Encrypt a Shared Folder*
AES 256-bit encryption protects data by blocking off all unauthorized access attempts. Once a shared folder is encrypted, anyone without the encryption key will not be able to use the encrypted data even if they remove the hard drives from your Synology RackStation and mount it on their device.
To encrypt a shared folder:
- Select a shared folder that you want to encrypt, and then click Edit.
- Tick Encrypt this shared folder in the window that appears, and then enter an encryption key in the Encryption key field, and enter the same key again in the Confirm key field to confirm it.
- Tick Mount automatically on startup to mount the encrypted folder automatically for access. If this checkbox is not checked, the encrypted folder will be unmounted next time Synology RackStation restarts.
To access an unmounted folder:
- Select the unmounted, encrypted shared folder.
- Click Encryption and select Mount.
- Import or manually enter the encryption key.
Note:
- The names of files and folders within encrypted shared folders cannot exceed 143 English characters or 43 Asian characters.
- Shared folders can also be encrypted at the time of creation.
