Thesis Details
Útok na šifrování dokumentů OpenDocument s využitím GPU
The aim of this work is to extend Fitcrack with a module that allows the recovery of passwords from Open Document Format documents using either CPU or GPU to accelerate the process. The thesis further analyses the structure of the Open Document Format. Subsequently, it describes the functions and algorithms used to encrypt Open Document Format files. The GPU module is implemented with the use of the OpenCL framework. Both the time needed to recover the password and the acceleration of the process using the graphics card were measured. The work also contains a comparison between an existing tool that supports decryption of this format and the newly implemented module.
