#### From HTTPS to Bitcoin: How mathematics protects self-determination *by Alien Investor*\ ──────────────────────── #### Cryptography in Everyday Life Cryptography sounds like rocket science — but it has long been part of everyday life. Whenever you visit a website with “https,” use Signal, or send Bitcoin, mathematics is running in the background. It ensures that no one can secretly read your data or manipulate it. ──────────────────────── #### Symmetric and Asymmetric Cryptography Fundamentally, there are two major areas: symmetric and asymmetric cryptography. With symmetric methods, both sides encrypt and decrypt using the same secret key. This is fast and efficient. But it creates a problem: How do you exchange this key securely without it being intercepted? ──────────────────────── #### The Asymmetric Solution Asymmetric cryptography solves this by using a key pair. There is a public key, which anyone is allowed to see. And there is a private key, which should never leave your device. This allows you to encrypt messages, verify signatures — or unambiguously assign Bitcoin transactions to an address. ──────────────────────── #### Cryptography and Power Things get interesting where cryptography meets power. States, banks, and corporations would like access to everything — often citing “your safety” as the reason. They fear the loss of control that comes with true privacy. ──────────────────────── #### A Tool for Self-Determination Strong encryption turns the tables. Suddenly, the individual can effectively protect data, money, and communication from external access. That is why cryptography is not just technology. It is a tool for self-determination. Whoever controls their keys, controls their assets — whether those are messages, documents, or private keys for Bitcoin. ──────────────────────── *Money, power, Bitcoin — and OPSEC.
