Password protection: Protecting and encrypting workbooks

To encrypt and password-protect a given file, use the File > Encrypt command, specify your password consisting of at least 6 characters and choose the encryption algorithm.

If a workbook is encrypted and password-protected, the "shield" toolbar button becomes green.

Note: GS-Calc uses standard ODF (OpenDocument) encryption procedure and encrypt all information (tables, styles, charts, images, settings etc.) that a workbook can contains. However, (file)names of the inserted images are left unencrypted in the *.ods file.
