Create a program that has a simple graphical interface using "Kivy", an environment cross-platform by Python.
When this program starts up, it will load a file (“users.csv”) that for each line will have a user and the SHA1 of the password, with the following format:
"user": "passwordinSHA1"
The graphical interface will have only two text fields, "username" and "password" (in plain text, but hidden when typing) and a "check" button. If the user exists and the password is correct, it will display an "OK" message. Otherwise, an "ERROR" message.

The class has the following fields: count, first, middle, last and suffix.2. The class has a constructor that receives one string parameter named name whosedefault value is an empty string (that is, calling the constructor with no parameterssets the value of name to an empty string). The constructor initializes all fields basedon the value of name, as explained next:– The value of count depends on the number of words in name. For example,given the name Robert John Downey Jr then count is 4.– If name has one word then it has a first name.– If name has two words then it has a first and last names in that order.– If name has three words then it…
