This is a fast base encoder / decoder of any given alphabet.
// example.cc
// g++ -std=c++14 -o example example.cc
#include <iostream>
#include "base_x.hh"
int main() {
auto encoded = Base58::base58().encode("Hello world!");
std::cout << encoded << std::endl;

}- g++ and clang++ are supported.
- C++14 is required.

It encodes octet arrays by doing long divisions on all significant digits in the array, creating a representation of that number in the new base.
If you need standard hex encoding, or base64 encoding, this module is NOT appropriate.
