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.

Fernet Encryption is a plugin that can be used to encrypt and decrypt data in WordPress using fernet.
Development was originally sponsered by Access Networks.
<h3>Setup your Key</h3>
To setup your key, you need to add the following line to your wp-config file.
<pre><code>`
</code></pre>
define( ‘FERNET_KEY’, ‘YOUR_FERNET_KEY’ ); 
 `
If you choose not to setup your key, you will need to save a copy of the one provided upon activation of the plugin.
IMPORTANT: Changing your WordPress salts will invalidate the default Fernet key provided.
<h3>How to Use</h3>
To encrypt data simply use <code>$token = fernet_encrypt( 'YOUR MESSAGE' )</code> in your code.
To decrypt the data simply use <code>fernet_decrypt( $token )</code> in your code.
You can use the following shortcode to encrypt:
<pre><code>[fernet-encrypt]YOUR MESSAGE[/fernet-encrypt]
</code></pre>
You can use the following shortcode to decrypt:
<pre><code>[fernet-decrypt]YOUR-FERNET-TOKEN[/fernet-decrypt]
</code></pre>
We have also added useful helper functions:
<ul>
<li>fernet_get_post_meta</li>
<li>fernet_add_post_meta</li>
<li>fernet_update_post_meta</li>
<li>fernet_get_user_meta</li>
<li>fernet_add_user_meta</li>
<li>fernet_update_user_meta</li>
<li>fernet_add_option</li>
<li>fernet_get_option</li>
<li>fernet_update_option</li>
</ul>
