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