NOTE: current ecdsa requires `r, s` to be given as proper CRT integers TODO: newtypes to guard this assumption
2 embarassing errors: * Witness gen for last bit was wrong (used xor instead of &) * `ctx.get` was called after `range_check` so it was getting the wrong cell
feat: add documentation for all debug_asserts
Add `divide` that checks denomintor is nonzero. Add documentation in cases where `divide_unsafe` is used.
* feat: add new types `ProperUint` and `ProperCrtUint` To guard around assumptions about big integer representations * fix: remove unused `FixedAssignedCRTInteger` * feat: use new types for bigint and field chips New types now guard for different assumptions on non-native bigint arithmetic. Distinguish between: - Overflow CRT integers - Proper BigUint with native part derived from limbs - Field elements where inequality < modulus is checked Also add type to help guard for inequality check in ec_add_unequal_strict Rust traits did not play so nicely with references, so I had to switch many functions to move inputs instead of borrow by reference. However to avoid writing `clone` everywhere, we allow conversion `From` reference to the new type via cloning. * feat: use `ProperUint` for `big_less_than` * feat(ecc): add fns for assign private witness points that constrain point to lie on curve * fix: unnecessary lifetimes * chore: remove clones
* feat: allow `msm_par` to return identity point * feat: handle point at infinity `multi_scalar_multiply` and `multi_exp_par` now handle point at infinity completely Add docs for `ec_add_unequal, ec_sub_unequal, ec_double_and_add_unequal` to specify point at infinity leads to undefined behavior
* `msm` implementations now always use `ec_{add,sub}_unequal` in strict
mode for safety
* Add docs to `scalar_multiply` and a flag to specify when it's safe to
turn off some strict assumptions
Multi-threading of witness generation is tricky because one has to ensure the circuit column assignment order stays deterministic. To ensure good developer experience / avoiding pitfalls, we provide a new helper function for this. Co-authored-by: Jonathan Wang <jonathanpwang@users.noreply.github.com>
We still require fixed base points to be non-identity, but now handle the case when scalars may be zero or the final MSM value is identity point.
* More ecdsa tests * Update mod.rs * Update tests.rs * Update ecdsa.rs * Update ecdsa.rs * Update ecdsa.rs * chore: sync with release-0.3.0 and update CI Co-authored-by: yulliakot <yulliakotel@gmail.com> Co-authored-by: yuliakot <93175658+yuliakot@users.noreply.github.com>
cannot multi-thread tests involving lookups due to environment variables
smaller test cases for test 'bench_msm'
