Microsoft Office Password Recovery Using GPU
Zobal, Lukáš ; Veselý, Vladimír (referee) ; Hranický, Radek (advisor)
This thesis describes the password recovery of Microsoft Office documents by expanding an existing tool Wrathion. The thesis explains the issue of digital document protection, modern encryption and hashing algorithms and rudiments of OpenCL standard. Next, the analysis of structure of MS Word, MS Excel and MS PowerPoint documents is performed, including all the versions since 1997. Using this knowledge, we create a draft and an implementation of improved DOC module for newer versions of the encryption, as well as a draft and an implementation of brand new modules for XLS and PPT formats and their newer variants DOCX, XLSX and PPTX. After that, we measure performance of the new modules and compare it with other competing password recovery tools.

System for Quality Control Management of Devices
Černý, Lukáš ; Hrivňák, Ján (referee) ; Hynek, Jiří (advisor)
This diploma thesis describes both the theoretical and practical part of the process of design and implementation of interactive computer software for the~management of~the~quality control of the~devices, assigned by SIGMA GROUP a.s., more precisely its Energo division, which is engaged in the maintenance and repair of pumping equipment. The theoretical part explains the concept of user experience, its acquisition methods, specification of~requirements and interface design methods. The next part is focused on the description of the~formats used by common text editors. Within the theoretical part is described the design of the interactive application itself. In the practical part there is a description of the main parts of the system and the conclusions from the system testing.

OpenXML Document Processing Library
Belica, Peter ; Očenášek, Pavel (referee) ; Burget, Radek (advisor)
This thesis describes the type of documents named Office Open XML, which are commonly known as OpenXML. Basic properties of these documents as well as their structure are explained. There is also an introduction to other technologies such as DOM and XHTML beacause of their inevitability in realization. Program library is designed to read these documents, build a DOM structure for them and export it as a XHTML file.
