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.

Cryptography is the practice of securing communications even when a third-party can view those communications. There are two-way symmetric and asymmetric encryption methods, as well as one-way hashing algorithms.

Encryption is a critical part of the modern internet. With services such as, everyone has access to trusted SSL certificates. Our entire infrastructure relies on and trusts encryption to work to keep all our confidential data secret. It is important to properly encrypt and hash data correctly, and it is easy to misconfigure a service, leaving it vulnerable or exposed.

This chapter covers examples and use cases for the following:

  • Symmetric and asymmetric encryption
  • Signing and verifying messages
  • Hashing
  • Storing passwords securely
  • Generating secure random numbers
  • Creating and using TLS/SSL certificates
