- * $Log: mpbarrett.c,v $
- * Revision 1.9 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 1.8 2001/06/16 13:00:20 mdw
- * Use the generic exponentiation functions.
- *
- * Revision 1.7 2001/04/19 18:25:26 mdw
- * Use sliding-window exponentiation.
- *
- * Revision 1.6 2000/10/08 12:03:44 mdw
- * (mpbarrett_reduce): Cope with negative numbers.
- *
- * Revision 1.5 2000/07/29 17:04:33 mdw
- * Change to use left-to-right bitwise exponentiation. This will improve
- * performance when the base is small.
- *
- * Revision 1.4 2000/06/17 11:45:09 mdw
- * Major memory management overhaul. Added arena support. Use the secure
- * arena for secret integers. Replace and improve the MP management macros
- * (e.g., replace MP_MODIFY by MP_DEST).
- *
- * Revision 1.3 1999/12/12 15:08:52 mdw
- * Don't bother shifting %$q$% in @mpbarrett_reduce@, just skip the least
- * significant digits.
- *
- * Revision 1.2 1999/12/11 01:50:56 mdw
- * Improve initialization slightly.
- *
- * Revision 1.1 1999/12/10 23:21:59 mdw
- * Barrett reduction support: works with even moduli.
