Cobra is the first member of the Intelligent Computer Solutions's CS hardware accelerator family designed to enhance and accelerate the process of file password recovery. Cobra works seamlessly with password recovery applications such as Password Recovery Tool Kit (PRTK) and Distributed Network Attack (DNA) by AccessData. Cobra's special focus is on hard-to-crack algorithms used by RAR or Office 2007 file formats, where the recovery process is very slow when using only software solutions, even with high-end PCs. User can stack up to four Cobra units by using the Cobra expansion slots. The cell requires only one power supply to power and one USB connection to a PC. The user can gradually add acceleration by adding Cobra units as needed, increasing computational power as each cell increases performance.
