The problem is CryptHashData() call at provider side. Application calls it with
CRYPT_USERDATA flag and RSAENH provider fails if flags are not zero:

---
RSAENH_CPHashData(...)
---
    if (dwFlags)
    {
        SetLastError(NTE_BAD_FLAGS);
        return FALSE;
    }
---

If this check is removed it no longer crashes, but doesn't do anything useful
either, but after looking at script I think it's intentional.

I'll add some tests for that call first, let's see how it goes. Confirming.
