 /*----- Revision history --------------------------------------------------* 
  *
  * $Log: hashsum.c,v $
+ * Revision 1.8  2001/04/19 18:26:33  mdw
+ * Add CRC as another hash function.
+ *
+ * Revision 1.7  2001/02/21 20:03:22  mdw
+ * Added support for MD2 hash function.
+ *
+ * Revision 1.6  2001/01/25 21:40:14  mdw
+ * Support for new SHA variants added.
+ *
+ * Revision 1.5  2000/12/06 20:33:27  mdw
+ * Make flags be macros rather than enumerations, to ensure that they're
+ * unsigned.
+ *
+ * Revision 1.4  2000/08/04 23:23:44  mdw
+ * Various <ctype.h> fixes.
+ *
  * Revision 1.3  2000/07/29 17:02:43  mdw
  * (checkhash): Be pettier about spaces between the hash and filename, for
  * compatiblity with `md5sum'.
