Merging Zencrypt CLI Into A Web-App
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
Personal Reflection Initial Enhancement PlansZencrypt 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.utils.py: Contains encryption and hashing algorithms.cli.py: Provides command-line functionality.webapp.py: Manages the 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.
Planned Features for Zencrypt v5
