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
Startup: Load configuration and environment variables.
Logging & Initialization: Set up modular architecture and log handlers.
Interface Selection: Choose between GUI, web-service, or CLI mode.
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.
Database Operations: Manage keys, logs, and encrypted data securely.
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
Configuration Loading: Retrieve database credentials from secure sources.
Connection: Establish a secure connection to MySQL, PostgreSQL, or MongoDB.
Authentication: Validate user credentials and roles.
Operations: Perform actions like storing keys, logging events, and managing key expiry.
Response Handling: Return results or errors to the main application.
