Go Language for Encryption – Tutorial


Go, or Golang is a powerful programming language known for its simplicity, efficiency, and strong support for concurrent programming. It’s a favorite among developers for building scalable web applications, cloud services, and more.

We just released a Go course on the freeCodeCamp.org YouTube channel that walks you through building three practical Go projects. The second two projects focus on encryption. Akhil Sharma developed this course.

This course is not just about coding; it’s about building real, usable projects that can enhance your portfolio. The course is beginner-friendly but also packed with valuable insights for more experienced developers.

Go is renowned for its efficient compilation, easy-to-understand syntax, and robust standard library. It’s widely used in cloud computing, server-side applications, and systems programming. Companies like Google, Dropbox, and Docker employ Go for various applications, making it a sought-after skill in the tech industry.

Here are the projects you will create in this course:

Project 1: Health Checker

The first project is a Go-based Health Checker for websites. It allows you to check the status of any website by entering its domain name, showing whether the site is live or down. This project is a perfect way to start your journey with Go, offering hands-on experience in creating a useful tool that can be applied in various scenarios, including monitoring the health of your own web projects.

Project 2: File Encryption

Moving to a more advanced level, the second project focuses on file encryption. You will learn how to encrypt a PNG file, understand the principles of encryption, and the process of accessing encrypted files with and without a password. This project will give you a solid foundation in handling file security and encryption in Go.

Project 3: Data Encryption with Go

The third project dives into encrypting strings with Go. This project is particularly crucial as it lays the groundwork for understanding data security and encryption, which are vital skills in today’s digital world
