x509certificate

问题 I'm new to cryptography and I'm a bit stuck: I'm trying to connect (from my development environment) to a web service using HTTPS. The web service requires a client certificate - which I think I've installed correctly. They have supplied me with a .PFX file. In Windows 7, I double clicked the file to install it into my Current User - Personal certificate store. I then exported a X509 Base-64 encoded .cer file from the certificate entry in the store. It didn't have a private key associate with

问题 I need to get a X509 Certificate by Serial Number, I have the serial number and I am looping through them and i see the serial number in the collection I need but it is never found. Here is my debug code just ot make sure I am seeing the proper serial numbers: X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine); store.Open(OpenFlags.ReadOnly); foreach (X509Certificate2 cert in store.Certificates) { System.Web.HttpContext.Current.Response.Write (cert.SerialNumber + "=" +

问题 I'm trying to load an X509Certificate2 from PEM files in a .NET standard library. I created a self-signed certificate using openssl like so: openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -nodes -subj /CN=localhost -days 365 I loaded the resulting PEM files into embedded string resources within the project and am trying to load them with the following code: private X509Certificate2 GetCertificate() { try { byte[] pubPem = System.Text.Encoding.UTF8.GetBytes(Properties

问题 Question when running the following code: X509Certificate2 cert = new X509Certificate2(@"C:\file.p12", "password", X509KeyStorageFlags.Exportable); RSACryptoServiceProvider crypt = (RSACryptoServiceProvider)cert.PrivateKey; I get the following error: Keyset does not exist . I have not added the certificate to a store, is this required to be able to access the private key? 回答1: Add the X509KeyStorageFlags.PersistKeySet option to the last argument of the X509Certificate2 constructor. Otherwise,

问题 I am building some .net code that will run unattended on a scheduled basis on one of our servers. Part of its execution requires that it execute a Java executable which talks to some web resources and services over SSL. Java will absolutely throw a fit if it's doing something over SSL and it doesn't have every single certificate in the remote certificate's chain. So in .NET I need to be able to specify an https:// resource and need it to download the entire remote chain locally. Why do I want

问题 How can I get a public key certificate deployed to my Worker Role's Trusted People store? I'm using PeerTrust for WCF (self-hosted TCP services in Azure): var creds = new ServiceCredentials(); creds.ClientCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.PeerTrust; I know how to reference the certificate both in my .csdef and in code. However, I don't know how to take a .cer file (with no private key) and actually get it into Azure so it can use it for

问题 I'm attempting to send emails programmatically using SmtpClient.Send . I am currently getting an AuthenticationException when attempting to send the email. This is because of the certificate validation procedure failing. I know that the certificate is the correct one, but I also understand that it's not secure to trust all certificates much like the suggestions of doing this: ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => { return

问题 So below you'll find my code that creates a self signed certificate with the private key in there. It's stored in the user store. Now when I use the mmc tool I can just export the private key from the certificate? I thought that was a flag you had to explicitly add when you create the cert? So what I wanna know is, how do I change this code so that the private key is no longer exportable through mmc. Code: public static X509Certificate2 GenerateSelfSignedCertificateNoCA(string subjectName,

问题 Is there any way we can fetch X509 Public Cetrificates using c# from AD Server for Encrypting an Email. Right now I am using the local Store for Picking up the Certificates and Encrypting an Mail. static public X509Certificate2 GetRecipientCertPublic(string recipientName) { X509Store storeAddressBook = new X509Store(StoreName.AddressBook, StoreLocation.CurrentUser); storeAddressBook.Open(OpenFlags.ReadOnly); X509Certificate2Collection certColl = storeAddressBook.Certificates.Find(X509FindType

问题 I am trying to create a http listener that uses x509 certificates for client/server authentication. My server code is as follows. _listener = new HttpListener(); _listener.Prefixes.Add("https://localhost:8006/"); _listener.Start(); HttpListenerContext context = _listener.GetContext(); My client code is as follows string url = "https://localhost:8006/"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); var store = new X509Store(StoreName.TrustedPeople, StoreLocation.LocalMachine
