   2  * Attribution notice: Rainbow have generously allowed me to reproduce the
   3  * necessary definitions here from their API. This means the support can
   4  * build independently of whether application builders have the API or
   5  * hardware. This will allow developers to easily produce software that has
   6  * latent hardware support for any users that have accelertors installed,
   7  * without the developers themselves needing anything extra. I have only
   8  * clipped the parts from the CryptoSwift header files that are (or seem)
   9  * relevant to the CryptoSwift support code. This is simply to keep the file
  10  * sizes reasonable. [Geoff]

  14  * NB: These type widths do *not* seem right in general, in particular
  15  * they're not terribly friendly to 64-bit architectures (unsigned long) will
  16  * be 64-bit on IA-64 for a start. I'm leaving these alone as they agree with
  17  * Rainbow's API and this will only be called into question on platforms with
  18  * Rainbow support anyway! ;-)
