Dear Team, I changed the filling of "kall" in the code I went through in all "StoreName" of all "StoreLocation" thus I think I collected all certificate into the "kall". Then I debuged what happening there and I found that the verified certificate's SerialNumer is 7 in pkc[0] but the SerialNumer is 8 in kall[50] and the all other properties are the same.
Why the serialnumbers are differents, can anybody help to me? Why is good for Acrobat Reader ? Attila. NEW CODE: --------- public virtual void Verify(Stream inStream) { List<X509Certificate> kall = new List<X509Certificate>(); foreach (System.Security.Cryptography.X509Certificates.StoreLocation storeLocation in typeof(System.Security.Cryptography.X509Certificates.StoreLocation).GetEnumValues()) { foreach (System.Security.Cryptography.X509Certificates.StoreName storeName in typeof(System.Security.Cryptography.X509Certificates.StoreName).GetEnumValues()) { System.Security.Cryptography.X509Certificates.X509Store store = new System.Security.Cryptography.X509Certificates.X509Store(storeName, storeLocation); store.Open(System.Security.Cryptography.X509Certificates.OpenFlags.ReadOnly); try { X509CertificateParser certParser = new X509CertificateParser(); System.Security.Cryptography.X509Certificates.X509Certificate2Collection col = store.Certificates; foreach (System.Security.Cryptography.X509Certificates.X509Certificate2 cer in col) { kall.Add(certParser.ReadCertificate(cer.RawData)); } } finally { store.Close(); } } } ... } ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.
