Thanks for your quick answer :)
How could I know the security settings?
Because I create all my different pdf in Adobe Designer without changing
settings :(
So it's for that I don't understand the difference!!!

Bonjour Michael,
Your different PDF files may have different security setting in which signing
is not allowed.

Subject: [iText-questions] Question about Itext library and pdf signature
Hi,
I use your library Itext in a project to sign pdf file.
I try to follow the code example that I saw on your website but I have a
problem.
This is my java code :
try{
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(new FileInputStream("keystore.ks"),
"pdfpassword".toCharArray());
PrivateKey key = (PrivateKey)ks.getKey("pdf",
"pdfpassword".toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);
for (int i = 0; i < pdfFilenames.length; i++) {
PdfReader reader = new PdfReader(pdfFilenames[i]);
//on enleve l'extension du nom de fichier à traiter
afin de modifier le nom
String name = pdfFilenames[i].substring(0,
pdfFilenames[i].lastIndexOf('.'));
FileOutputStream fout = new
FileOutputStream(name+"_signed.pdf");
PdfStamper stp = PdfStamper.createSignature(reader,
fout, '\0');
PdfSignatureAppearance sap =
stp.getSignatureAppearance();
sap.setCrypto(key, chain, null,
PdfSignatureAppearance.SELF_SIGNED);
sap.setCertificationLevel(PdfSignatureAppearance.CERTIFIED_FORM_FILLING);
//comment next line to have an invisible signature
sap.setVisibleSignature(new Rectangle(100, 100, 200,
200), 1, null);
stp.close();
}
}catch(Exception e){
e.printStackTrace();
}
There is no error during the execution.
But I don't see a difference between the first pdf and the pdf signed each time.
In fact, I make different tests.
I use 5 different pdf as input file. At the output only two pdf contain a
signature (although the signature is different in these two cases).
So I don't understand why the signature doesn't work in every case.
If you can help me, it will be great.
Thanks
Best regards,
