The encryption module allows the secure storage of personal data of study participants such as date of birth, name etc.

This module allows individual Castor fields (study variables) to be stored in an encrypted manner. This means that the data is stored in the database in the form of a random code. To view the data that lies behind this code, the user needs to have an encryption/decryption key.

By encrypting fields and through the dedicated 'Encrypt' user right, you can restrict user access to fields that contain personal data.

Getting started

To get started with Encryption, follow these steps:

1. Enable the encryption module for your study and set it up for the fields in your study.
2. Encrypt the fields (study variables) that will contain encrypted personal data.
3. Assign users Encrypt rights so that they can add, view and edit encrypted data.
4. Learn how to work with encryption fields in data entry.
