David Núñez c394e72e7c Change CurveBN.expected_bytes_length to use the curve group order size 2018-08-06 20:29:04 -05:00
David Núñez b84c83ed44 Introduce curve.group_order_size_in_bytes (different from field order) 2018-08-06 20:29:04 -05:00
David Núñez 1a47ce8493 Use number of bytes returned by BN_bn2bin as ffi.buffer size 
The problem is that ffi.buffer fills memory "justified to the left", so e.g., if the BN is 1, the buffer is 010000....00, and we want 00...000001
