Binary Data in JSON String. Something better than Base64

🔐 Binary Data in JSON String: Better than Base64 🔒

Are you tired of using Base64 to escape binary data in JSON strings? 🤔 Don't worry, we've got you covered! In this blog post, we will explore alternative methods that are more efficient and won't expand your data size. 🚀

The JSON format itself doesn't support binary data natively. So, in order to include binary data in a JSON string, it needs to be escaped. One widely-used approach for this task is Base64 encoding. Base64 is simple to implement, but it comes with a processing overhead and increases the data size by about 33%. 😓

But fear not! We've got some super cool alternatives that will make your life easier and your JSON strings leaner. Let's dive in! 💪

Problem: Base64 is a great player, but it needs an upgrade. 🏀

As mentioned earlier, Base64 encoding is commonly used to escape binary data in JSON strings. However, its drawbacks make it less than ideal. 😕

First, Base64 encoding has a high processing overhead. This means that encoding and decoding binary data can take longer, especially for larger data sets. And in today's fast-paced world, we're all about speed and efficiency! 💨

Second, Base64 expands 3 bytes of binary data into 4 characters. This expansion leads to an increased data size by around 33%. In our data-intensive world, every byte counts! We need a solution that optimizes data utilization. 📊

Solution: Introducing the 🌟 star 🌟 of the show! 🎉

Meet the Binary-to-Text Encoding methods! These methods allow us to encode binary data into a text-based representation that can be safely included in JSON strings. 🌈

1. Hexadecimal Encoding: In this method, each byte of binary data is converted into a two-character hexadecimal representation. For example, the byte 0x41 will be represented as "41" in the encoded string. Hexadecimal encoding is simple and widely supported. However, it doubles the size of the original data.

2. Base85 Encoding: Base85 encoding is an alternative to Base64 that uses 5 characters to represent 4 bytes of binary data. This encoding method achieves better space utilization compared to Base64, while still being human-readable. JSON parsers need to be extended to support Base85 encoding.

3. UTF-8 Encoding: If your binary data contains only a subset of valid Unicode code points, you can directly include it in a JSON string if the encoding of the JSON document is UTF-8. This method allows you to include binary data as-is, without any additional encoding overhead. However, please note that not all binary data can be represented in UTF-8.

These alternatives are worth considering for scenarios where you want to optimize performance and data size while maintaining compatibility with JSON. 😎
