# LLO - Low Level Obfuscation Utils

This repo contains a list of utils that will probably need to be implimented for LLO.

* llo::utils::generate_random_number, generate a random numerical value. 

```cpp
template <typename number_t>
concept is_arithmetic_t = std::is_arithmetic_v<number_t>;

template <is_arithmetic_t number_t>
number_t generate_random_number(const number_t minimum, const number_t maximum)
{
    using uniform_distribution_t = std::conditional_t<std::is_integral_v<number_t>, std::uniform_int_distribution<number_t>, std::uniform_real_distribution<number_t>>;

    std::random_device random_device;

    auto mt = std::mt19937{ random_device() };

    auto uniform_distribution = uniform_distribution_t{ minimum, maximum };

    return uniform_distribution(mt);
}
```

* llo::utils::hash_t templated class that contains unique std::uint64_t hash value for any given data. use std::hash to compute the hash.  https://en.cppreference.com/w/cpp/utility/hash. use std::hash<std::varient> to hash type T and a random uint64_t..

```cpp
template <class T>
class T hash_t
{
    hash_t hash(const T& data, std::size_t hash_result)
     : data {&data}, hash_result{hash_result}
    {}

    std::size_t hash_result;
    const T* data;

    public:
        static std::shared_ptr<hash_t> make(const T& data)
        {
            auto hash = std::hash<std::varient<T, std::uint64_t>>{}(data, llo::utils::generate_random_number<std::uint64_t>());

            return std::make_shared<hash_t>(data, hash);
        }

        T& get_data() const;
        std::size_t get_hash() const;
};
```
