RAR Password Cracking Explained

Cracking a RAR file is no easy task as it takes a lot of time, a very powerful computer and, last but not least, highly efficient software program which is truly an ace up your sleeve.

RAR password protection employs very strong encryption algorithms which oftentimes significantly hampers searching process and results in slow performance. Apart from that the speed of password cracking also depends on the size of the RAR file (details).

All these challenges set very high standards and demanding requirements to the available RAR password cracking software solutions, i.e.:

  • customization of validation range
  • high-speed scanning of passwords
  • supporting AMD/NVIDIA graphics cards

Passcovery has been developing password recovering software since 2002. To crack passwords to open RAR files Passcovery recommends you to use the new edition of Accent RAR Password Recovery – software product that meets all the above mentioned requirements.

AcentRPR – Customization of Verification Range

Using a brute force attack while cracking a RAR password will result in too large a number of options to verify whereas a dictionary-based attack will produce very few password variants.

The perfect solution is range customization. This feature consists in adaptive cutting unnecessary arrays of passwords off and creating extra entries when it’s needed.

AccentRPR features the following range customization tools:

  • Brute-force with extended mask. The mask defines a list of possible characters for each position in the generated password and cuts off redundant validations.
    For example the following settings can be entered: symbol 1 – only digits, symbol 2 – only capitalized letter, symbol 3 – any symbol except digits, the last symbol – a special symbol (“1PassW0rD!”).
    Another program use case.
    Once at least the structure of a RAR password is defined the chances of its successfully cracking become very high;
  • Password mutation using dictionary attack. The scenario describes the rules of transformation of a password withdrawn from a dictionary and enables to cover all the variants obtained as a result of this transformation.
    For example the word “baseball” from the dictionary is transformed by AccentRPR into “B@seb@!!99”:

    This feature significantly increases the chances of successfully cracking RAR files even though the passwords may be quite strong.

To minimize the time needed to recover a RAR password you have to be ready to customize the searching process.

AccentRPR – Scanning of RAR Password Variants

The policy of WinRAR software developers is aimed at countering all possible attacks on archived files therefore RAR files can’t be cracked as fast as other formats (for example ZIP files).

To cope with the challenging task we optimized the source code of our software. So, Accent RAR Password Recovery is ready to exploit any hardware to get the maximum efficiency.

Crack RAR password with maximal speed. Anytime. Everywhere.

The processing algorithm of AccentRPR estimates the working system and actuates the compute core specially created and optimized for the existing CPU to engage it in the password recovery process. The software now is equipped with more than ten cores – one for each family of Intel and AMD CPU’s.

The algorithm described above ensures the highest possible speed of password searching using any modern hardware.

AccentRPR – GPU Support

Graphics cards with their enormous number of streaming processors really boost the cracking of strong passwords including passwords to open RAR files.

That means you can find a valid password dozens of times faster! It’s only a matter of the computer configuration and specifics of the RAR file you’re cracking.

When it comes to supporting graphics cards our software takes an uncompromising stand – AccentRPR is fully functional with all GPU’s whether AMD or NVIDIA produced over the last 7 years. And just as in the case with CPU the program employs 100% of GPU capacity.

The new edition of AccentRPR which we recommend to use for cracking password-protected RAR files now features improved support of AMD graphics cards with GCN architecture. In some cases acceleration is up to 30%.
