Recommended Article: Sometimes, the password can be recovered instantly. This is only possible if the password protection is very poorly implemented.

It is different from the original password (and it usually looks quite odd), but it can be used instead of the original password.
You can use it to remove the protection from the document or to change the existing password. Unfortunately, you can’t determine the original password this way (the only exception is the case when the password is very short and some additional conditions are met). If you have several documents protected with the same password, you’ll be able to use the same fake password to unlock all of them. The fake password is likely to contain very exotic character combinations and if you make a mistake typing it you won’t be able to use it. Therefore, fake passwords should be typed very accurately (better use the clipboard).

If there are several documents to recover, each of them must be processed individually. International/Localization issues N/A Supported by the following LastBit software:,, Brute Force Attack is the most widely known password cracking method.
This attack simply tries to use every possible character combination as a password. To recover a one-character password it is enough to try 26 combinations (‘a’ to ‘z’). It is guaranteed that you will find the password. How long will it take? The two-character password will require 26*26=676 combinations. The number of possible combinations (and therefore required time) grows rapidly as the length of the password increases and this method quickly becomes useless.
Do you ready to wait for two months while your 9-character password is cracked? What about one hundred years for an 11-character password? Besides the maximal length of the character set you should also specify the character set i.e. The list of characters that will be included in the combinations.
The longer the character set is, the longer the required period of time is. Here is the problem: usually you have no idea of what characters are present in the password. On the one hand, you should specify all possible characters.
On the other hand, this can slow things down very much. Unfortunately, there are no common ways to determine what character set to use. It is more a question of luck and intuition. The only thing I can recommend is to begin with trying short passwords using the full character set.
Then you can increase the length of password simultaneously decreasing the character set to keep the required time good acceptable. If the password is case sensitive (this is the most common situation), there is another problem with the case. There are three options: 1) you can assume that the password was typed in lower case (this is most likely). In this case, the required time will stay the same but if the password contains upper case letters it will not be recovered.
2) you can try all combinations. The password is guaranteed to be found, but the process slows down significantly. A 7-character lower case password requires about 4 hours to be recovered but if you would like to try all combinations of upper case and lower case letters, it will require 23 days. 3) The third method is trade-off.
Only the most probable combinations are taken into consideration, for example 'password', 'PASSWORD' and 'Password'. The complicated combinations like 'pAssWOrD' are not. In this particular case the process slows down to one third of original speed but there is still a possibility to fail. You can reduce the amount of time required using faster computers (only the CPU speed is important. The amount of RAM, the performance of the hard drive and other hardware don’t affect the brute force speed), using several computers, choosing the fastest password crackers or tuning the brute force parameters wisely and accurately. You can use our software to estimate the time required for Brute Force Attack.
The table below shows the time required for Brute Force Attack depending on the password length and used character set. It is assumed that the attack is carried out on a single computer and the brute force speed is 500 000 passwords per second. Length of the password Character set lowercase letters lowercase letters and digits Both lowercase and uppercase letters all printable ASCII characters PASSWORD, Password, PAssword, pASSWORD etc), omission of one of the characters, doubling characters, inserting or replacing the character with the neighboring characters and so on. Usually the number of combinations is not very large and it is possible to test them all in a little time. Time Required: Depends on the variation depth, usually little What is Recovered: Original password Guaranteed result?
