Signature Information

Get signature information

Use this workflow when you need to inspect who signed a PDF and what signature metadata was stored.

Steps

1. Create a PdfFileSignature instance and bind the signed PDF.
2. Read the signature collection and select a signature name.
3. Call the signature-information accessors for signer name, date, reason, and location.
4. Close the facade object when finished.

Java example

public static void getSignatureInformation(Path inputFile) {
    PdfFileSignature pdfSignature = new PdfFileSignature();
    try {
        pdfSignature.bindPdf(inputFile.toString());
        SignatureName signatureName = pdfSignature.getSignatureNames().get_Item(0);
        System.out.println("Signature Names: " + pdfSignature.getSignNames());
        System.out.println("Signer: " + pdfSignature.getSignerName(signatureName));
        System.out.println("Date: " + pdfSignature.getDateTime(signatureName));
        System.out.println("Reason: " + pdfSignature.getReason(signatureName));
        System.out.println("Location: " + pdfSignature.getLocation(signatureName));
    } finally {
        pdfSignature.close();
    }
}
