Collect Turkish language word from Turkish Language Institue web site http://www.tdk.gov.tr/ and create turkish word file. It can be useful for cryptanalysis and brute force password attacks and appeare other turkish language features. Türk Dil Kurumu (TDK) web sayfasından Türkçe kelimeleri toplayarak Türkçe kelime dosyası oluşturur. Son çalıştırdığında program toplam 76187 kelime toplamıştır. Toplanan kelimeler Türk diline ait özelliklerinin çıkarılması, şifre saldırıları ve kriptanaliz işlemlerinde kullanılabilir.
