Refactor code for improved readability and maintainability.

[Riyan-Mo]

• Imported only necessary functions from crypto module
• Added type annotations to function parameters and return values
• Utilized template literals for string concatenation
• Improved error handling with async/await
• Applied destructuring for cleaner code and reduced redundancy
• Ensured consistent parameter naming across methods

These changes enhance the code's clarity, maintainability, and adherence to best practices.
