Description:

The cRARk program is designed to determine a forgotten password for RAR-archives. This program operates adequately with RAR-archives versions 2.x and 3.x. To proceed with cRARk program you need a computer with the Pentium compatible processor or later. It is recommended to use as powerful processor as possible (the code is optimized for Pentium III/4/AMD/Core 2). From v. 3.2, cRARk supports NVIDIA GPU from GeForce 8xxx with CUDA support and computing capability 1.1.

cRARk is the tool for professionals, no GUI or great service is provided. But it tries to maximize your abilities for passwords definition and to minimize search time. cRARk uses Password Cracking Library (PCL), a very powerful tool allowing you to define rules to generate passwords. The rate of password search should be about of 100 password per second on modern powerful computer, so finding the 6-characters password of lower case Latin letters will need about a month. In the GPU the rate could achive 2000-3000 p/s. Rate for dictionary attack is about 50 pass/sec (GPU is not supported). The stored files rate is slower and depends of file length.
