BLS12-377 (#91) 
* add Sage for constant time tonelli shanks

* Fused sqrt and invsqrt via Tonelli Shanks

* isolate sqrt in their own folder

* Implement constant-time Tonelli Shanks for any prime

* Implement Fp2 sqrt for any non-residue

* Add tests for BLS12_377

* Lattice decomposition script for BLS12_377 G1

* BLS12-377 G1 GLV ok, G2 GLV issue

* Proper endomorphism acceleration support for BLS12-377

* Add naive pairing support for BLS12-377

* Activate more bench for BLS12-377

* Fix MSB computation

* Optimize final exponentiation + add benches

Sage scripts

This folder holds sage scripts:

  • either for automating curve configuration for example for computing the prime and order of BN or BLS curve families, for irreducible polynomials for extension fields.
  • for test vectors against a reference implementation.
