Simwigo is a cross-platform tool, written in Go, to simplify the deployment of a web service.

It is easy to use and user-friendly. It also implements features to facilitate file exchange.

The web service architecture is based on the powerful Gin framework. Pterm is used to provide a nice and neat display.

It implements simple security mechanisms to protect the exposure of the service, such as TLS, by automatically generating a TLS certificate using Let’s Encrypt or by using personal certificates.

This is not the case with efficient but not secure tools such as SimpleHttpServer or http.Server (python).

Moreover, for more security it is possible to use authentication by API tokens.


  • /ping : Ping the server to check if you can join him.
  • /print : Print details of incoming requests (interesting when exploiting an XXS for example).
  • /file/upload : To upload files.
  • /file/download/{filename} : To download files.
  • /file/list : List all available files.


  simwigo [OPTIONS]

Application Options:
      --autotls     Enable TLS using Let's Encrypt
      --self-cert   Auto generates self-signed TLS certificates (dangerous)
      --rsa         Force the use of RSA to generate TLS certificates (default=EDCSA)
  -a, --api         Enable authorization api key
      --no-debug    Disable Debug mode: no output
      --light       Light mode: disable colored mode
  -p, --port=       Port to listen (default: 8000)
  -i=               Interface to listen (default:
      --cert=       Path to TLS certificate file
      --key=        Path to TLS KEY file
      --temp=       Path to a temporary directory
      --cache=      Path to a cache directory
      --dir=        Enable directory listing (dangerous)
  -d, --domain=     Domain to specify for Let's Encrypt
  -l, --white-list= White list IP separated by comma (,)


This tool was developed with security in mind, to keep the web server secure as possible.


You can easily deploy a web server using TLS.

Below are the rules to enable TLS :

  • By using --autotls option. This feature support Let’s Encrypt (recommended).
  • By using --self-cert option. This will automatically generate self-signed certificates. Please use it only on a lab network (not safe).
  • By providing your own certificates.


It is highly recommended to enable the API option. This feature will generate an API key that must be provided to access sensitive API routes.

White listing

A white list system allows you to specify which IPs will be able to access the server and reject all requests from unknown IPs.

simwigo --autotls --api --white-list,,


Upload file

curl -H "X-API-Key: XXXXXXXXXXXXXX" -F "[email protected]/tmp/test.txt"

# Windows PowerShell

req = New-Object System.Net.WebClient
$req.Headers.Add("X-API-Key", "XXXXXXXXXXXXXX")
$req.UploadFile("", ".\Desktop\file.txt")

Download file


# Windows PowerShell

Invoke-WebRequest '' -Headers @{"X-API-Key" = "lhztfbMjNk7TbncxUebt"}

Print incoming requests

When print api route is accessed, it will prompt the details:
