GroupDocs.Signature helps Python via .NET developers secure PDF files by adding digital signatures. Strengthen your business applications with robust document protection features.
import groupdocs.signature as sg
def run():
# Use Signature to digitally sign the document
with sg.Signature('input.pdf') as signature:
# Input the digital certificate and its password
options = sg.DigitalSignOptions("certificate.pfx")
options.Password = "1234567890"
# Optionally configure how the signature will look
options.PageNumber = 1
options.Left = 50
options.Top = 50
# Finalize the document with the digital certificate
result = signature.Sign("output.pdf", options)
The GroupDocs.Signature for Python via .NET library is designed to sign all major file formats. Simplify your workflow by easily adding, verifying, updating, or removing different types of signatures.
Insert text, image, barcode, QR code, or stamp signatures precisely anywhere in supported documents. You can also manage hidden metadata, like EXIF in images, to ensure document integrity with digital signatures.
After signing, you can easily verify documents to ensure correct processing. Retrieve and manage all signatures within your files with powerful search capabilities.
Most signatures can be fully customized. You can edit text, move elements, change colors, adjust sizes, and more to fit your needs.
Our solution supports complete signature management, allowing you to delete signatures, including digital certificates, from any document when needed.
import groupdocs.signature as sg
def run():
# Load the document to be signed
with sg.Signature('input.pdf') as signature:
# Use a valid digital certificate with its corresponding password
options = sg.DigitalSignOptions("certificate.pfx")
options.Password = "1234567890"
# Add any additional text information if needed
options.Reason = "Security issue"
options.Contact = "John Smith"
options.Location = "Office D.W."
# Include an image or other options for visual representation of the signature
options.ImageFilePath = "image.png"
options.AllPages = True
options.VerticalAlignment = sg.VerticalAlignment.Center
options.HorizontalAlignment = sg.HorizontalAlignment.Left
options.Width = 60
options.Height = 80
options.Margin = sg.Padding()
options.Margin.Bottom = 10
options.Margin.Right = 10
# Save the signed document in a secure location
result = signature.Sign("output.pdf", options)
