTTP and HTTPS results
  • Custom scheme for ports can be defined, for example -ports http:443,http:80,https:8443
  • The following flags should be used for specific use cases instead of running them as default with other probes:
    • -favicon,-vhost, -http2, -pipeline, -ports, -csp-probe, -tls-probe, -path
  • When using the -json flag, all the default probe results are included in the JSON output.
  • Custom resolver supports multiple protocol (doh|tcp|udp) in form of protocol:resolver:port (e.g. udp:127.0.0.1:53)
  • Invalid custom resolvers/files are ignored.
