Cryptanalysis of Block Cipher: Method Implementation

The study of techniques and methods to extract the original text from encrypted texts is called cryptanalysis. Nowadays, the process of ‘breaking’ cryptographic methods by analyzing them is called cryptanalysis. Cryptanalysis is essentially an approach that considers all usable information regarding the investigated techniques as well as the protected data and parameters. By cryptanalysing ciphertexts using block ciphers, this paper describes the implementation of cryptanalysis techniques. We show how the message is recovered without errors despite the use of simple algorithms. This paper will enhance students' and researchers' understanding of cryptanalysis. The ways in which numerical equations are used to analyze protected information systems to identify shrouded components and vulnerabilities are also described. In this context, the major challenges are to understand these techniques and the use of the CrypTool program to answer questions such as: how is each tool selected?; how are they connected?; and what are the inputs and the outputs for each tool? All these challenges are explained using texts or figures
