Password strength measurement

The thesis describes the theme of password measurement and more thoroughly deals with the Zxcvbn algorithm which I localize into Czech and extend its functionality in order to allow easier localization to other languages. In the theoretical part, I deal with the topic of password measurement on the basis of different studies: why shall we measure password strength, the way it should be done, and characterization of some commonly used password meters. In the practical part I analyze real Czech passwords leaked from LinkedIn in 2012. I examine the need to use Czech dictionaries and Czech keyboard layout, I justify the need to translate the feedback, and deal with the problem of declension and use of words variants. I also describe the technical functionality of the algorithm, how it is deployed, and the nature of the changes made by me. The practical result of the bachelor thesis is based on theoretical part of the thesis: Zxcvbn algorithm modified for use in Czech conditions, especially in the environment of the University of Economics, extended by the possibility of easier localization inzo other languages
