GPU akcelerované útoky hrubou silou se zaměřením na uživatelská hesla

GPU-based acceleration of brute-force attacks focused to user passwords
Abstract:
This thesis looks into brute-force attack and dictionary attack using GPU with OpenCL. The theoretical part of this thesis discribes architecture of GPU, the difference between GPU and CPU a specification of OpenCL language. The practical part is dedicated to implementation of attacks. At the end are tables with meassured time values of password cracking.
