Fitcrack is a distributed password cracking system. It can be used for recovering passwords securing various types of encrypted media like documents, archives, or disk volumes, as well as for breaking raw cryptographic hashes.

Thanks to the integration with Hashcat tool, Fitcrack provides a wide range of supported formats and great speed with the use of proper hardware. The computation is hardware-accelerated by using OpenCL technology, and thus, the cracking can be performed on all OpenCL-compatible CPUs, GPUs, FPGAs, DSPs, or coprocessors.

Our system is based on BOINC framework for distributed computing which allows Fitcrack to provide a relatively high level of automation without limiting the flexibility of the system, or administrator’s freedom of creating a custom design and configuration of a distributed network.

Fitcrack was created within the NES@FIT research group in the Faculty of Information Technology, Brno University of Technology, which gives the abbreviation “FIT” to the name of Fitcrack.
