x509certificate

I am trying to consume a Web Service HTTPS (using a certificate authentication). I have added my Web Service in my Web Reference on my project and "myCertificate.cer" has imported to Console Root\Certificates\Personal. I have an error 401: The request failed with HTTP status 401: Unauthorized. Any idea? .... using System.Security.Cryptography.X509Certificates; ... string certPath = @"C:\myCertificate.cer"; // Load the certificate into an X509Certificate object. X509Certificate cert = X509Certificate.CreateFromCertFile(certPath); // Create an instance of the Web service proxy. zgetuser

Can anyone translate these two cryptui.dll functions/structures into C#.NET [dllimport] wrappers? I would like to P/Invoke the CryptUIWizExport function to display the Windows Certificate Export Wizard. In particular, I need to pass a .NET X509Certificate as a parameter into the CryptUIWizExport function. You help is much appreciated!!! CryptUIWizExport function BOOL WINAPI CryptUIWizExport( __in DWORD dwFlags, __in HWND hwndParent, __in LPCWSTR pwszWizardTitle, __in PCCRYPTUI_WIZ_EXPORT_INFO pExportInfo, __in void *pvoid ); typedef struct _CRYPTUI_WIZ_EXPORT_INFO { DWORD dwSize; LPCWSTR

We have developed a webbased Java application running in Tomcat under IIS on Windows 2008. The website has 2-way (mutual) SSL enabled in IIS requiring the client to authenticate using a x.509 certificate (PKI) as part of SSL and this works fine with all our certificates using IE. The website also has a java-applet called ViewOne ImageViewer. This works fine with 2-way SSL with some of our certificates but with others we get the exception on the client (java 1.6) during SSL-handshake after the user has selected its authentication certificate: security: KeyUsage does not allow digital signatures

I need to create a RSAParameters object in .Net using a private and public key (.key and .cer file). Is it possible to do this in .Net without the use of third party software? If so, where should I be looking. I ultimately need to extract the Exponent, Modulus, D, P, Q, DP, DQ, InverseQ from this object in order to create a keyblob for a cryptoServer. Thanks! ".key" and ".cer" file extensions are in no way an unambiguous specification of how the keys are encoded. However, it is plausible that the ".cer" file is an X.509 certificate, which contains (among many other things) the public key;

Our use-case requires validating certificate revocation via OCSP on a PKIX set-up. My starting point was the code at this related question: OCSP Revocation on client certificate I'm doing it manually at the application level since tomcat doesn't support it. However, I'm having some trouble building the certPath and I think I'm missing some fundamental understanding. First I try to create the certPath for the incoming client x509Certificate. KeyStore store is initialized correctly and contains only the root certificates that match the client x509Certificate. EDIT: I got the same result after
