Golang: Quick-Start & Installation Guide

INTRODUCTION:

Go is an open-source programming language maintained by Google. It is easy to learn, has built-in concurrency, and has a robust standard library. It has a large ecosystem of partners, communities, and tools. Golang (Go) is a programming language, and it is becoming more and more widely used and very popular. I have seen many exciting tools that are made from and written in Go.

Since we know that Golang means GO, which is not pre-installed in Kali Linux and is not installed by default in Kali Linux.

So, I thought publishing a quick-start guide could be a good idea because many people do not know how to install Golang on Kali Linux or any other operating system.

So, before we do the installation part, we go through several key benefits in the field of cybersecurity.

Nuclei offers several key benefits in the field of cybersecurity:

1. Strong Typing and Memory Safety:

Go enforces strong typing and memory safety, which helps me prevent programming errors and some buffer overflows, null pointers, and memory leaks. These features are to secure the writing of codes and mitigate vulnerabilities.

2. Concurrency and Scalability:

Go is built with built-in support for lightweight concurrency through the channels, which makes it easy to write concurrent and scalable programs. In the realm of cybersecurity, this will handle large volumes of network traffic, perform parallel processing of security-related tasks, or create efficient scanning tools.

3. Standard Library:

Go has rich standard libraries that include comprehensive support for networking, cryptography, and secure communication protocols. And this eliminates the need for external dependencies in many cases, reducing the attack surface and ensuring the applications are secured during development.

4. Efficiency:

Go is a very efficient runtime and has a low memory footprint. This is advantageous for developing security tools that need to process large amounts of data, such as intrusion detection systems, log analysis tools, or threat intelligence platforms.

5. Community Support:

It has huge support and an active community that contributes to the development of various security-related scenarios, in which minimizing the dependencies and ensuring a secure deployment environment are important considerations.

Overall, Go's combination of safety, concurrency, efficiency, Google support, and having a standard library makes it a compelling choice for building secure and robust cybersecurity applications. Its focus on simplicity and readability also aids in reducing the potential for human error, an essential aspect of cybersecurity.

Note: But security researchers know that if they command in the terminal [sudo apt install Golang], it installs the old version, not the latest version.

So, to install the latest versions of Golang, the below steps give you the full guide to installing Golang. Let Go install Golang (GO).

Installation of Golang

Step 1: Open your browser and just type "Golang." You can see a website called "The GO Programming Language."

Just click on [Download and install]

And then just download the latest version of Golang version 1.20.5 and it will go in your download section.

Step 2: Go into the terminal to install Golang by extracting the downloaded part. So, first, go to the terminal and get into the download folder by the following command.

And then type the command - "ls"

you will get the downloaded file [go1.20.linux-amd64.tar.gz]

And then to extract this go1.20.linux-amd64.tar.gz, we must command:

and then check by the command -ls you will get a go file

Step 3: The next step that we need to do is move the file because the reasoning behind adding and moving this file is that we must simply access this tool or file from anywhere, so let's move this thing.

You can see the go file has been moved to /usr/local.

Step 4: And then go back to the normal phase terminal by command cd..

And then type ls -la

We need to edit the .bashrc so type –

And you will get this type of interface in the terminal, so we must edit the below interface.

Write some code down like this:

And then CTRL-S [Save] the file and then exit CTRL-X [Exit]

Step 5: Similarly, add and edit by typing in the terminal:

Step 6: To check it Type – go -- version

And to get some help just type:

Summary:

In conclusion, Golang (Go) is a powerful programming language for cybersecurity applications. Its strong typing and memory safety features enhance code security. The built-in concurrency support enables the development of scalable and parallel processing programs. The rich standard library eliminates external dependencies, reducing attack surfaces. Go's efficiency and low memory footprint make it ideal for handling large data volumes. With an active community, Go ensures a secure deployment environment. By following the installation steps provided, you can easily harness the benefits of Golang in cybersecurity.
