Create a robust encryption system for generate password

Create a robust encryption system for generate password

Cyber Security is a key issue to protect our daily documents and applications stored and submitted in various platforms. Having a sturdy coding system to our generated positive identification is incredibly essential during this perspective. Your task is to make a pleasant and swish encrypted positive identification generator. Follow the directions fastidiously to make the positive identification generator. [5 Marks]

a. Take a 5 digit integer number from user. Use a function named Input_Number() to require the amount from user. If the amount isn't exactly of 5 digits, provides a warning message to user and exit/abort the program.

b. In case of a 5 digit number, pass each digit of the amount to a user defined function named character_extractor() which might return a character like a digit. Character related to each digit will be within the following sequence.

c. Finally, pass your extracted characters during a user defined function named password_generator() to generate a 5 length password.

d. Show the password on screen.
