Tancrypt

Introduction

This C++ library provides simple cryptographic API with focus on RSA and AES.
Built on OpenSSL, but isn't a direct wrapper to make the usage as simple as possible.

This library is MIT licensed, so you can use it however you want in your projects!

Features

  • RSA encryption, decryption, sign and verify
  • AES encryption, decryption
  • Hashing

Requirements

  • C++ Standard : C++11 or later
  • Dependencies : OpenSSL3.0+


Example 
#include <iostream>
#include "tancrypt/rsa.hpp"

int main()
{
  // Makes life easier 
  using namespace tancrypt;

  // Keypair generation
  RSA::pkic key;
  key.generate_keypair(2048);

  // Preparing example buffer from string
  dutils::dbuffer data_in("Hewwo, I am secret ^.^");

  // Encrypting data
  dutils::dbuffer encrypted_buffer = RSA::encrypt(key,data_in);

  // You can check the results via helper function dutils::hexStr
  std::cout << "Original:" << data_in.toStr()<< std::endl;
  std::cout << "Original(hex):" << dutils::hexStr(data_in) << std::endl;
  std::cout << "Encrypted:" << encrypted_buffer.toStr() << std::endl;
  std::cout << "Encrypted(hex):" << dutils::hexStr(encrypted_buffer) << std::endl;

  return 0;
