This passage is intended to introduce how to set different kinds of parameters for password recovery attack type you choose, Brute-force, Mask and Dictionary. They would accelerate Office/PDF/RAR/ZIP password recovery with Office/PDF/RAR/ZIP Password Genius.
Brute-force is a commonly-used password recovery attack type.
When you choose Brute-force, Length and Range are two features which could largely improve password recovery progress. Once all of optional parameters belong to them are set and "Start" button is clicked, password recovery program will begin to check all possible password combinations one by one, until it finds one that can successfully open imported file. Then it would stop work and show imported file correct password.
When you know probable number of password characters, please set password Length, including Minimal password length and Maximal password length, which can reduce amount of password combinations. So password recovery time will be shortened comparing to when you don't do anything. You can set it like this. It means the password would not less than 1 character and not more than 8 characters. Only password consisting of 1/2/3/4/5/6/7/8 characters will be checked.
In this part, password characters type and characters stored in special location of password can be set. It would also shorten password recovery time.
2-1 Make sure which characters password probably consists of, and check box of All caps latin(A-Z), All small latin(a-z), All digits, All special symbols, Space(blank key), or All printable.
2-2 Type characters password begins with in Start from input box.
For example, suppose you know the forgotten password begins with "ab", you can type "ab" in Start from input box. Then only passwords beginning with "ab" can be checked after you click "Start" button.
2-3 Enter characters password ends with in End at input field.
For example, when you know the forgotten password ends with "cd", you can type "cd" in End at input field. Then only passwords ending with "cd" can be checked whether they can open imported encrypted file.
2-4 Another option is User-defined, which could specify characters that are surely included in password.
For example, if you know forgotten password includes "acd", you can type "acd" directly in User-defined box. Then only passwords including "acd" can be checked whether they are the encrypted file password.
Tips: If you can make sure the characters and their sequence in forgotten password, you can choose Mask password recovery attack type and set Mask instead of User-defined parameter.
If you still cannot understand how to set above four parameters according to what you know, some examples below will show you how to do settings for Brute-force attack you choose.
Eg. 1) Suppose you know the password consists of numbers and letters, and what the password starts with.
For example, when password starts with "ab", you can enter "ab" in Start from and check box of All caps latin, All small latin and All digits.
Probable password would be like this, ab???????? ("?" represents the characters you don't know).
Eg. 2) When you know the password consists of only letters and which characters the password ends with, follow below to set. Type ending characters "cd" in End at and check All caps latin, All small latin.
Password found out at last would be like this, ?????cd.("?" represents the characters you don't know)
Eg. 3) When you just know the characters password starts with and ends with, set Start from and End at options please. Type starting charcters "ab" in Start from and ending characters "cd" in End at box.
Password would be possibly like this, ab????cd. ("?" represents the characters you don't know)
Eg. 4) When you don’t know what kind of characters the password consists of, but you know what are surely included in password, check All printable and set User-defined please. Type the characters you know, such as "acd" in User-defined input box.
Probable password would be acd?????, a???cd??, c???ad??, d??ac???, ?????acd, ?????cda etc similar characters combinations that include characters "acd". ("?" represents the characters you don't know)
Mask is also called Brute-force with Mask, so it can be set based on Brute-force settings. For example, some options in Range can be set like Brute-force, such as characters type, Start from, End at option.
Now the only but most important paramater you need to set for Mask password attack is Mask parameter. The feature would speed up the password recovery progress undoutedly. Choose it when you partly know forgotten password and the their sequence stored in password. Otherwise, Brute-force has been effective enough to recover password.
Keep the sequence of characters in original right password, write down the characters you know and use "?" instead of characters you don’t know.
The followings are some examples showing how to set Mask based on Brute-force when you choose Mask.
Eg. 1) If you know the password consists of numbers and letters, password length is 5 and what the password starts with "ab", set it like this. Check box of All caps latin, All small latin and All digits, and type ab??? in Mask input box. Probabe password would be like this, ab???. ("?" represents the characters you don't know)
Eg. 2) If you know the password consists of only letters and the password ends with "cd", and password length is 6, follow below to set. Check box of All caps latin, All small latin, and enter ????cd in Mask input field.
The password you want to find should be like this ????cd.
Eg. 3) If you just know the password starts with (ab) and ends with (cd), and password length is 7, set Start from, End at and Mask options please. Now you can check box of All printable, enter ab in Start from and cd in End at, or directly type ab???cd in Mask input box.
Forgotten password you need to find with Mak attack type should be like this, ab???cd.
When you choose Dictionary attack type, password recovery program will check passwords in Dictionary file to look for one which can open encrypted file successfully. So the passwords numbers saved in Dictionary file will influence the speed of password recovery. Having a dictionary file as accurate as possible would make password recovery more effectively.
There are two sources you can get a dictionary file. One is the default dictionary file provided by password recovery program, the other is one password file created or found by us.
Step 1: Make sure which passwords you can use to create dictionary file.
1-1 Commonly-used passwords.
Generally, they are simple passwords but are still used frequently, such as 12345, 12345678, 11111111, 00000000, 88888888, abc, abc123, admin, ABC123 etc. If you don't know, you can search the Internet.
1-2 Old or ever-used passwords.
1-3 Some special characters, such as phone number, birthday, door passcode, email password, computer user logon password, Facebook password etc you use in other situations.
Step 2: Type password in a new notepad and save as dictionary file.
Open a new notepad, and type passwords one by one, one password in one line. And then save it on your computer. It would be a txt file including all passwords you want to use for Dictionary password recovery.
Step 1: Choose Dictionary attack from drop-down list of Type of attack.
Step 2: Click on Dictionary tab and choose a dictionary file.
2-1 Click on "Dictionary" tab under Encrypted File box, and click Select Dictionary button to browse and select the dictionary file you create. It will be seen in Dictionary file path box.
2-2 If you don't choose any dictionary file, default dictionary file will be used to recover encrypted file password.
If you want to use default dictionary to recover password, follow below to do.
Default dictionary has been imported automatically, when you run password recovery program. But you still can do something to make password recovery faster when choose default dictionary. For example, if you know the minimal password length, you can set Start line, because passwords in default dictionary is listed by password length.
When all of setting have been made for password attack type you choose, now just need to click Start button to recover Office/PDF/RAR/ZIP password.
