* Point decoding: optimized sqrt for p ≡ 5 (mod 8) (Curve25519)
* Implement fused sqrt(u/v) for twisted edwards point deserialization
* Introduce twisted edwards affine
* Allow declaration of curve field elements (and fight against recursive dependencies
* Twisted edwards group law + tests
* Add support for jubjub and bandersnatch #162
* test twisted edwards scalar mul
* Add Fp, Fp2, Fp6 support for BW6-761
* Add G1 for BW6-761
* Prepare to support G2 twists on the same field as G1
* Remove a useless dependent type for lines
* Implement G2 for BW6-761
* Fix Line leftover
* 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
* Pairing - initial commit
- line functions
- sparse Fp12 functions
* Small fixes:
- Line parametrized by twist for generic algorithm
- Add a conjugate operator for quadratic extensions
- Have frobenius use it
- Create an Affine coordinate type for elliptic curve
* Implement (failing) pairing test
* Stash pairing debug session, temp switch Fp12 over Fp4
* Proper naive pairing on BLS12-381
* Frobenius map
* Implement naive pairing for BN curves
* Add pairing tests to CI + reduce time spent on lower-level tests
* Test without assembler in Github Actions + less base layers test iterations
The running time of the test suite has increased significantly with:
- new tests (for example scalar mul implementations)
- new tests that stresses the whole stack/tower
- x3 randomizers for fuzzing
- new CI and platforms: Total 16x runs per commit
This would let all tests take less than 10 min on CI even non-parallelized one like on Windows.
* Add test case for #30 - Euler's criterion doesn't return 1 for a square
* Detect #42 in the test suite
* Detect #43 in the test suite
* comment in sqrt tests
* Add #67 to the anti-regression suite
* Add #61 to the anti-regression suite
* Add #62 to anti-regression suite
* Add #60 to the anti-regression suite
* Add #64 to the test suite
* Add #65 - case 1
* Add #65 case 2
* Add #65 case 3
* Add debug check to isSquare/Euler's Criterion/Legendre Symbol
* Make sure our primitives are correct
* For now deactivate montySquare CIOS fix#61#62
* Narrow down #42 and #43 to powinv on 32-bit
* Detect #42#43 at the fast squaring level
* More #42, #43 tests, Use multiplication instead of squaring as a temporary workaround, see https://github.com/mratsim/constantine/issues/68
* Prevent regression of #67 now that squaring is "fixed"
