// Start by disallowing all permissions
encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);

// Extend permissions to allow editing or modifying annotations
encryptionDetails.setPermissions(PdfPermissions.MODIFY_ANNOTATIONS | PdfPermissions.DOCUMENT_ASSEMBLY);
saveOptions.setEncryptionDetails(encryptionDetails);
