I now have this working:
string alias = null;
PKCS12Store pk12 = new PKCS12Store(new
FileStream(@"D:\Work\Projekter\DubliNet\Sikkerhed\Certifikatet\PrivateKeyWithCert.p12",
FileMode.Open, FileAccess.Read), "TooHot4u".ToCharArray());
IEnumerator i = pk12.aliases();
while (i.MoveNext())
{
alias = ((string)i.Current);
if (pk12.isKeyEntry(alias))
break;
}
AsymmetricKeyParameter akp = pk12.getKey(alias).getKey();
X509CertificateEntry[] ce = pk12.getCertificateChain(alias);
X509Certificate[] chain = new X509Certificate[ce.Length];
for (int k = 0; k < ce.Length; ++k)
chain[k] = ce[k].getCertificate();
PdfReader reader = new
PdfReader(@"D:\Work\Projekter\DubliNet\Blanketter\20050104 InfoRequest filled
out.pdf");
PdfStamper st = PdfStamper.CreateSignature(reader, new
FileStream(@"D:\Work\Projekter\DubliNet\Blanketter\20050104 InfoRequest
filled out SIGNED.pdf", FileMode.Create, FileAccess.Write), '\0');
PdfSignatureAppearance sap = st.SignatureAppearance;
sap.SetCrypto(akp, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
sap.Reason = "I am approving this document";
sap.Location = "Denmark";
sap.SetVisibleSignature(new iTextSharp.text.Rectangle(50, 75, 250, 150), 1,
null);
st.Close();
But once the document has been signed, a user can still edit the form. I need
this to be disabled. How can I do that?
And what are the WINCER_SIGNED, SELF_SIGNED and VERISIGN_SIGNED options?
Thanks in advance.
Med venlig hilsen

Subject: RE: [iText-questions] Signing a PDF file with a digital signature
Hi
Using this code:
X509CertificateParser p = new X509CertificateParser(new
FileStream(@"D:\Work\Projekter\DubliNet\Sikkerhed\Certifikatet\PrivateKey.p12",
FileMode.Open, FileAccess.Read)); X509Certificate x = p.ReadCertificate();
I get a System.ArgumentException in the second line. Aditional information:
unknown object in factory
Using this code:
string alias = null;
PKCS12Store pk12 = new PKCS12Store(new
FileStream(@"D:\Work\Projekter\DubliNet\Sikkerhed\Certifikatet\PrivateKey.p12",
FileMode.Open, FileAccess.Read), "TooHot4u".ToCharArray()); IEnumerator
i = pk12.aliases(); while (i.MoveNext()) {
alias = ((string)i.Current);
if (pk12.isKeyEntry(alias))
break;
}
AsymmetricKeyParameter akp = pk12.getKey(alias).getKey();
I get an InvalidCastException in the last line. Additional information:
Specified cast is not valid. The "pk12.isKeyEntry(alias) returns true on the
first iteration on i.
Med venlig hilsen

What error do you get and in what part of the code?
