EmailProtect
Version 4.0.3
WARNING! Breaking changes: Version 4.0.x does no longer support the MailEncrypt Gutenberg Block. Your email addresses are still protected
<h3>WordPress anti-spam email plugin</h3>
Simple, fast and no-config plugin to protect your email address. No need for shortcodes or blocks. EmailProtect encrypts all your email addresses in your blog.
<h3>Usage</h3>
Only install and activate EmailProtect in your WordPress backend. Now all your email addresses are protected against spam-bots. No configuration required.
<h3>How are my email addresses encrypted?</h3>
EmailProtect scans all of your posts, sites and other content for email addresses. If an email address is found, it is simply replaced with a special tag. 
If a bot is now crawling your site, the tag cannot be decrypted. Only for an actual user our script decrypts this tag and the email address can be viewed.
Example
This is what your user sees:
Here is my email address <a href="mailto:contact@code-leaf.de" rel="nofollow ugc">contact@code-leaf.de</a>.
This is what a spam-bot sees:
<pre><code>Here is my email address
<a href ="#" data-email-protect-click="eqpvcevBeqfg/ngch0fg">
 
</a>
</code></pre>

How does it work ?
wp2pgpmail includes an OpenPGP Message Encryption System in Javascript, based on <a href="http://www.haneWIN.de" rel="nofollow ugc">Herbert Hanewinkel’s work</a>. Visitors enter a message in a form, encrypt it (with the PGP public key you entered in wp2pgpmail option settings), then an e-mail is sent to you (blog admin e-mail address). The message is encrypted locally on the visitor’s computer, so no data is transfered in clear !
