Method Detail

generateVirtualKeyboardSequence

public static java.util.List<java.lang.String> generateVirtualKeyboardSequence(PasswordType passwordType,
                                                                               java.lang.String passwordValue)

Generates a valid virtual keyboard sequence for the given password type, and current password value. If a current password is given, it is guaranteed that the password chars will be contained on each sequence, allowing more possible characters than the limit of buttons * chars per button. If the current password is null, that limit must be respected. If the password type's input method is not PasswordInputMethod.VIRTUAL_KEYBOARD, returns null.
