This is because in the password length area, by default, both the minimum password length and the maximum password length are 1. When brute force cracking is started for advanced Office password recovery, the cracking option setting is enabled by default, and the maximum password length is required to be greater than the minimum password length. When the maximum password length is the same as the minimum password length, brute force cracking cannot be started, resulting in the error "Password not found". In fact, we can solve the problem by changing the cracking settings of violent cracking, such as changing the number of password digits according to the memory of password, but we must ensure that the maximum number of digits is greater than the minimum number of digits.
