Disabling attachment object encryption

By default, the attachment files (.NLO files) created and stored by DAOS are encrypted. While not recommended, you can disable the encryption.


  1. Open the Server document for the server that you want to disable attachment object encryption. Note that keeping encryption enabled is recommended because it provides stronger security.
  2. Click the DAOS tab.
  3. In the DAOS object encryption field, select None.
    Note: This option is equivalent to the notes.ini setting DAOS_ENCRYPT_NLO=0 that was used prior to Domino 12. If you used DAOS_ENCRYPT_NLO=0, although not recommended, it is honored in Domino 12.
  4. Save the document.
  5. Restart Domino:
    restart server
