title: how to use Microsoft Crypto API with USB Dongle following PKCS#11
body: <p>I have safenet authentication usb token which was given by a company and they told me they have digital public key certificate inside. They gave me a password and a software by which i can see that it can detect certificate inside. Now i need to access this token's certificate and then i need to use signing , encryption and decryption using my development code. But the company didn't gave me any sdk so i have to do everything by C++ Microsoft CryptoAPI. I searched on google but i am not sure if i am on right direction </p>
  
  <p>this code doesn't give me correct handle for the usb stored certificate</p>
  
  <pre><code>        // Attempt to acquire a handle to the default key container.
          bResult = CryptAcquireContext(
                      &amp;hProv,            // Variable to hold returned handle.
                      NULL,              // Use default key container.
                      MS_DEF_PROV,       // Use default CSP.
                      PROV_RSA_FULL,     // Type of provider to acquire.
          0);             
  </code></pre>
  
  <p>i thought it should give any default connected certificate either its on smart card or token.    I tried MS_SCARD_PROV as well in thought if it will give me access through usb token but it seems like its just for the smart card not for token.</p>
  
  <p>I am desperate to complete this task please guide me or show me correct tutorial if you experts know any. Or suggest me what should be done for such kind of task.. </p>
