This module implements the BW6_767 curve generated by [El Housni and Guillevic], using their generic approach described in [HG21]. The name denotes that it is a curve generated using the Brezing--Weng method, and that its embedding degree is 6. The main feature of this curve is that the scalar field equals the base field of the BLS12_381 curve.

Curve information:

  • Base field: q = 496597749679620867773432037469214230242402307330180853437434581099336634619713640485778675608223760166307530047354464605410050411581079376994803852937842168733702867087556948851016246640584660942486895230518034810309227309966899431
