How to read a private key from pvk file in C#?

Question

I have to read a private key, and this key is on pvk format. I use X509Certificate2 class, but i this class i have only public key access. How can I get a private key from pvk file?

@Luis, I am struggling with the same at the moment. Did you figure out how to get the private key from a .pvk file? — Rashmi Pandit, Feb 10 '15 at 23:04

Luiz, you need to combine the CER and PVK into a single PFX file, then import the file as a cert so that when you load the X509Cert the PrivateKey will be there. See Decrypt with PrivateKey X.509 Certificate.

You can use this command to combine them.

pvk2pfx -spc CA.cer -pvk CA.pvk -pfx CA.pfx

How about this ?

Have in mind:

Currently this property supports only RSA or DSA keys, so it returns either an RSACryptoServiceProvider or a DSACryptoServiceProvider object. If no private key is associated with the certificate, a null reference (Nothing in Visual Basic) is returned

This doesn't address the question. The link shows how to read the PrivateKey from an X509Cert if it's already present, but not how to load it from a pvk file. – Peter Oct 11 '12 at 02:38
