Thanks Paulo for your quick response. At the end the code leaves as follow,
Public Function GetChain(ByVal cer As Certificate) As
System.Security.Cryptography.X509Certificates.X509Certificate()
Dim context As ICertContext = CType(cer, ICertContext)
Dim ptr As IntPtr = New IntPtr(context.CertContext)
Dim xCert As
System.Security.Cryptography.X509Certificates.X509Certificate = New
System.Security.Cryptography.X509Certificates.X509Certificate(ptr)
Dim cp As Org.BouncyCastle.X509.X509CertificateParser = New
Org.BouncyCastle.X509.X509CertificateParser
Dim chain() As
System.Security.Cryptography.X509Certificates.X509Certificate = New
System.Security.Cryptography.X509Certificates.X509Certificate()
{cp.ReadCertificates(xCert.GetRawCertData)}
'.ReadCertificate(xCert.GetRawCertData())
Return chain
End Function
This is ok. But in the main function the IDE says me that chains must be
from Org.BouncyCastle.X509.X509Certificate in the lines,
sap.SetCrypto(Nothing, chain, Nothing, Nothing),
dic.Name = PdfPKCS7.GetSubjectFields(chain(0)).GetField("CN").
What is going wrong?
Thanks again,
Jose Alvarez de Lara
