Users can take advantage of the cryptographic protection offered by GPG to secure files and data that they want to keep well under wraps.In this guide, I will explain the options at your disposal for encrypting files using open- source software on a Linux, Mac, or Windows computer. You can then transport this digital information across distance and time, to yourself or others....

Comparing Bitcoin to barbed wire from Timothy May’s “Crypto Anarchist Manifesto” can give insight into the gravity of this seemingly abstract invention. (...

How is Bitcoin defended by energy? And what is a nonce? These questions and more are answered within!How mining works is fascinating. When I explain it to people, I enjoy seeing their face the moment their mind is blown. I’ll explain it here, but just know, I’m imagining all your faces as your minds blow!I have to start with hash functions....

Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist.Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash algorithm or SHA-256 puts Bitcoin in a different lane, where you can share your...

Message privacy, increasingly important to Bitcoiners, can be achieved with public and private key cryptography.As a Bitcoiner, you’re going to need a secure way to communicate privately, without relying on a company to encrypt your data for you. For example, freely available methods with end-to-end encryption like Telegram (not with its default option) and Signal and others are easy to use, but...

In this fun tutorial, you will learn how to generate your very own bitcoin private key.This is a fun project that will help you understand Bitcoin keys better. You'll need a pencil, paper, something to generate random output in binary (like a coin) and a computer. The purpose here is to get you doing something which will help you learn a lot,...
