### Examples

Shows how to sign a saved PDF document digitally and timestamp it.

```python
doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
builder.writeln('Signed PDF contents.')
# Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
# to modify how that method converts the document to .PDF.
options = aw.saving.PdfSaveOptions()
# Create a digital signature and assign it to our SaveOptions object to sign the document when we save it to PDF.
certificate_holder = aw.digitalsignatures.CertificateHolder.create(file_name=MY_DIR + 'morzal.pfx', password='aw')
options.digital_signature_details = aw.saving.PdfDigitalSignatureDetails(certificate_holder, 'Test Signing', 'Aspose Office', datetime.datetime.now())
# Create a timestamp authority-verified timestamp.
options.digital_signature_details.timestamp_settings = aw.saving.PdfDigitalSignatureTimestampSettings(server_url='https://freetsa.org/tsr', user_name='JohnDoe', password='MyPassword')
# The default lifespan of the timestamp is 100 seconds.
# We can set our timeout period via the constructor.
options.digital_signature_details.timestamp_settings = aw.saving.PdfDigitalSignatureTimestampSettings(server_url='https://freetsa.org/tsr', user_name='JohnDoe', password='MyPassword', timeout=datetime.timedelta(minutes=30))
self.assertEqual(1800.0, options.digital_signature_details.timestamp_settings.timeout.total_seconds)
self.assertEqual('https://freetsa.org/tsr', options.digital_signature_details.timestamp_settings.server_url)
self.assertEqual('JohnDoe', options.digital_signature_details.timestamp_settings.user_name)
self.assertEqual('MyPassword', options.digital_signature_details.timestamp_settings.password)
# The "Save" method will apply our signature to the output document at this time.
doc.save(file_name=ARTIFACTS_DIR + 'PdfSaveOptions.PdfDigitalSignatureTimestamp.pdf', save_options=options)
```
