Brute force attack to recover RAR archives passwords
What is RAR?
RAR is the native format of WinRAR archive. Like other archives, RAR files are data containers, they store one or several files in the compressed form. Nowadays RAR software used chiefly in saving space or compressing enormous quantity files. After you downloaded RAR file from Internet or other channels, you need to unpack its contents in order to use it.
The Top File Compression & Extraction Programs
Here we would like to present you the best archiving applications on the market, which including WinRAR, WinZip, RarZilla, 7-Zip, IZArc, PeaZip, Zipeg and ALZip.etc.
Recover a password protected RAR file
Method One: Take a chance
The RAR archive password sometimes is the URL from where the file was downloaded. Another possibility is the password could be within the filename [ ]. If these tips cant get a help, recovering the RAR password with a third party RAR password unlocker software is highly recommended. Well, just take a look at the decrypt process below.
Method Two: RAR Password Recovery tool – RAR Password Unlocker
RAR Password Unlocker is professional RAR and WinRAR password recovery software, which provides three types to attack RAR and WinRAR archives password, brute-force attract for recovering protection passwords or unlocks encrypted ZIP and RAR archives created with all versions of popular archivers.
There are three attack types of RAR Password Unlocker for you to recover RAR password which comprise brute-force attack, Brute-force with Mask attack and Dictionary attack.
1. Brute-force attack Try all possible combinations
Recommended: A
Using Brute-force attack of RAR Password Recovery can help you try all possible combinations to recover RAR password if you remember nothing about the password. Moreover, there is no doubt that its really hard to crack RAR password if the RAR password is very long or complex and the process could take ages.
2. Brute-force attack with mask If some password symbols are known
Recommended: AA
If you remember some symbols or length of the RAR password, brute-force with mask attack of RAR Password Recovery is better for you to save the recovery time by restricting the search area.

File Processing Systems
Even the earliest business computer systems were used to process business records and produce information. They were generally faster and more accurate than equivalent manual systems. These systems stored groups of records in separate files, and so they were called file processing systems. Although file processing systems are a great improvement over manual systems, they do have the following limitations:
Data is separated and isolated.
Data is often duplicated.
Application programs are dependent on file formats.
It is difficult to represent complex objects using file processing systems. Data is separate and isolated. Recall that as the marketing manager you needed to relate sales data to customer data. Somehow you need to extract data from both the CUSTOMER and ORDER files and combine it into a single file for processing. To do this, computer programmers determine which parts of each of the files are needed. Then they determine how the files are related to one another, and finally they coordinate the processing of the files so the correct data is extracted. This data is then used to produce the information. Imagine the problems of extracting data from ten or fifteen files instead of just two! Data is often duplicated. In the record club example, a member’s name, address, and membership number are stored in both files. Although this duplicate data wastes a small amount of file space, that is not the most serious problem with duplicate data. The major problem concerns data integrity. A collection of data has integrity if the data is logically consistent. This means, in part, that duplicated data items agree with one another. Poor data integrity often develops in file processing systems. If a member were to change his or her name or address, then all files containing that data need to be updated. The danger lies in the risk that all files might not be updated, causing discrepancies between the files. Data integrity problems are serious. If data items differ, inconsistent results will be produced. A report from one application might disagree with a report from another application. At least one of them will be incorrect, but who can tell which one? When this occurs, the credibility of the stored data comes into question. Application programs are dependent on file formats. In file processing systems, the physical formats of files and records are entered in the application programs that process the files. In COBOL, for example, file formats are written in the DATA DIVISION. The problem with this arrangement is that changes in file formats result in program updates. For example, if the Customer record were modified to expand the ZIP Code field from five to nine digits, all programs that use the Customer record need to be modified, even if they do not use the ZIP Code field. There might be twenty programs that process the CUSTOMER file. A change like this one means that a programmer needs to identify all the affected programs, then modify and retest them. This is both time consuming and error-prone. It is also very frustrating to have to modify programs that do not even use the field whose format changed. It is difficult to represent complex objects using file processing systems. This last weakness of file processing systems may seem a bit theoretical, but it is an important shortcoming.
