數位簽名
此Python程式碼展示了如何使用IronPDF庫對現有PDF進行加密簽名並創建帶有數位簽名的PDF。
如何在 Python 中生成數位簽章
- 下載 Python 模組以生成數位簽章
- 渲染一個新的 PDF 文件
- 實例化 PdfSignature 將類和匯入數字證書
- 如有需要，請增加其他資訊。
- 使用
簽名簽署文件的方法
from ironpdf import *
# Cryptographically sign an existing PDF in 1 line of code!
PdfSignature(r".\certificates\IronSoftware.p12", "123456").SignPdfFile("any.pdf")
##### Advanced example for more control #####
# Step 1. Create a PDF
renderer = ChromePdfRenderer()
doc = renderer.RenderHtmlAsPdf("<h1>Testing 2048 bit digital security</h1>")
# Step 2. Create a Signature.
# You may create a .pfx or .p12 PDF signing certificate using Adobe Acrobat Reader.
# Read: https://helpx.adobe.com/acrobat/using/digital-ids.html
signature = PdfSignature(r"certificates\IronSoftware.pfx", "123456")
# Step 3. Optional signing options and a handwritten signature graphic
signature.SigningContact = "support@ironsoftware.com"
signature.SigningLocation = "Chicago, USA"
signature.SigningReason = "To show how to sign a PDF"
# Step 4. Sign the PDF with the PdfSignature. Multiple signing certificates may be used
doc.Sign(signature)
# Step 5. The PDF is not signed until saved to file, steam or byte array.
doc.SaveAs("signed.pdf")
