Hi,

Thanks for your inquiry. Sorry for reply late for weekend.
I made an initial test with Spire.PDF for Java Version:2.11.4 but didn't reproduce your issue.

To help us investigate your issue accurately, could you please offer us the following information?
1. Your input Pdf file(if any).
2. Your input certificate file and the password of it.
3. The complete code you were using which could reproduce your issue directly.
4. The OS and Region information, e.g. Win7 64bit, China/Chinese.

You could upload them here or send us(support@e-iceblue.com) via email.

Hi,

Thank you for your inquiry.
The method filepath.getBytes(StandardCharsets.UTF_8) you used to get the certificate data is incorrect. Please change your code as below to load certificate.
Please feel free to contact me if you have any questions.

Code: Select all

      //load from file
      //PdfCertificate digi = new PdfCertificate(filepath,password);
      //load from byte array
      PdfCertificate digi = new PdfCertificate(getFileBytes(pfxPath),password);
      private static byte[] getFileBytes(String file) {
      try {
            File f = new File(file);
            int length = (int) f.length();
            byte[] data = new byte[length];
            new FileInputStream(f).read(data);
            return data;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
