Field EncryptionProNew in 5.0+

Each field includes the ability to optionally encrypt its submission data. Simply toggle the Encrypt field data setting inside the form builder for any field you wish to have encrypted. Freeform will take care of the rest.

For each field that is encrypted and contains submission data, the database row column will contain a prefix of encrypted: and then the encryption string. Freeform will decrypt the submission data for exports, email notifications, integrations, and viewing submission data inside the control panel and front end (if you have templates set up to show it).

Field encryption uses the Craft Security Key (usually CRAFT_SECURITY_KEY in your .env file), so be sure to use the same key across multiple environments.

If you wish to use a different security key for Freeform specifically, you can specify a custom key in the Secret Key setting under the Form Sessions area of the Form Behavior settings page (CP → Freeform → Settings → Form Behavior).

Encryption is not retroactive. Each submission will need to be resaved to update older submissions.
