AI Analysis

●MidCozy

Shadow DOM obfuscation when dozens of email protectors already exist.

Strengths

•PHP 8.4's new DOM APIs enable clean server-side parsing
•Custom elements reveal content only on user interaction
•Works with AJAX, htmx, and dynamically loaded content

Weaknesses

•Email obfuscation is a solved problem with many established tools
•Shadow DOM approach doesn't fundamentally improve on existing techniques

Post Description

Hey HN!

After reading this article about email obfuscation [0] a few weeks ago, I build html-obfuscator. And I'm awfully proud of the result!

I know obfuscation is not new (haha)... but I think I found a very nice way to obfuscate content without disrupting the user experience (closed shadow root!).

I hope the demo [1] makes it clear enough how it works.

I'd love to get a few people to look at this and give me feedback. Negative is ok, maybe I learn something! ;)) And I'm also a sucker for GitHub stars. At least 10 would be amazing...

Cheers, Rasso
