Implement Encryption for Sensitive Data and Switch to .env for Configuration Storage
This commit introduces several significant changes to improve the security and configuration management of the application.
Encryption of Sensitive Data: We've introduced encryption for sensitive data such as database passwords. This is done using the Blowfish algorithm. The encryption and decryption methods are added to the Utilities module. The encryption is applied when the user enters their database password during the first run setup. The encrypted password is then stored in the .env file. When the application needs to use the password, it is decrypted using the key that was generated during encryption.
Switch from YAML to .env for Configuration Storage: The application now uses a .env file for storing configuration data instead of a YAML file. This change was made to take advantage of the .env file's ability to store environment variables, which can be easily accessed by the application. The .env file stores the database username, encrypted password, encryption key, and database name.
First Run Setup Changes: The FirstRunInit class has been updated to ask the user for their database details, encrypt the password, and store these details in the .env file. It also checks if any of the necessary details are missing and runs the first run setup if they are.
Database Connection Testing: The DatabaseManager class now decrypts the password before using it to test the database connection. It also checks if the password or key are nil before attempting to decrypt the password.
Logging: A new LoggMan class has been added to handle logging. This class provides a simple method for logging messages, which can be used throughout the application to log errors or other important information.
Bug Fixes and Error Handling: Several bugs were fixed and error handling was improved. For example, a bug that caused the application to crash if the .env file was missing has been fixed. Also, the application now checks if the .env file exists and creates it if it doesn't.
These changes significantly improve the security, reliability, and usability of the application.

Detailed Refactoring of Database Interaction
1. **Refactoring of Database Interaction Methods** - Refactored the `store_services` method in the `DatabaseManager` class to handle an array of services instead of a hash. This change was made to simplify the interaction with the database and to avoid unnecessary complexity in the data structure. - The `store_services` method now iterates over an array of services and inserts each service into the database with a default status of true. This design choice was made to ensure that all services are active by default. 2. **Modification of Database Schema** - Modified the `create_services_table` method in the `DatabaseManager` class to create a table with only two columns: `id` and `services`. This change was made to align the database schema with the new data structure used in the `store_services` method. - The `status` column was removed from the `services` table because the status of all services is now assumed to be true by default. 3. **Error Handling and Debugging** - Encountered a `Sequel::DatabaseError` with the message "Operand should contain 1 column(s)" during the execution of the `store_services` method. This error was caused by an attempt to insert a hash into a single database column. - The error was resolved by refactoring the `store_services` method to handle an array of services instead of a hash. 4. **Unorthodox Design Choices** - The decision to use an array of services instead of a hash and to assume that the status of all services is true by default may seem unorthodox. However, these design choices were made to simplify the interaction with the database and to avoid unnecessary complexity in the data structure. - These design choices also helped to resolve the `Sequel::DatabaseError` that was encountered during the execution of the `store_services` method. This commit represents a significant refactoring of the database interaction methods in the NETRAVE project. The changes made in this commit have simplified the interaction with the database and have resolved a `Sequel::DatabaseError` that was encountered during the execution of the `store_services` method. |

Refactoring and Enhancing Database Management and System Information Gathering
In this commit, we've made substantial changes to the DatabaseManager and SystemInformationGather classes to improve the functionality, efficiency, and maintainability of the system.
Refactoring DatabaseManager: The DatabaseManager class was refactored to improve the separation of concerns. Initially, the DatabaseManager was responsible for creating an instance of SystemInformationGather, which was not ideal as it violated the Single Responsibility Principle. The responsibility of creating an instance of SystemInformationGather was moved to the FirstRunInit class, which is more appropriate as it is responsible for the initial setup of the system. This change improves the maintainability of the code and makes it easier to understand and modify in the future.
Adding Database Connection Test: A method test_db_connection was added to the DatabaseManager to test the database connection before attempting to interact with it. This method improves the robustness of the system by ensuring that a valid connection exists before proceeding. It also provides a better user experience by providing a clear error message if the connection fails.
Refactoring SystemInformationGather: The SystemInformationGather class was refactored to improve its functionality and efficiency. The methods ask_for_uplink_speed and ask_for_downlink_speed were modified to convert the user's input to Mbps immediately, reducing the need for conversion later. This change improves the efficiency of the system by reducing unnecessary conversions.
Adding Services Table: A new table for services was added to the database. This table stores the services that the system should be aware of, with each service represented as a boolean value. This change improves the flexibility of the system by allowing it to handle a variable number of services. It also improves the efficiency of the system by reducing the need to parse the services from a string each time they are needed.
Storing Total Bandwidth: The total bandwidth (the sum of the uplink and downlink speeds) is now calculated and stored in the system_info table. This change improves the efficiency of the system by reducing the need to calculate the total bandwidth each time it is needed.
Error Handling and Debugging: Throughout the process, various bugs and errors were encountered and fixed. These included issues with method arguments, missing method calls, and incorrect method usage. Fixing these issues improved the stability and reliability of the system.
In conclusion, this commit significantly improves the functionality, efficiency, and maintainability of the system. The changes made adhere to good software engineering principles, such as the Single Responsibility Principle, and make the system more robust and user-friendly.

Refactoring for Modularity, Code Reuse, and Security Considerations
In this commit, we have undertaken a significant refactoring of the codebase to improve modularity, promote code reuse, and consider security aspects.
Modularity and Code Reuse: We introduced classes and modules to better organize the code and facilitate code reuse. Specifically, we created a new Utilities module to hold common methods that are used across different parts of the application. This module includes methods such as convert_speed_to_mbps, services_to_hash, and calculate_total_bandwidth. By placing these methods in a module, we can include this module in any class that needs these methods, thereby promoting code reuse and reducing duplication.
We also created two new classes, SystemInformationGather and DatabaseManager. The SystemInformationGather class is responsible for gathering system information, such as uplink and downlink speed, and services. The DatabaseManager class handles database operations, including testing the database connection, creating the system information table, and storing system information in the database. By encapsulating these responsibilities within their respective classes, we have made the code more organized and easier to maintain.
Database Connection Details: We made a decision to store the database connection details in a config file (config.yml) instead of the database itself. This decision was made for security reasons, as storing these details in the database could expose them to potential security risks. Storing these details in a config file allows us to better control access to these details.
Database Encryption: We discussed the possibility of encrypting the database for additional security. While we have not implemented this feature in this commit, we have laid the groundwork for it by discussing potential libraries/gems that could be used for this purpose. This is an area that we will revisit in the future.
System Information Gathering: We wrote methods to gather system information, such as uplink and downlink speed, and services, and store this information in the database. This information will be useful for monitoring system performance and for making decisions about resource allocation.
This refactoring effort has made the codebase more organized, easier to maintain, and more secure. It also aligns with our project goals and roadmap. However, it's important to note that with any refactoring effort, there may be potential issues or trade-offs. We will need to thoroughly test the refactored code to ensure that it works as expected and that there are no unintended side effects.
