 - Error management: The original code did not handle errors in a consistent or secure manner, often panicking and revealing sensitive information. I added proper error handling and ensured that any errors that occur do not reveal sensitive information.

I added input validation to ensure that only valid input is accepted, and output validation to ensure that any sensitive information is displayed only to authorized users.
