BaseXX

Header-only library for various Base Encoding & Decoding algorithms.
includes Base64, Base64-URLsafe, Base32, Base32-Hex, and Base16.
Based on RFC4648

Usage

#include "BaseXX.h"

int main()
{
    std::string str{ "Hello, World!" };

    {  // Base64[-URLsafe]
        std::string encoded_text        { base64::encode(str) };
        std::string urlsafe_encoded_text{ base64::encode_urlsafe(str) };
        std::cout << "Base64 Encoded Text: "         << encoded_text         << std::endl;
        std::cout << "Base64 URLsafe Encoded Text: " << urlsafe_encoded_text << std::endl;

        std::string decoded_text        { base64::decode(encoded_text) };
        std::string urlsafe_decoded_text{ base64::decode_urlsafe(urlsafe_encoded_text) };
        std::cout << "Base64 Decoded Text: "         << decoded_text         << std::endl;
        std::cout << "Base64 URLsafe Decoded Text: " << urlsafe_decoded_text << std::endl;
    }
    
    {  // Base32[-Hex]
        std::string encoded_text    { base32::encode(str) };
        std::string hex_encoded_text{ base32::encode_hex(str) };
        std::cout << "Base32 Encoded Text: "     << encoded_text     << std::endl;

        std::cout << "Base32 Hex Decoded Text: " << hex_decoded_text << std::endl;
    }
    
    {  // Base16
        std::string encoded_text{ base16::encode(str) };
        std::cout << "Base16 Encoded Text: " << encoded_text << std::endl;

        std::string decoded_text{ base16::decode(encoded_text) };
