A simple script for searching the password for T5577. The script creates a
dictionary starting from the entered starting year to the entered ending year.
There are two search methods - DDMMYYYY or YYYYMMDD. Checking the entire year
takes about 1 minute and 50 seconds. Date from 1900 to 2100. The script may be
useful if the password is, for example, a date of birth.
