The number of different characters is calculated as follows:
The two character strings are made to overlap as much as possible (bysearching for the longest common string and rotating as necessary). Thenumber of different characters (after comparing character-by-character)returns the number the system needs.
Example
Old password = "BDAFAG" (six characters)
New password = "ABC DBA" (seven characters)
After being rotated: "DBAABC " (seven characters)
==> Number of different characters = 4
