Hashids 👾

Hashids is a small open-source library that generates short, unique, non-sequential ids from numbers. 💎

It converts numbers like 347 into strings like “yr8”, or array of numbers like [27, 986] into “3kTMd”. 🌀

You can also decode those ids back. 🔙

Available in 🔥 :
• JavaScript
• .NET
• Java
• PHP
• Ruby
• Python
• Swift
• ...

🔸🔹🔸🔹

Usage example in JavaScript 🤙🏻 :

var hashids = new Hashids("this is my salt", 8, "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890");

var id = hashids.encode(1, 2, 3); 
// Output : GlaHquq0

var numbers = hashids.decode(id);
// Output : [1, 2, 3]

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. ☝🏻
