Pls hlp....
I don't need to show any logo in signature. But I get "3 miscellaneous
changes" in "modifications list" in Acrobat Reader.
My code of PDFSigner here:
using System;
using System.IO;
using System.Collections;
using org.bouncycastle.pkcs;
using org.bouncycastle.crypto;
using org.bouncycastle.x509;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace PDFSignerNS

{
pk12 = new PKCS12Store(
new FileStream(
pfxFileName,
FileMode.Open,
FileAccess.Read),
pfxPassword.ToCharArray());
IEnumerator i = pk12.aliases();
string alias = "";
while (i.MoveNext())
{
alias = ((string)i.Current);
if (pk12.isKeyEntry(alias))
break;
}
akp = pk12.getKey(alias).getKey();
X509CertificateEntry[] ce = pk12.getCertificateChain (alias);
chain = new X509Certificate[ce.Length];
for (int k = 0; k < ce.Length; ++k)
chain[k] = ce[k].getCertificate();
}
