Zencrypt Documentation

Overview

Zencrypt is a cryptographic project designed to enhance data security through encryption and hashing. The application is evolving from a command-line interface (CLI) to a modular, scalable, and user-friendly application featuring GUI and web-service capabilities. This document provides an overview of the project, enhancement plans, and the future roadmap.

Enhancement Plan for Zencrypt CLI

Zencrypt aims to address modern cryptographic needs by incorporating a modular structure, advanced encryption techniques, and user-friendly interfaces. The enhancement plan focuses on the following key improvements:

Core Enhancements

• UI/UX Integration: Add a graphical user interface (GUI) using frameworks like Tkinter or PyQt.

• Modular Structure: Transition from a single-file CLI script to a modular architecture.

• Web-Service Expansion: Introduce a Flask/Django-based web-service to allow remote encryption/decryption.

• Best Practices: Adopt industry standards such as configuration files, logging, and environment variables for secure secret handling.

Algorithms and Data Structures

• Advanced Cryptography: Integrate elliptic-curve cryptography (ECC) and Argon2 hashing.

• Concurrency: Optimize large file encryption using multithreading or multiprocessing.

• Data Handling: Use sophisticated data structures like queues and Merkle trees to enhance performance.

Database Integration

• Secure Storage: Store keys, logs, and user information in a SQL or NoSQL database.

• Authentication: Implement user authentication and role-based access controls.

• Key Management: Add key rotation and expiry functionality for enhanced security.

Architecture and Workflow

High-Level Flowchart

1. Startup: Load configuration and environment variables.

2. Logging & Initialization: Set up modular architecture and log handlers.

3. Interface Selection: Choose between GUI, web-service, or CLI mode.

4. Execution:

   • GUI Mode: Launch a Tkinter/PyQt interface for user interaction.

   • Web-Service Mode: Run a Flask/Django server for remote operations.

   • CLI Mode: Present an updated menu with enhanced features.

5. Database Operations: Manage keys, logs, and encrypted data securely.

6. Shutdown: Close resources and save logs.

Modular Components

• config.py: Handles configuration and environment variables.

• crypto_ops.py: Contains encryption and hashing algorithms.

• cli.py: Provides command-line functionality.

• ui.py: Manages the GUI.

• web.py: Implements web-service functionality.

Database Flow

1. Configuration Loading: Retrieve database credentials from secure sources.

2. Connection: Establish a secure connection to MySQL, PostgreSQL, or MongoDB.

3. Authentication: Validate user credentials and roles.

4. Operations: Perform actions like storing keys, logging events, and managing key expiry.

5. Response Handling: Return results or errors to the main application.

Planned Features for Zencrypt v5

• Scalability: Built for long-term maintainability with a focus on modular design.

• Performance: Optimize large file handling and encryption tasks.

• Security: Incorporate advanced cryptographic algorithms and database-level security.

• User Experience: Simplify user interaction through a polished GUI and robust web interface.
