PdfDigitalSignatureHashAlgorithm enumeration

Specifies a digital hash algorithm used by a digital signature.

Members

Name	Description
SHA256	SHA-256 hash algorithm.
SHA384	SHA-384 hash algorithm.
SHA512	SHA-512 hash algorithm.
RIPE_MD160	RIPEMD-160 hash algorithm.

Examples

Shows how to sign a generated PDF document.

doc = aw.Document()
builder = aw.DocumentBuilder(doc)
builder.writeln('Contents of signed PDF.')
certificate_holder = aw.digitalsignatures.CertificateHolder.create(MY_DIR + 'morzal.pfx', 'aw')
# 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()
# Configure the "digital_signature_details" object of the "SaveOptions" object to
# digitally sign the document as we render it with the "save" method.
signing_time = datetime.now()
import aspose.words.saving as aws
options.digital_signature_details = aw.saving.PdfDigitalSignatureDetails(certificate_holder, 'Test Signing', 'My Office', signing_time)
options.digital_signature_details.hash_algorithm = aw.saving.PdfDigitalSignatureHashAlgorithm.RIPE_MD160
self.assertEqual('Test Signing', options.digital_signature_details.reason)
self.assertEqual('My Office', options.digital_signature_details.location)
self.assertEqual(signing_time.astimezone(timezone.utc), options.digital_signature_details.signature_date)
doc.save(ARTIFACTS_DIR + 'PdfSaveOptions.pdf_digital_signature.pdf', options)
