When invoking the RSA encrypted. PFX key, there is no problem with local debugging, and the following error is reported when the server is ready for deployment:

The user code did not process System.Security.Cryptography.CryptographicException hresult=-2146893792 message= An internal error occurred.

Processing method:

IIS Application Pool--Select the configured application pool for your site--right-click on Advanced Configuration--Set load user profile to True. Problem solving

3. If none of the above two scenarios solve the problem, it is possible that the certificate was not given a certificate store identity when it was loaded

Workaround: Use the following method when loading the certificate method, note the third parameter

X509Certificate2 cer = new X509Certificate2 (cerpath, password, x509keystorageflags.machinekeyset | X509keystorageflags.persistkeyset | X509keystorageflags.exportable);
Req. Clientcertificates.add (CER);
