    Before calling CryptGenKey you can prompt for the password yourself and send
    it to the CSP via CryptSetProvParam with PP_KEYEXCHANGE_PIN or
    PP_SIGNATURE_PIN (depending on what type of keypair you are generating).
    Note that this behavior is CSP dependent so in some CSPs may not support it.
