[answered] Modern password systems don's store the actual passwor


Modern password systems don's store the actual password for a use they store a string that is known as a "hash". A hash has special properties, notably that the input to a hash function always returns the same output and that if you have the hashed output it is impossible to reverse and find out the input that generated the hash.

A well known hash function is called MD5. The MD5 hash of the word "hello" is "5d41402abc4b2a76b9719d911017c592".

A better hashing algorithm is called sha512. This produces a much longer hash (technically this is still not used for modern password storage but it will do for our demonstration program.

Your goal is to create a password storage system. It must do the following things.

  • Allow a user to enter a username and password. If the password is correct it must tell the user that they have been granted access. If the password is incorrect it must tell them that they entered an incorrect username or password.
  • Allow an administrator to create new accounts. A new account should take 4 pieces of information: username, email address, password, and a password verification (enter it again). If the passwords match and the username or email address are not already in the system it should create a new record.
  • Users can get a special token if they forget their password (we won't implement this fully right now). If the user forgets the password, they can provide the email address for their username. If the email address is in the system it will print a random token value. (in the real world this would be used to reset the password for now it will do nothing.)
  • Passwords must be stored in hashed form. When you check the password you must check to make sure the user entered password matches the hashed password that is stored.
