stevefan1999 on 7:27 AM 01/05/2020: total length must be 5 first character can be anything second character must be '@' the rest (3-5) their sum of integer value of ascii character must be 300

Maksim on 5:58 PM 01/11/2020: first checks the key length (len must be 5), then checks the second character of the key (must be "@"), finally checks the last 3 characters, their sum in the ascii code must be 300, the first character can be any eg: 1@ddd
