- Implement tests for writing data files with rotation, ensuring backups are created only on changes.
- Verify that old backups are rotated correctly and the maximum number of backups is maintained.
- Test restoration of backups while preserving the current state as a backup.
- Utilize Vitest for testing framework and manage temporary file storage during tests.
- Enhanced the getRecipientsByGroup function to filter and add active trainers from users.json to the newsletter recipients list.
- Ensured that duplicate emails are not added to the recipients array.
This commit introduces a mechanism to handle multiple possible encryption keys for data decryption across various modules, including auth.js, members.js, newsletter.js, and encryption.js. It adds functions to retrieve potential old keys for migration purposes and updates the decryption logic to attempt decryption with these keys. Additionally, it includes warnings for users when old keys are used and provides guidance for re-encrypting data. This enhancement improves data migration capabilities and ensures backward compatibility with previously encrypted data.
