Mine is fast, memory-efficient, single-header minimal cryptography implementation for small-medium projects that cannot afford to link to external libraries.

⚠️ Archive Notice

It was created purely for educational purposes and should not be used in production.

I’d like to sincerely thank everyone who showed interest, or learned something from this project. Your support means a lot to me!

If you're interested in what I'm currently building, follow me on GitHub to stay updated on new projects, tools, and ideas.

Overview

It all started with ripe that depends on third-party library (initially OpenSSL then Crypto++) linked statically. However after deploying residue with ripe to older distributions of linux, we learnt that portability is an issue for ripe as minimal library (because of it's dependencies). So we started to implement standards forming Mine.

I was very careful with my implementations and have over 50 test cases in-place.

Installation (API)

Simply copy mine.h and mine.cc from package/ directory to your project or your local machine.

Alternatively, feel free to link it as shared or static library (you will need to compile yourself)

Installation (CLI Tool)

You can either download binary for your platform via releases page or using NPM

npm install -g mine-linux@latest
sudo ln -s `which mine-linux` /usr/local/bin/mine

npm install -g mine-darwin@latest
sudo ln -s `which mine-darwin` /usr/local/bin/mine

Features

Mine supports following features:

• Base16 Encoding
• Base64 Encoding
• RSA [RFC-3447]
• AES [FIPS Pub. 197]
• ZLib (Depends upon libz)

This is what we are aiming for minimal crypto library.

Notes

• It is natively developed on macOS and Linux operating systems
• It is fast with compiler optimization level 1 (or higher)
• You need to implement BigNumber to use RSA, for unit tests we use Integer from Crypto++
• RSA currently does not support signing & verification or reading keys from PEM files

Quick Reference

Base16

• mine::Base16::encode(str);
• mine::Base16::encode(str.begin(), str.end());
• mine::Base16::decode(encoding);

Base64

• mine::Base64::encode(str);
• mine::Base64::encode(str.begin(), str.end());
• mine::Base64::decode(encoding);
• mine::Base64::decode(encoding.begin(), encoding.end());
• mine::Base64::expectedLength(n);

AES

std::string random256BitKey = mine::AES::generateRandomKey(256);

mine::AES aesManager;
aesManager.encrypt(b16Input, hexKey, mine::MineCommon::Encoding::Base16, mine::MineCommon::Encoding::Base64); // takes base16, encrypts and returns base64

aesManager.setKey(random256BitKey); // now use this key
aesManager.encr(b16Input, mine::MineCommon::Encoding::Base16, mine::MineCommon::Encoding::Base64); // don't need key with requests
aesManager.decr(b64Input, mine::MineCommon::Encoding::Base64, mine::MineCommon::Encoding::Raw); // Returns raw string

ZLib

• mine::ZLib::compressString(str);
• mine::ZLib::decompressString(str);
• mine::ZLib::decompressFile(outputFile, inputFile);
