Base

• Lightweight binary-to-text data de/encoders (C++03).
• Base64: canonical implementation.
• Base85: 17% to 08% smaller than Base64, still quotable.
• Base91: 19% to 10% smaller than Base64, still quotable, JSON, XML and TSV friendly.
• Base91: Encoded data can be "quoted", splitted with tabs, spaces, linefeeds and carriages.
• Tiny, self-contained, header-only.
• ZLIB/LibPNG licensed.

Sample

#include <iostream>
#include <string>
#include "base.hpp"

int main() {
    std::string encoded_64 = base64::encode("Hello world from BASE64! \x1");
    std::string decoded_64 = base64::decode(encoded_64);
    std::cout<< decoded_64 << " <-> " << encoded_64 << std::endl;

    std::string encoded_85 = base85::encode("Hello world from BASE85! \x1");
    std::string decoded_85 = base85::decode(encoded_85);
    std::cout<< decoded_85 << " <-> " << encoded_85 << std::endl;

    std::string encoded_91 = base91::encode("Hello world from BASE91! \x1");
    std::string decoded_91 = base91::decode(encoded_91);
    std::cout<< decoded_91 << " <-> " << encoded_91 << std::endl;
}
