x509certificate2

I'm using the Google Analytics API and I followed this SO question to set up the OAuth: https://stackoverflow.com/a/13013265/1299363 Here is my OAuth code: public void SetupOAuth () { var Cert = new X509Certificate2( PrivateKeyPath, "notasecret", X509KeyStorageFlags.Exportable); var Provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, Cert) { ServiceAccountId = ServiceAccountUser, Scope = ApiUrl + "analytics.readonly" }; var Auth = new OAuth2Authenticator<AssertionFlowClient>(Provider, AssertionFlowClient.GetState); Service = new AnalyticsService(Auth); } PrivateKeyPath

I'm trying to use an OpenSSL code in my .Net program. Here's the code: openssl pkcs12 -in "My PassKit Cert.p12" -clcerts -nokeys -out certificate.pem openssl pkcs12 -in "My PassKit Cert.p12" -nocerts -out key.pem smime -binary -sign -signer certificate.pem -inkey key.pem -in manifest.json -out signature -outform DER I tried to use .Net OpenSSL, but I absolutely have no idea how to use it, and I couldn't find a good documentation for it. I decided to use .Net to perform the same sign process, here's the code: var dataToSign = System.IO.File.ReadAllBytes(filePathToSign); ContentInfo contentInfo

Today, a colleague hit yet another bug related to these! I've found these flags really frustrating in past myself, because if you get them slightly wrong while instantiating X509Certificate2 objects, or exporting them, or saving them in an X509Store you can land in situations with all sorts of weird bugs such as: unexpectedly can't tell NETSH.exe or ASP.net to use a certain SSL certificate [by its thumbprint], even though you have that cert in your machine store unexpectedly you can export the cert data but it gets exported without the private key using .Export() unexpectedly your unit tests

I am trying to export a cert without the private key as as BASE-64 encoded file, same as exporting it from windows. When exported from windows I am able to open the .cer file in notepad. When I try the following and open on notepad I get binary data...I think it is...not readable. X509Certificate2 cert = new X509Certificate2("c:\\myCert.pfx", "test", X509KeyStorageFlags.Exportable); File.WriteAllBytes("c:\\testcer.cer", cert.Export(X509ContentType.Cert)); I tried removing the 'X509KeyStorageFlags.Exportable" but that doesn't work. Am I missing something? Edit - I tried File.WriteAllText("c:\

I have site in Azure Websites (not Hosted Service) and I need processing .pfx certificates with private key there. var x509Certificate2 = new X509Certificate2(certificate, password); But I was faced with follow exception: System.Security.Cryptography.CryptographicException: The system cannot find the file specified. at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr) at System.Security.Cryptography.X509Certificates.X509Utils._LoadCertFromBlob(Byte[] rawData, IntPtr password, UInt32 dwFlags, Boolean persistKeySet, SafeCertContextHandle& pCertCtx) at

I'm trying to construct an X509Certificate2 from a PKCS#12 blob in a byte array and getting a rather puzzling error. This code is running in a desktop application with administrator rights on Windows XP. The stack trace is as follows, but I got lost trying to troubleshoot because _LoadCertFromBlob is marked [MethodImpl(MethodImplOptions.InternalCall)] . System.Security.Cryptography.CryptographicException: The system cannot find the file specified. at System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException(Int32 hr) at System.Security.Cryptography.X509Certificates

is there any convenient way to export private/public keys from .p12 certificate in PEM format using .NET Core ? Without manipulating with bytes at low level? I googled for hours and almost nothing is usable in .net core or it isn't documented anywhere.. Let's have an X509Certificate2 var cert = new X509Certificate2(someBytes, pass); var privateKey = cert.GetRSAPrivateKey(); var publicKey = cert.GetRSAPublicKey(); // assume everything is fine so far And now I need to export the keys as two separate PEM keys. I already tried PemWriter in BouncyCastle but the types are not compatibile with System

I am trying to programmatically import a X509 certificate (pfx / PKCS#12) in my local machine's certificate store. This particular certificate has a chain of certificates, the certification path looks something like this: Root certificate CA Organization certificate CA Organization 2 certificate CA My certificate The code I use looks like this: cert = new X509Certificate2(pathToCert, password); if (cert != null) { var store = new X509Store(StoreName.My, StoreLocation.LocalMachine); store.Open(OpenFlags.ReadWrite); if (!store.Certificates.Contains(cert)) { store.Add(cert); } } This code does
