While working on boot.dev’s Go Playground, I came across a very strange error. The standard library’s fmt.Printf() function prints nothing to the console when called. Nothing. For those of you who are familiar with the function, when compiled to a “normal” executable fmt.
The age of information is not what we all hoped it would be. We successfully digitized the majority of human knowledge, and we even made it freely accessible to most. Now the problem is different, we have too much information.
HMACs and MACs are authentication codes and are often the backbone of JWT authentication systems. A Message Authentication Code (MAC) is a string of bits that depends on a secret key and is sent with a message to prove the message wasn’t tampered with.
PGP, or its open-source alternative, GPG, is a program used to encrypt data such that only an authorized party can decrypt it. In this introduction, we will cover its use-cases and a high-level overview of the algorithms involved. Both programs (and others) adhere to the OpenPGP protocol.
In this quick tutorial, we’ll build a robust video (or music) streaming API using Node JS. Don’t worry, it’s surprisingly easy since we will be utilizing a modern protocol, HTTP Live Streaming, or HLS. HLS allows us to serve large media files as many smaller files.
Users love convenience. If your goal is to make it easy for users to register with your app or website, then implementing the “Sign in with Google” option should be at the top of your priority list.
Scrypt is a slow-by-design key derivation function designed to create strong cryptographic keys. Simply put, the purpose of the Scrypt hash is to create a fingerprint of its input data but to do it very slowly.
Rust and Go are two of the industry’s biggest successes when it comes to developing modern programming languages. Both languages compete in terms of backend web development, and it’s a fierce competition. Golang and Rust are new languages, have growing communities, and are fast and efficient.
Custom toggle switches are a pain to code from scratch. So many lines for such a simple UI widget! In this quick tutorial, we will learn how to build a fully encapsulated toggle switch component in Vue.js. The component we’re building is used currently on boot.dev’s login page.
SHA-2 (Secure Hash Algorithm 2), of which SHA-256 is a part, is one of the most popular hash algorithms around. In this article, we will break down each step of the cryptographic algorithm and work through a real example by hand.
