+ * Revision 1.3 2000/07/02 18:27:42 mdw
+ * (ghash->ops->done): Interface change. Passing in a null buffer pointer
+ * uses a buffer internal to the ghash object. The operation returns the
+ * address of the buffer it used. Clients of generic hashes no longer need
+ * to use dynamically allocated memory for hash results.
+ *
* Revision 1.2 2000/06/17 11:22:03 mdw
* Use secure arena for memory allocation. Minor changes in the generic
* hash interface.
