PDF Signature: Hide CN from PFX but Show Timestamp and Date on Signature Appearance

Hi Aspose team,

I’m using the POST /pdf/{name}/sign API to digitally sign a PDF file with a .pfx certificate. Here’s the request I’m sending via curl:

bash

CopyEdit

curl --location 'https://api.aspose.cloud/v3.0/pdf/file333.pdf/sign' \
--header 'authorization: Bearer <token>' \
--header 'Content-Type: application/json' \
--data '{
  "SignaturePath": "fred.pfx",
  "FormFieldName": "sign1",
  "SignatureType": "PKCS7",
  "ShowDate": true,
  "Password": "apples",
  "Appearance": "rajat_sign.png",
  "Reason": "reason",
  "Visible": true,
  "Rectangle": {
    "LLX": 148,
    "LLY": 456,
    "URX": 29,
    "URY": 541
  },
  "ShowProperties": false
}'

Issue:

  • I want to display the signing date and timestamp.
  • I do not want to show the CN=fred (the name in the .pfx file).
  • When I set "ShowProperties": false, the date/time does not show either.
  • If I set "ShowProperties": true, then the CN=fred appears, which I don’t want to show.
