All that leads me to the thought that I've got get_integral_result wrong; it should take the hash algorithm directly, not its result, and should invoke result() as many times as needed to obtain the necessary number of bits.
This would be incompatible with algorithms that don't support multiple calls to finalize().
That is why multiple calls to result() (there's no finalize) are required to be supported.
Does this mean you're not going to support algorithms that require no more than one call to finalize()/result()? (I'm using finalize() as the name Vinnie has agreed with.) This does not have to be the case, though. You could extend the hash value using some specific algorithm that does support multiple calls to finalize()/result(). It doesn't have to be the same algorithm that produced the original value.
