Crittografia/Decrittografia ODS File:

Per crittografare un file ODS, caricare il file e passare la password effettiva aWorkbookSettings.setPassword()prima di salvarlo. Il file crittografato di output ODS può essere aperto solo in OpenOffice. Per decrittografare un file ODS, caricare il file fornendo la password nel fileLoadOptions.setPassword() . Una volta caricato il file, chiama functionCartella di lavoro.unprotect() con la password effettiva come argomento e infine passare null aWorkbook.getWorkbookSettings().setPassword().

// The path to the documents directory.
static String sourceDir = Utils.Get_SourceDirectory();
static String outputDir = Utils.Get_OutputDirectory();
public static void main(String[] args) throws Exception {
//Encrypt an ODS file
//Encrypted ODS file can only be opened in OpenOffice as Excel does not support encrypted ODS files
//Initialize loading options
LoadOptions loadOptions = new LoadOptions(LoadFormat.ODS);
// Instantiate a Workbook object.
// Open an ODS file.
Workbook workbook = new Workbook(sourceDir + "sampleODSFile.ods", loadOptions);
//Encryption options are not effective for ODS files
// Password protect the file.
workbook.getSettings().setPassword("1234");
// Save the excel file.
workbook.save(outputDir + "outputEncryptedODSFile.ods");
//Decrypt ODS file
//Decrypted ODS file can be opened both in Excel and OpenOffice
// Set original password
loadOptions.setPassword("1234");
// Load the encrypted ODS file with the appropriate load options
Workbook encrypted = new Workbook(sourceDir + "sampleEncryptedODSFile.ods", loadOptions);
// Unprotect the workbook
encrypted.unprotect("1234");
// Set the password to null
encrypted.getSettings().setPassword(null);
// Save the decrypted ODS file
encrypted.save(outputDir + "outputDecryptedODSFile.ods");
// Print message
System.out.println("Encryption and Decryption applied successfully on ODS file.");
