Fernet Encryption for WordPress

Secure data in WordPress with Fernet Encryption.

Description

Setup your Key

To setup your key, you need to add the following line to your wp-config file.

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.
