title: CryptoAPI wrapped keys
body: <p>With CryptoAPI, is there a way to decrypt (<em>using CryptDecrypt</em>) a key written into a SYMMETRICWRAPKEYBLOB?
  In my c++ program, i wrap a symmetric key <em>k1</em> with another symmetric key <em>k2</em> into a symmetric key blob. I have a third key, <em>k3</em>, equal to <em>k2</em> but with a different handle. My goal is to decrypt the blob with this key. I have already did it using a SIMPLEBLOB and a public key.
  Thanks in advance for your attention.
