. The userPassword and the ownerPassword can be null or have zero length. In this case the ownerPassword is replaced by a random string. The open permissions for the document can be AllowPrinting, AllowModifyContents, AllowCopy, AllowModifyAnnotations, AllowFillIn, AllowScreenReaders, AllowAssembly and AllowDegradedPrinting. The permissions can be combined by ORing them.
