Manuel Pégourié-Gonnard da179e4870 Add ecp_curve_list(), hide ecp_supported_curves 2013-09-18 15:37:44 +02:00
Manuel Pégourié-Gonnard 161ef968db Cache pre-computed points for ecp_mul()
Up to 1.25 speedup on ECDSA sign for small curves, but mainly useful as a
preparation for fixed-point mult (a few prototypes changed in constness).

Paul Bakker b6c5d2e1a6 Cleanup up non-prototyped functions (static) and const-correctness
More fixes based on the compiler directives -Wcast-qual -Wwrite-strings
-Wmissing-prototypes -Wmissing-declarations. Not everything with regards
to -Wcast-qual has been fixed as some have unwanted consequences for the
rest of the code.
