- *
- * $Log: dh.h,v $
- * Revision 1.8  2004/04/01 12:50:09  mdw
- * Add cyclic group abstraction, with test code.  Separate off exponentation
- * functions for better static linking.  Fix a buttload of bugs on the way.
- * Generally ensure that negative exponents do inversion correctly.  Add
- * table of standard prime-field subgroups.  (Binary field subgroups are
- * currently unimplemented but easy to add if anyone ever finds a good one.)
- *
- * Revision 1.7  2001/02/03 16:08:24  mdw
- * Add consistency checking for public keys.
- *
- * Revision 1.6  2000/07/29 10:01:16  mdw
- * Supply commentry for the Diffie-Hellman parameters.  Add Lim-Lee
- * parameter generation.
- *
- * Revision 1.5  2000/07/01 11:20:51  mdw
- * New functions for freeing public and private keys.
- *
- * Revision 1.4  2000/06/17 10:52:47  mdw
- * Minor changes for key fetching.
- *
- * Revision 1.3  2000/02/12 18:21:02  mdw
- * Overhaul of key management (again).
