This library includes big number integer arithmetic to support the aforementioned cryptographic algorithms. It supports unsigned big integer arithmetic with addition, subtraction, multiplication, division, reduction, inversion, GCD, extended Euclidean algorithm (EEA), Montgomery multiplication, and modular exponentiation. It provides useful utility functions, such as endianness management and conversion routines. The big integer library is likely to change in future releases.
There are also unit tests and some sample code.
This library is under active development. Future updates to this library may change the programming interfaces.
