Keyverse Library

Overview

Keyverse Library is a C++ implementation for secure key-value storage. It provides functionalities such as encryption, decryption, GUID generation, and data persistence using AES-128-CBC encryption with OpenSSL.

Features

• Configuration Handling: Reads configurations from a JSON file.
• Encryption & Decryption: Utilizes AES-128-CBC encryption.
• Data Persistence: Saves and retrieves encrypted key-value data.
• GUID Generation: Generates unique identifiers.
• C API Integration: Provides an external C API for interaction.

Dependencies

To build and run Keyverse Library, ensure you have the following dependencies:

• C++ Standard Library
• OpenSSL (for encryption & decryption)
• Boost.Asio (for networking)
• nlohmann/json (for JSON parsing)
• Filesystem Support (C++17 or later)

Installation

1. Clone this repository:

   git clone https://github.com/your-repo/keyverse-library.git
   cd keyverse-library

2. Install dependencies:

   • On Ubuntu/Debian:

     sudo apt-get install libssl-dev libboost-all-dev

   • On macOS:

     brew install openssl boost

3. Compile the library:

   g++ -std=c++17 -I/usr/include -L/usr/lib -lssl -lcrypto -o keyverse keyverse_library.cpp

Usage

Creating a Context

KeyverseContext* ctx = kv_create_context("config.json");
if (!ctx) {
    std::cerr << "Failed to create Keyverse context" << std::endl;
}

Storing a Key-Value Pair

kv_set(ctx, "username", "john_doe");

Retrieving a Value

char* value = kv_get(ctx, "username");
std::cout << "Value: " << value << std::endl;
kv_free_string(value);

Generating a GUID

char* guid = kv_generate_guid();
std::cout << "Generated GUID: " << guid << std::endl;
kv_free_string(guid);

Saving Data

kv_save(ctx);

Destroying the Context

kv_destroy_context(ctx);
