"private users and businesses are required. The company should set the PCs to their employees so that passwords must be changed regularly. It should also provisions regarding the minimum length and difficulty to give the password," says Kempf.

Recent cases show how the choice of the password, the resistance can influence each crack attempts. Thus, the FBI has a report the Brazilian TV channel Globo twelve months, according to a tough time with a dictionary attack on a TrueCrypt-encrypted container by the teeth.
