+ * Revision 1.5 2001/01/25 21:39:58 mdw
+ * Burn the hash context when it's done with, for paranoia's sake.
+ *
+ * Revision 1.4 2000/07/15 10:00:58 mdw
+ * New generic hash operation for copying hash contexts.
+ *
+ * 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.
