Remarks
- The signature applied by PDFSign is an approval signature. The PDF file can be signed and countersigned several times.
- This signature must correspond to a control of PDF file (its minimum size will be set to 1 X 1 mm²). The Signature control can be invisible but we advise you to associate it with a caption or an image in order for the user to see this signature and to click it.
- The encrypted PDF files (with password) are not supported.
- The PDF files whose version is later than PDF 1.5 will be saved in version PDF 1.4 before they can be signed.
- Caution: For Acrobat to recognize a signed PDF file, the organization that creates the signing certificate must be in the Adobe Approved Trust List (Adobe Authorized Trust List) or in the Certified Document Services program (CDS).
If the certificate is not recognized, Acrobat will display the following message: "At least one signature has problems".
