About The Project

The 128-Bit Arithmetic Toolkit is a C library that provides a set of functions for performing low-level bitwise math on 128-bit integers. It is designed to be highly efficient and is particularly well-suited for cryptographic applications where performance is critical.

Key Features

  • Optimized for Performance: The library is written in C and is highly optimized for speed.
  • Wide Range of Operations: The library provides a comprehensive set of bitwise arithmetic operations, including addition, subtraction, multiplication, and division.
  • Cryptographic Applications: The library is ideal for use in cryptographic applications that require high-performance 128-bit arithmetic.

Technical Details

The library represents 128-bit integers as an array of four 32-bit integers. The arithmetic operations are implemented using a combination of bitwise operations and carry propagation. The library is designed to be highly portable and can be easily integrated into any C project.
