Use the shortcode `[recaptcha-protected-download]` to wrap any direct download link that you’d like reCaptcha to process.
`[recaptcha-protected-download]https://example.com/download.zip[/recaptcha-protected-download]`
Example
Here’s my `hello world` post HTML:
<pre>
Hello! This page is dynamically generated with my plugin called Content Generator which you can download from <a href="[recaptcha-protected-download]https://my-cdn.tld/static/content-generator.zip[/recaptcha-protected-download]">here</a>.

You can also download WordPress following <a href="[recaptcha-protected-download]https://wordpress.org/latest.zip[/recaptcha-protected-download]">this URL</a>
</pre>
Which is parsed as follows:
<pre>
Hello! This page is dynamically generated with my plugin called Content Generator which you can download from <a href="#rcpdl=371bce9996c0afc711648c2c4f3d5c97">here</a>.

You can also download WordPress following <a href="#rcpdl=7039e773658ed3c70d50e791ed4940fd">this URL</a>

About
This plugin opts to generate fake links (anchors) controlled with JavaScript to open up a modal once clicked to opt users to complete the anti-spam test with <a href="https://github.com/google/recaptcha/" rel="nofollow ugc">Google reCaptcha</a>.
Once a user successfully submits a test, an AJAX callback will then verify the response and parse the download.
`md5` is used to hash the download links and fetch them later once a user submits a test.
You must provide your Google reCaptcha credentials which you can obtain from <a href="https://google.com/recaptcha/admin" rel="nofollow ugc">this page</a>
Once you activate the plugin, you should now navigate to “Settings” > “reCaptcha Downlaods” (or “Options” > “reCaptcha Downlaods” for network activated plugin) and add your Google reCaptcha credentials (public and private keys) which you can obtain from https://www.google.com/recaptcha/admin
The development version of this plugin is hosted on Github, feel free to fork it, contribute and improve it, or start a new issue if you want to report something like an unusual bug.

reCaptcha Protected Downloads

Protect your downloads from bots and spiders with a shortcode and Google's no-captcha reCaptcha

Till Krüss

A lightweight plugin that protects plain email addresses and mailto links from email-harvesting robots, by encoding them into decimal and hexadecimal entities. Has an effect on the posts, pages, comments, excerpts, text widgets and other filtered content. Works without JavaScript — just simple spam protection.
To see whether all your email addresses are properly protected, use the free <a href="https://encoder.till.im/scanner?utm_source=wp-plugin&utm_medium=readme" rel="nofollow ugc">page scanner</a> tool.
Other content (like phone numbers) can be protected using <code>[encode]</code> shortcode:
<pre><code>[encode]+1 (555) 123-4567[/encode]
[encode link="tel:+15551234567"]+1 (555) 123-4567[/encode]
</code></pre>
<h4>Premium Features</h4>
<ul>
<li>Full-page protection that catches all email addresses</li>
<li>Hardened protection using JavaScript and CSS techniques</li>
<li>Improved phone number protection</li>
<li>Built-in plugin support for ACF, Jetpack, WooCommerce and many others</li>
</ul>

Email Address Encoder


This might work with page or post content, but does not with widgets. I can't recommend using this and suggest to use the plugin "Email Encoder" by Jannis Thuemming instead, since that does the job out of the box.
