base-x

BaseX encoder / decoder for C++

This is a fast base encoder / decoder of any given alphabet.

Example

// 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;
    // => 1LDlk6QWOejX6rPrJ

    return 0;
}

Compilation

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

66	base66::base66()	`ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_.!~`

How it works

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.
