Security with Go

By: John Daniel Leon

Overview of this book

Go is becoming more and more popular as a language for security experts. Its wide use in server and cloud environments, its speed and ease of use, and its evident capabilities for data analysis, have made it a prime choice for developers who need to think about security. Security with Go is the first Golang security book, and it is useful for both blue team and red team applications. With this book, you will learn how to write secure software, monitor your systems, secure your data, attack systems, and extract information. Defensive topics include cryptography, forensics, packet capturing, and building secure web applications. Offensive topics include brute force, port scanning, packet injection, web scraping, social engineering, and post exploitation techniques.

Packages

Packages are just directories. Every directory is its own package. Creating subdirectories creates a new package. Having no subpackages leads to a flat hierarchy. Subdirectories are used just for organizing code.

Packages should be stored in the src folder of your $GOPATH variable.

A package name should match the folder name or be named main. A main package means that it is not intended to be imported into another application, but meant to compile and run as a program. Packages are imported using the import keyword.

You can import packages individually:

import "fmt" 

Alternatively, you can import multiple packages at once by wrapping them with parenthesis:

import (
"fmt"
"log"
)
