Excel tabela ima password

[Hitri]

Pitanje i pomoc

Imam MS Office 2013, nesto sam radio u Excelu onda sam preuzmem sa Microsofta tabelu ..... Porodični budžet1.xlsx, ona je lepo napravljena i uredjena, samo je za gledanje nista ne mozes u njoj mijenjati zato sto ima password, u VBA Project. workbook / proprerties.

Pitanje: kako skiniti password, da ta tabela bude od koristi.

Pozdrav.

password u excelu nije teško probiti jer se koristi jednostavan hash, pojednostavljeno "checksum" iako to zapravo nije.
Metoda probijanja je da se kombinacijom nasumičnog stringa koji se samo sastoji od slova "a" i "b" pronađe checksum koji je isti checksumu originalnog passwords. Za to postoje makro naredbe koje tako rade.
