x509certificate2

I have a .p12 file for my ASP.NET application to connect to a web service via HTTPS. I am trying to import the .p12 file into the Local Machine/My store. The .p12 file contains more than one certificate . One contains the private key and the other is the CA certificate to complete the chain. Currently I am using the `System.Security.Cryptography.X509Certificates.X509Certificate2 object's Import method to import this file into the store. Today I noticed that the CA certificate is not getting imported, only the main certificate containing the private key is getting imported using this method.

I am using smart card for authentication. The SecurityTokenService (authentication service) is hosted on my machine only. The smart card has a valid certificate and it's root certificate is also installed in Local Computer store on my machine. When I use X509Certificate2.Verify method to validate the certificate in my service, it always return false . Can someone help me to understand why X509Certificate2.Verify() method always return false? Note: I used X509Chain and checked for all the flags ( X509VerificationFlags.AllFlags ). When I build the chanin, it returns true with ChainStatus as

Right now, I try instantiating an X509Certificate2 like this: cert = new X509Certificate2(Resources.cred); Where Resources.cred is a byte[] representing a .pfx file. This works absolutely fine on Windows/.NET. However, running the same code under Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-4ubuntu1) (Mono on Ubuntu Server 14.04 LTS), I get the following exception: System.TypeInitializationException: An exception was thrown by the type initializer for <snipped irrelevant type name> ---> System.Security.Cryptography.CryptographicException: Unable to decode certificate. ---> System

I'm developing WCF web service that checks if a certificate in XML signature is valid. XML is signed with qualified and valid X509 certificate. While I am running service within Visual Studio development environment X509Certificate2.Verify() and X509Chain.Build() methods return TRUE. But when I publish my service under IIS these methods return FALSE. What I am doing wrong or what is missing? Here is my validation code: public static void VerifyXml(XmlDocument xDoc) { // Create a new SignedXml object and pass it // the XML document class. SignedXml signedXml = new SignedXml(xDoc); // Find the

Im trying to sign some data using PKCS#12 certificate ,however i have problem with obtaining private key from PKCS#12 (.p12) file. public byte[] sign(string text) { string password = "1111"; X509Certificate2 cert = new X509Certificate2("c:\\certificate.p12",password); byte[] certData = cert.Export(X509ContentType.Pfx,password); X509Certificate2 newCert = new X509Certificate2(certData, password); RSACryptoServiceProvider crypt = (RSACryptoServiceProvider)newCert.PrivateKey; SHA1Managed sha1 = new SHA1Managed(); UnicodeEncoding encoding = new UnicodeEncoding(); byte[] data = encoding.GetBytes
