* 1. Encrypt data.

* 3. Use RSA to unwrap the secret key.
* 4. Decrypt with the newly unwrapped key to get original data.
*
* The first assertion will be the success of RSA to wrap and
* unwrap the secret key.
* The second assertion will be the success of the unwrapped
* key to decrypt the original text.
* Note: Generic secret keys are not used for encrypt/decrypt
* by default. So they will not be included in second
* assertion.
