Verify QR Code Signatures in Document Leave feedback
On this page
GroupDocs.Signature for Python via .NET provides functionality to verify QR code signatures in documents. This guide demonstrates how to verify QR code signatures using Python.
Here’s a simple example showing how to verify QR code signatures in a document:
import groupdocs.signature as signature
from groupdocs.signature.options import QrCodeVerifyOptions
import groupdocs.signature.domain as gsd
# Initialize signature
with signature.Signature("sample_signed.pdf") as sign:
# Create verification options
options = QrCodeVerifyOptions()
options.text = "https://www.example.com"
options.match_type = gsd.TextMatchType.Contains
options.all_pages = True # verify on all pages
# Verify signatures
result = sign.verify(options)
if result.is_valid:
print("Document was verified successfully!")
else:
print("Document failed verification process.")
Here’s an example showing more advanced verification options:
import groupdocs.signature as signature
from groupdocs.signature.options import QrCodeVerifyOptions
# Initialize signature
with signature.Signature("sample_signed.pdf") as sign:
# Create verification options with advanced settings
options = QrCodeVerifyOptions()
options.text = "https://www.example.com"
options.match_type = signature.TextMatchType.Exact # require exact match
options.qr_code_type = signature.QrCodeType.QR # specify QR code type
options.all_pages = False # verify only on specific pages
options.page_numbers = [1, 2] # verify on pages 1 and 2
# Verify signatures
result = sign.verify(options)
if result.is_valid:
print("Document was verified successfully!")
# Print verification details
for signature in result.succeeded:
print(f"Found valid QR code: {signature.text}")
else:
print("Document failed verification process.")
# Print failed verification details
for signature in result.failed:
print(f"Invalid QR code: {signature.text}")
You may easily run the code above and see the feature in action in our GitHub examples:
Along with the full-featured Python library, we provide simple but powerful free online apps.
To verify PDF, Word, Excel, PowerPoint, and other documents you can use the online apps from the GroupDocs.Signature App Product Family.
