This update introduces new field and curve API's, and enforces they are used consistently across the library. Furthermore it makes it possible to use fields, without having to initialize elliptic curves.
- #23 Remove unused exponent param of curves
- #58 Add a defined API for every field type, and have minor tweaks to all fields to implement it (Thanks @alexander-zw)
- #79 Separate field initialization from curves (Thanks @alexander-zw)
- #71 Add BLS12-381 (Thanks @yelhousni)
- #80 Add clang-tidy checks to library and CI
- #82 Convert tests to use Google test (Thanks @alexander-zw)
- #83 Make run-clang-tidy return an error when linting fails
- #85 Add more unit tests for fields (Thanks @alexander-zw)
- #86 Add binary fields from libiop
- #100 Move utils in from libiop
- #75 Get rid of warning for unused constant PI, in complex field
- #78 Reduce prints when inhibit_profiling_info is set
- #79 & #87 Use std::size_t for all code, fix bugs introduced by #58
- #94 & #96 Fix bugs that make libff incompatible with libfqfft and libiop
- #103 Fix bugs that make libff incompatible with libsnark and add more tests for the field utils
Special thanks to all downstream projects upstreaming their patches!
- File structure changed: All field utils are now in
libff/algebra/field_utils/,Fp_modelis now inlibff/algebra/fields/prime_base/, and all other F_p^n fields inlibff/algebra/fields/prime_extension/. - The function
base_field_char()of all fields and curves have been renamed tofield_char(). - The provided fields used in curves have been moved to separate files so that they can be imported
separately from
[field name]_fields.hpp. However they are still accessible from the init file.
- #20 Improve operator+ speed for alt_bn, correct the corresponding docs, and reduce code duplication.
- #50 Add mul_by_cofactor to elliptic curve groups
- #50 Add sage scripts for altbn and mnt curves, to verify cofactors and generators
- #52 Change default procps build flags to work with Mac OS
- #19 Fix is_little_endian always returning true
- #20 Fix operator+ not contributing to alt_bn_128 profiling opcount
- #26 Remove unused warnings in release build
- #39 Update Travis Config for newer Ubuntu mirror defaults
- #50 Fix incorrect mnt4 g2 generator
- #54 Fix is_power_of_two for n > 2^32
- #55 Throw informative error for division by zero in div_ceil
