//! This library implements the CP6_782 curve generated in [[BCGMMW20, “Zexe”]](https://eprint.iacr.org/2018/962).
|
|
//! The name denotes that it was generated using the Cocks--Pinch method for the embedding degree 6.
|
|
//! The main feature of this curve is that the scalar field equals the base field of the BLS12_377 curve.

//!

//! Curve information:
