Özet:

Both symmetric and asymmetric cryptographic algorithms must firstly be robust against brute force. The key needs to be choosen uniformly and randomly from the key space. It is possible to assure randomness by using statistical randomness tests which are also critical for other cryptographic issues as well. There is still an issue to be elaborated: the most well-known tool for attacking againts passwords namely dictionary attacks. These attacks are based on trying all keys from a particular subspace of the key space, which are composed of words from daily life and their variations. In this study we focus on the randomness of the keys but we are not interested with latter issue that is dictionary attacks. The one who use our tests to generate key must check it regarding specified dictionaries.
