General

How do I backup my encryption key?

The configuration is stored in a file at wp-content/gf_encryption_configuration.php
You should keep a copy of this file backed up somewhere. If you ever lose the key that is stored in it then there is no way to decrypt your data.

Does the plugin work with WordPress Multisite?

Yes, Gravity Forms Encryption works with WordPress Multisite. The only limitation at this time is the same encryption key is used for all sites on the multisite.

What encryption is used?

AES 256 encryption is used with the openssl PHP extension to encrypted the data. It uses a 32 byte key as the encryption passphrase.

What are the minimum requirements?

Gravity Forms Encryption requires PHP 7.2 or later with the openssl PHP extension.

How are files encrypted from the File Upload field?

Files are encrypted after upload and are stored in the same location an unencrypted file upload would be stored. Which defaults to a directory under wp-content/uploads/gravity_forms
The encrypted files are stored with a randomly generated string of characters to not reveal anything about what the file is.
The original filename is stored encrypted in the database along with the Entry so when downloading the file it will preserve the original name.

Can my encrypted data still be sent through email?

We don’t recommend this since email is not a secure channel, so there is not setting in the plugin to enable this. However, if you do need this functionality you can add the following filter to your functions.php to allow the email to include the encrypted fields. Please Contact Us and let us know if you do use this and if enough people want this feature we may add the setting.

add_filter( ‘plugins_loaded’, function() {
remove_filter( ‘gform_merge_tag_filter’, ‘gf_encryption_gform_merge_tag_filter’, 10, 4 );
});
