Examples
Shows how to digitally sign documents.
# Create an X.509 certificate from a PKCS#12 store, which should contain a private key.
certificate_holder = aw.digitalsignatures.CertificateHolder.create(file_name=MY_DIR + 'morzal.pfx', password='aw')
# Create a comment and date which will be applied with our new digital signature.
sign_options = aw.digitalsignatures.SignOptions()
sign_options.comments = 'My comment'
sign_options.sign_time = datetime.datetime.now()
# Take an unsigned document from the local file system via a file stream,
# then create a signed copy of it determined by the filename of the output file stream.
