Back
I following this example:
http://article.gmane.org/gmane.comp.windows.dotnet.itextsharp.general/12
I export the X509Certificate2 to byte[] and import into a PKCS12Store
object, with MemoryStream, and into a bouncycastles X509Certificate object:
<CODE>
cert = new
org.bouncycastle.x509.X509Certificate(Certificado.Export(X509ContentType.Cer
t));
PKCS12Store p12 = new PKCS12Store(new
MemoryStream(Certificado.Export(X509ContentType.Pkcs12)), "".ToCharArray());
string alias = p12.getCertificateAlias(cert);
</CODE>
The string alias is null, the sign function finally successfully, but the
output pdf have 0kb.

You get your X509Certificate2, export it to a byte array and create a new
bouncycastle certificate with it.
