The primary goal of cRARk is to
recover (crack) your forgotten password on RAR archives.
Rar/WinRar versions 2.x-3.x-4.x up to 4.0 are supported.
Please bear in mind you have quite no chance to crack unknown password (longer than 6-7 symbols) if you have no additional info about it.
This is command-line utility for Win32, Linux, Mac OS.
RAR security overview
RAR/WinRAR archiver version 2.x used its proprietary, but rather strong encryption algorithm. At least no RAR 2.0 attacks were known except brute force for password recovery.
Starting from version 3.0, RAR has been using a strong AES algorithm, which also doesn’t allow any attacks more effective than the brute force. Besides, the key derivation function uses more than 70000 SHA-1 transformations and brute force rate on modern CPU is very low, only several hundreds of passwords per second. This carries inference that RAR 3.x password encryption is one of the strongest between popular encryption systems in the context of brute force rate.
Advantages of cRARk are:
One of the fastest RAR password recovery software, uses extremely optimized MMX & SSE code
Optimization for latest x86 instructions: AVX, XOP, AES-NI for Intel Sandy Bridge and AMD Bulldozer processors
Support of RAR password recovery on NVIDIA GPU using CUDA technology, and using OpenCL, on NVIDIA and AMD/ATI GPU’s
Multi-volume, self-extracting, encrypted header archives support
Unique PCL language which is extremely efficient if user remembers any information about a forgotten password
Portability (DOS, Windows, Linux, Solaris, Mac OS versions are available)
