Hey there! Recently, I encountered some encoding issues. Then I realized that, looks like I haven't seen any articles give a crispy yet interesting explanation on Base64/Base64URL/Base32 encoding! Ah! I should write one! So, grab your gear, and let's decode these fascinating encoding schemes together! The Enigma of Base64 Encoding Why do we need Base64? Imagine you're sending a beautiful picture postcard through the digital world, but the postal service (the internet, in this case) only handles plain text. How do you do it? Enter Base64 encoding – it's like magic that transforms binary data (like images) into a text format that can easily travel through the internet without getting corrupted. Base64 takes your binary data and represents it as text using 64 different characters: In more details, it will: It's widely used in email attachments, data URLs in web pages, and anywhere you need to squeeze binary data into text-only zones. A simple text like "Hello!" when encoded in Base64, turns into "SGVsbG8h". Usage of Base64 in Data URIs Data URIs (Uniform Resource Identifiers) offer a powerful way to embed binary data, such as images, directly into HTML or CSS files, using Base64 encoding. This method eliminates the need for external file references, resulting in fewer HTTP requests and potentially faster page loads. Here's how it works in practice: Embedding an Image in HTML Using Data URI Let's say you have a small logo or icon that you want to include directly in your HTML page without linking to an external file. You can use Base64 to encode the…
