But Digital Signature is related with cryptograpy (??), no role for
password.
pls excuse if i am wrong..
OpenOffice documents are saved as ZIP compressed archives. The save with password function uses a ZIP file password. It is a simple encryption scheme, not like any of the algorithms used in OpenPGP.

Are you sure about that? I just did a test save in OpenOffice's writer and it does not use a zip file password when saving with a password as the zip file it created was completely unzippable without a password. Instead certain files inside the zip it created when told to save with a password were encrypted, which were content.xml, settings.xml, and styles.xml. "meta.xml" was not encryped and a "META-INF" subfolder in the zip file had an file inside named "manifest.xml" that was also not encrypted that had information about the encryption being used in it (blowfish CFB for me), the integrity checking method (SHA1 hashes), several initialization vectors values, several salt values, the file sizes of the encrypted files, and other info. So, I doubt it is using a simple encryption scheme in for its encryption.
