/*----- Revision history --------------------------------------------------*
*
* $Log: rspit.c,v $
+ * Revision 1.16 2001/04/29 18:11:32 mdw
+ * New block ciphers.
+ *
+ * Revision 1.15 2001/04/19 18:26:13 mdw
+ * Use the new MAC keysize names.
+ *
+ * Revision 1.14 2001/02/21 20:03:22 mdw
+ * Added support for MD2 hash function.
+ *
+ * Revision 1.13 2000/12/06 20:33:27 mdw
+ * Make flags be macros rather than enumerations, to ensure that they're
+ * unsigned.
+ *
+ * Revision 1.12 2000/10/08 15:49:18 mdw
+ * Remove failed kludge for shutting up a warning.
+ *
+ * Revision 1.11 2000/10/08 12:10:32 mdw
+ * Make table have external linkage to bodge around deficiency in C. The
+ * problem is that @static gen generators[];@ is considered to be a
+ * `tentative definition', and therefore mustn't have incomplete type,
+ * which it obviously has.
+ *
+ * Revision 1.10 2000/08/11 21:34:59 mdw
+ * New restartable interface to Maurer testing.
+ *
* Revision 1.9 2000/08/04 23:24:15 mdw
* Add a timer and a discard option.
