Thank you!!!
Fionn
My Code:
public static byte[] getBytesFromDocumentToSign(File aSourcePdfFile)
throws
IOException
{
byte[] tOriginalBytes = null;
PdfReader tReader = new
PdfReader(aSourcePdfFile.getAbsolutePath());
AcroFields tFields = tReader.getAcroFields();
if (tFields.getSignatureNames().size() < 1) { throw new
IOException(
"Wrong file: no signature found in document:" +
aSourcePdfFile.getAbsolutePath()); }
String tSig = (String) tFields.getSignatureNames().get(0);
PdfDictionary tDic = tFields.getSignatureDictionary(tSig);
PdfString tContents = (PdfString)
PdfReader.getPdfObject(tDic.get(PdfName.CONTENTS));
//System.out.println(tContents);
tOriginalBytes = tContents.getOriginalBytes();
return tOriginalBytes;
}
