Kryptoanalýza klasických šifrovacích algoritmů

Abstract

The aim of this thesis is to design and implement an application that will be able to encrypt and decrypt texts using chosen historical methods and also to perform cryptoanalysis of the cipher texts created by these methods. The first part of this thesis is focused on known ciphers and their principles. The second part describes cryptoanalytical methods for substitution and transposition ciphers. The last part talks about the application itself, describing its implementation, usage and functionality.
