used is always the default library context.
EC_GROUP_set_curve() sets the curve parameters B<p>, B<a> and B<b>. For a curve
over Fp B<b> is the prime for the field. For a curve over F2^m B<p> represents
over Fp B<p> is the prime for the field. For a curve over F2^m B<p> represents
the irreducible polynomial - each bit represents a term in the polynomial.
Therefore there will either be three or five bits set dependent on whether the
polynomial is a trinomial or a pentanomial.
In either case, B<a> and B<b> represents the coefficients a and b from the
relevant equation introduced above.
EC_group_get_curve() obtains the previously set curve parameters.
