Option 1: Authentication SystemFor security-minded professionals, it is important that only the appropriate people gain access to data in a computer system. This is called authentication. Onceusers gain entry, it is also important that they only see data related to their role in a computer system. This is called authorization. For the zoo, you will developan authentication system that manages both authentication and authorization. You have been given a credentials file that contains credential information forauthorized users. You have also been given three files, one for each role: zookeeper, veterinarian, and admin. Each role file describes the data the particular roleshould be authorized to access. Create an authentication system that does all of the following: Asks the user for a username Asks the user for a password Converts the password using a message digest five (MD5) hasho It is not required that you write the MD5 from scratch. Use the code located in this document and follow the comments in it to perform thisoperation. Checks the credentials against the valid credentials provided in the credentials fileo Use the hashed passwords in the second column; the third column contains the actual passwords for testing and the fourth row contains therole of each user. Limits failed attempts to three before notifying the user and exiting the program Gives authenticated users access to the correct role file after successful authenticationo The system information stored in the role file should be displayed. For example, if a zookeeper’s credentials is successfully authenticated, thenthe contents from the zookeeper file will be displayed. If an admin’s credentials is successfully authenticated, then the contents from the adminfile will be displayed. Allows a user to log out Stays on the credential screen until either a successful attempt has been made, three unsuccessful attempts have been made, or a user chooses to exitYou are allowed to add extra roles if you would like to see another type of user added to the system, but you may not remove any of the existing roles.
