Hello, I'm having an error trying to use the ITSAClient. I've
used a lot of diferent url to get the timestamp but no one works. I don't know
what I'm doing wrong or where is the mistake.
My code is:
public static void signPdfFile(string sourceDocument, string
destinationPath, SysX509.X509Certificate2 signature, string keyPassword, string
reason, string location, bool AddVisibleSign, int Pagina, int IzquierdaX, int
IzquierdaY, int DerechaX,int DerechaY, string Contact, bool MultiSinght)
{
//X509Certificate2 signature = null;//Your X509Certificate2
certificate instance here.
string a = signature.PrivateKey.ToString();
var akp =
Org.BouncyCastle.Security.DotNetUtilities.GetKeyPair(signature.PrivateKey).Private;
IExternalSignature es = new PrivateKeySignature(akp, "SHA-256");
// reader and stamper
PdfReader reader = new PdfReader(sourceDocument);
using (FileStream fout = new FileStream(destinationPath,
FileMode.Create, FileAccess.ReadWrite))
{
using (PdfStamper stamper = PdfStamper.CreateSignature(reader,
fout, '\0', null, MultiSinght))
{
// appearance
PdfSignatureAppearance appearance =
stamper.SignatureAppearance;
//appearance.Image = new iTextSharp.text.pdf.PdfImage();
if (reason != "") appearance.Reason = reason;
if (location != "") appearance.Location = location;
if (Contact != "") appearance.Contact = Contact;
if (AddVisibleSign)
appearance.SetVisibleSignature(new
Rectangle(IzquierdaX, IzquierdaY, DerechaX, DerechaY), Pagina, null);
// digital signature
Org.BouncyCastle.X509.X509CertificateParser cp = new
Org.BouncyCastle.X509.X509CertificateParser();
Org.BouncyCastle.X509.X509Certificate[] chain = new[] {
cp.ReadCertificate(signature.RawData) };
//string TSA_URL =
"http://timestamp.globalsign.com/scripts/timstamp.dll";;
//String TSA_URL = "http://tsatest1.digistamp.com/TSA";;
String TSA_URL =
"http://timestamp.verisign.com/scripts/timstamp.dll";; //Con este optengo algo
válido
//String TSA_URL =
"http://www.trustcenter.de/codesigning/timestamp";; //Con este optengo algo
válido
//String TSA_URL =
"http://timestamp.comodoca.com/authenticode";//Optengo algo pero no en el
formato correcto.
//String TSA_URL =
"http://www.edelweb.fr/cgi-bin/service-tsp";;
//String TSA_URL =
"http://dse200.ncipher.com/TSS/HttpTspServer";;
//String TSA_URL = "http://tsa.safelayer.com:8093";;
//string TSA_URL = "http://www.cryptopro.ru/tsp/tsp.srf";;
ITSAClient TsaCliente = new TSAClientBouncyCastle(TSA_URL);
MakeSignature.SignDetached(appearance, es, chain, null,
null, TsaCliente, 0, CryptoStandard.CMS);
stamper.Close();
}
}
}
I get the error:
