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>

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.

Please note that I’ve moved away from WordPress for the time being. I have no plans to continue updating my plugins. If someone was thinking of forking this project, now would be the time.
Semisecure Login Reimagined increases the security of the login process by using a combination of public and secret-key encryption to encrypt the password on the client-side when a user logs in. JavaScript is required to enable encryption. It is most useful for situations where SSL is not available, but the administrator wishes to have some additional security measures in place without sacrificing convenience.
This plugin is a “re-imagining” of the original <a href="https://wordpress.org/extend/plugins/semisecure-login/" title="Semisecure Login" rel="ugc">Semisecure Login</a> (which used one-way MD5 hashing). This version works with the new phpass hashed passwords that WordPress uses, as well as maintaining backwards compatibility with the older (pre WordPress 2.5) MD5 hashed passwords. Theoretically, it will also work with any other hashing algorithm (because this plugin simply adds an extra layer in the process rather than trying to authenticate anything itself).
This plugin requires PHP to be compiled with openssl support, which is a pretty standard option for most hosts.
