Node-HTML-Crypt

Self-decrypting JavaScript for general purpose spam defense.

Because the internet really hasn’t changed that much in the last twelve years.™

Ported from the excellent HTML_Crypt package by Mike Dransfield and Christian Weiske which was first released on September 8, 2002.

Installation

npm install html-crypt

Usage

var crypt = require('html-crypt');
crypt('<a href="mailto:[email protected]>Karl Lagerfeld</a>');

The above outputs a script tag with some gnarly looking JavaScript that that in turn self-decrypts to the given string on page load. Believe it or not, this will still thwart most spam-bots.

With Express 3.x

Adding a Jade helper is easy. Add the following to your Express app…

app.locals.crypt = require('html-crypt');

…and you'll get a helper function in your Jade templates:

p!= crypt('<a href="mailto:[email protected]">Karl Lagerfeld</a>')

To-Do

Write some tests.
