jekyll-email-munge

https://github.com/framallo/jekyll-email-munge

A Jekyll plugin for address munging — defending email addresses on public sites against bulk harvesters. Stacks five independently-effective techniques (AES-128-GCM encryption, JS conversion, click trigger, CSS-hidden decoy, SVG noscript fallback) so scrapers see ciphertext while humans see a normal mailto link. Drop in a Liquid tag — `{% munge_email "[email protected]" %}` — and the plugin handles encryption at build time, the decoder script, and the fallback markup.
