A field can be initialized by defining the underlying structure or by passing an irreducible polynomial along with a field characteristic to the initializer.

Validation (valid irreducible polynomial, valid prime number) of arguments is not performed.

Polynomial can be initialized seperately. Coefficients are stored in little-endian order.

• Basic arithmetic operations modulo Irreducible polynomial:
  • GF_elem_sum
  • GF_elem_diff
  • GF_elem_prod
  • GF_elem_div
  • GF_elem_get_complement
  • GF_elem_get_neutral
  • GF_elem_get_unity
  • GF_elem_get_inverse

• CMake (version 3.10 or higher)
• GCC

Open the terminal and follow these steps:

1. Clone the repository:

   git clone [email protected]:artem-burashnikov/ff-libc.git

2. Navigate to the project root:

   cd ff-libc

3. Generate Makefile using CMake:

   mkdir build && cd build;
   cmake ..

4. Build a static library:

   cmake --build . --clean-first
