Using Sublime Text for Go Development

If you're new to golang then before you start setup your workspace, firstly watch this video Writing, building, installing, and testing Go code.

Usually after installing go, I'm running the following commands to make GOPATH available for my user

mkdir -p ~/Documents/My/gocode/src/github.com/shamil

shamil

package main

import (
	"encoding/base64"
	"encoding/json"
	"flag"
	"fmt"
	"net/url"
	"os"
	"os/user"

nmap -p 443 --script ssl-cert gnupg.org

The -p 443 specifies to scan port 443 only. All ports will be scanned if it is omitted, and the certificate details for any SSL service that is found will be displayed. The --script ssl-cert tells the Nmap scripting engine to run only the ssl-cert script. From the doc, this script "(r)etrieves a server's SSL certificate. The amount of information printed about the certificate depends on the verbosity level."

Sample output:

Starting Nmap 7.40 ( https://nmap.org ) at 2017-11-01 13:35 PDT

Nmap scan report for gnupg.org (217.69.76.60)
