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.

Summary

After reading this chapter, you should have a good understanding of what the Go cryptography packages are capable of. Using the examples given in this chapter as a reference, you should feel comfortable performing basic hash operations, encrypting, decrypting, generating keys, and using keys.

Additionally, you should understand the difference between symmetric and asymmetric encryption, and how it is different from hashing. You should feel comfortable with the basics of running a TLS server and connecting with a TLS client.

Remember, the goal is not to memorize every detail, but to remember what options are available so that you can choose the best tool for the job.

In the next chapter, we will look at using secure shell, also known as SSH. Authenticating with public and private key pairs and passwords is covered first, along with how to verify the remote host's key...
