x509certificate2

问题 The Identity provider is encrypting the Saml Assertion using the functions of component pro Dim encryptedSamlAssertion As New EncryptedAssertion(samlAssertion, encryptingCert, New System.Security.Cryptography.Xml.EncryptionMethod(SamlKeyAlgorithm.Aes256Cbc)) At the Service Provider I am trying to Decrypt the assertion. But I cannot use component pro. I have to use System.Security.Cryptography X509Certificate is used for encrypting and decryption Aes256Cbc is the Encryption Algorithm Please

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 We are using ClientCertificate authentication with HttpWebRequest. For the client certificate authentication we are creating the X509Certificate from Pfx file and attached to the outgoing HttpWebRequest. What we see is that after the request is created we are seeing to many temporary files in the folder : C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys As we make more request we see that the number of temporary files created in C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys folder is

问题 We create a X509Certificate2 object in our ASP.NET app to make periodic outgoing connections. Every time one of these certificates is created a new file is created in: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys That folder now has 4 million files that never get cleaned up. I've tried removing the Persist flag new X509Certificate2(certBytes, p12Pwd, X509KeyStorageFlags.MachineKeySet); //no X509KeyStorageFlags.PersistKeySet but that doesn't help -- still get the 2Kb file on every call. I

问题 We are deciding whether "localhost" (and similarly address like "127.0.0.1") should be added as one of the subject alternative names in the certificate. One benefit might be to facilitate local testing. But will there be any drawback? 回答1: Is it a good idea (or bad) to add localhost in Subject Alternative Name? It depends on the standards you follow and your security posture. First things first (for the discussion below). A Fully Qualified Domain Name (FQDN) must be defined. That definition

问题 Facing a really strange issue X509Certificate2.Verify() returning false for a valid certificate. Maybe some has already faced this strange scenario before and can shine some light on it. I am using openssl to generate client certificates for testing purposes. I create a Root CA and generate a client certificate based on that Root CA and add the Root CA to its chain. I load the Root CA and the Client Cert to the local certificate store and it seems ok there but when I load it from my NUnit

问题 I am really trying a long time to use certificates in .NET Core API. Basically where I need to use them is in a .NET Core web api running on IIS and docker. Certificates I need to use are for: Microsoft.AspNetCore.DataProtection public void ConfigureServices(IServiceCollection services) { services.AddDataProtection() .PersistKeysToFileSystem(new DirectoryInfo(dataProtectionKeystorePath)) .ProtectKeysWithCertificate ( new X509Certificate2(dataProtectionCertificatePath,

问题 I have an issue when installing x509 certificate in the system through vb.net. Installation itself is successful, but when I do install it through the code I do get one entry in Certificate Management window as displayed bellow: However when I install it manually using import function in Certificate Management window I do get two entries in the list for this certificate: The problem that I am facing is that when I use this certificate to perform certain tasks (passing some info to the third

问题 We're developing a microservices app on Kubernetes. One of the microservices is IdentityServer instance. Initially, I want to test the solution locally on Docker to make sure it works. For this purpose, I want to copy the certificate to appsettings.json. Eventually this value will be replaced by a Kubernetes secret. In my startup class this is how I'm trying to load my certificate: services.AddIdentityServer() .AddSigningCredential(GetIdentityServerCertificate()) .AddConfigurationStore(...
