- * Arguments:  @mp *d@ = destination integer
- *             @mp *r@ = order of the DSA group
- *             @const void *h@ = pointer to message hash
- *             @size_t hsz@ = size (in bytes) of the hash output
- *
- * Returns:    Resulting integer.
- *
- * Use:                Converts a hash to an integer in the demented way necessary
- *             for DSA/ECDSA.  This is, of course, completely insane, but
- *             there you go.
