HTTPS explained with carrier pigeons ⚡️

Cryptography can be a hard subject to understand. It’s full of mathematical proofs. 🤷🏻‍♂️

But unless you are actually developing cryptographic systems, much of that complexity is not necessary to understand what is going on at a high level. 💎

If you opened this article hoping to create the next HTTPS protocol, I’m sorry to say that pigeons won’t be enough. 🕊

Otherwise, brew some coffee and enjoy the article. ☕️

How does RSA work❓

RSA is an asymmetric system , which means that a key pair will be generated, a public key and a private key, obviously you keep your private key secure and pass around the public one. 🌍

The algorithm was published in the 70’s by Ron Rivest, Adi Shamir, and Leonard Adleman, hence RSA , and it sort of implement’s a trapdoor function such as Diffie’s one. 🛅

RSA is rather slow so it’s hardly used to encrypt data , more frequently it is used to encrypt and pass around symmetric keys which can actually deal with encryption at a faster speed. 🏃🏻

The Difference Between SHA-1, SHA-2 and SHA-256 Hash Algorithms 🔐

If you have heard about “SHA” in its many forms, but are not totally sure what it’s an acronym for or why it’s important, we’re going to try to shine a little bit of light on that here today. 🌈

Before we can get to SHA itself though, we need to run through what a hash is, and then we’ll get into how SSL certificates use hashes to form digital signatures. 🌐

These are critical concepts to understand before you’ll be able to follow what SHA-1 and SHA-2 are. ☝🏻
