Fernet Encryption is a plugin that can be used to encrypt and decrypt data in WordPress using fernet.
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.
To encrypt data simply use $token = fernet_encrypt( 'YOUR MESSAGE' )
in your code.
To decrypt the data simply use fernet_decrypt( $token )
in your code.
You can use the following shortcode to encrypt:
[fernet-encrypt]YOUR MESSAGE[/fernet-encrypt]
You can use the following shortcode to decrypt:
[fernet-decrypt]YOUR-FERNET-TOKEN[/fernet-decrypt]
