* include the coefficients of bls12-377 G1 and G2 isogenies for wb hash2curve * replacing the ark-ec dependency to w3f/arkworks-algebra * added parameters for isogenous curve to bls12-377 g1 curve for swu map * fix dependency inconsistency problem * implement WBParams and its isogenous curve for BLS12-377 G1 * implement the SWUParameters for isogenous curve to BLS12-377 g2 curve. * implement WBParams for BLS12-377 G2 curve * replacing const generic arrays with const slice in g1 and g2 iso coefficients * - Implement WB hash to curve for BLS12-381 G1 - Improvement to WB hash to curve code for BLS12-377 - Update sage code for generating isogeny coefficients for arkworks. * Implement WB hash to curve for BLS12-381 G2 * - fix the bug with base order for field_new for Fq2 - fix the polynomial coeffcient order for bls12-381 g1 and g2 isogenies. - fix the polynomial coeffcient order for bls12-377 g1. 377-g2 needs to be fixed still. * fix bls12-377 wb hash to curve isogeny coeffcients * fixed sage code for generating the isogeny coefficients * use patch.crates-io hack to resolve dependancy issues on w3f fork * Rename `Parameters` to `Config` for all fields * Rename `field_new` to `MontFp` * Rename `field_new` to `QuadExt` and `CubicExt` * Refactor bls12_381 crate based on update-ff branch. Close #9 * adapt bls12 wb hashing to new changes in algebra * update bls12-381 dependancies and g1, g2 definition to pass tests * adapt bls12-377 hash to curve to algebar updates * depend on upstream for pull request * cargo fmt * - move the isogeny finder script from sage to script folder - delete auxiliary isogeny coeff file * add unit tests for wb hashing to bls12-377 g1 and g2 * - Use IsogenyMap struct to specify WB Isogeny for bls12-381 and bls12-377 - Do not use auxiliary constants to define generators of g2_swu_iso curve. - Update change log * Bump the Algebra dependencies of bls12_381 and bls12_377 to 0.4.0-alpha.4 so they could use the IsogenyMap struct. * Add h2c tests for BLS12-381 curve * Drop alpha sub-version in dependancies because it takes the lastest sub version * Parameters → Config for bls12-377/381 curves * do cargo fmt * do SwuIsoParameters → SwuIsoConfig for bls12-377/381 * Adapt to new macro * Fix macro invocation should be semicolon not comma * curves master should use algebra/r1cs default branch * Add h2c test invocation for bls12-377 curve no actual test vectors yet * add faster cofactor clearing and tests for g1 * add faster cofactor clearing and tests for g2 parameters of endomorphisms are wrong for now * add test vectors for bls12-377 * add h_eff to g2 tests for correctness test * improve cofactor tests g2 * add a test for psi(psi(P)) == psi2(P) * fix bls12-377 psi & psi2 computation parameters * rename const to DOUBLE_P_POWER_ENDOMORPHISM_COEFF_0 and make private * fix clippy warnings in changed code * use the same zeta as test suites * update code comments, make methods private * update changelog Co-authored-by: Pratyush Mishra <pratyushmishra@berkeley.edu> Co-authored-by: mmagician <marcin.gorny.94@protonmail.com>
